Notes

When the United States had discovered that the Soviet Union had built missile sites in Cuba and had placed missiles there that had offensive capabilities, our government went into action. We told the Soviet Union that we were placing a naval blockade around Cuba. We also said that any missile strike in the Western Hemisphere would be considered the same as if it were a direct strike on the United States. We indicated that we would stop Soviet ships headed to Cuba. There was a great deal of tension as many people thought the United States and the Soviet Union were heading toward nuclear war. There were ongoing negotiations during the crisis. Some negotiations were in the form of letters between President Kennedy and Soviet Premier Khrushchev. Other negotiations took place between other members of our government and the Soviet government. In the end, both sides decided that a diplomatic, not a military, solution was the best way to resolve the crisis. The Soviet Union agreed to remove th...

By definition, pressure is force over area, where force is supposed to be perpendicular to that area. It is measured in Pascals, Pa, which are equal to 1 Newton over square meter. One Pa is a small pressure. So `P = F/A.` In our case, the force P (weight is the force with which a body presses on its base) and the area A are given, so we only have to divide. `P = F/A = (100 N) / (2 m^2) = 50 Pa.` This is the answer. Note that we cannot be sure that the weight is distributed evenly over whole the base. In that case the number we found is the average pressure. This pressure also isn't very high. For example, a mosquito when it bites may create a pressure of about `10^14` Pa.

When one speaks about the setting, one must address both place and time.   The setting of place is most definitely the country of Nigeria on the continent of Africa. The reader can get even more specific in that the relationship between Nene and Nnaemeka takes place in the city of Lagos in a room at 16 Kasanga Street. When Nnaemeka goes to visit his father, the setting changes to an Ibo village in rural Nigeria.   In regards to setting of time in "Marriage is a Private Affair," we can assume it is a "fairly modern" setting; however, we are not told a specific time period. There is a city involved and a specific street, but there are also rural villages. Because there is letter-writing involved, it can be assumed that the story takes place before email was prevalent. Also considering that Chinua Achebe wrote the story in the 1950s, the reader can then infer that the time period is most likely the mid twentieth century. In regards to the interval of time, the story ta...

In 1971, fewer than 1,000 Australians reported in the census that Vietnam was their birth country; fifteen years later, after the end of the Vietnam War, more than 80,000 Australians reported being of Vietnamese origin. In the 2011 census, more than 180,000 Australians were of Vietnamese origin. As Vietnamese people started fleeing Vietnam, mainly for political reasons (and later for economic reasons), Australia was ending its "White Australia Policy." This policy, which started in 1901, restricted immigration to Australia to Europeans. In 1975, the Racial Discrimination Act, preventing discrimination based on race, was passed. As a result, Australia became more multi-cultural, but the country also experienced some backlash against Vietnamese immigration. Today, there are thriving Vietnamese communities and community organizations, and Vietnamese people are active in government, the arts, and other fields. However, in the 1980s, Vietnamese people were often blamed for violenc...

Tracy Chevalier uses a great deal of figurative language in Girl With a Pearl Earrin g. For example, when Griet meets Pieter, Pieter "looked me over as if I were a plump chicken he was considering roasting" (page 27). This is a simile, a form of figurative language, and it provides the reader with a vivid description of Pieter's gaze. When Griet is describing how, in the past, she had always gone to new places with her family, she says, "The new was woven in with the old, like the darning in a sock" (page 27). This simile uses a comparison of integrating new experiences with old experiences to the way a sock is knit together with old and new threads. It is an effective and vivid way to describe how Griet integrates new experiences into existing ones.   This type of figurative language is particularly effective when the author is discussing how Griet looks at paintings. For example, Griet thinks, when looking at one of Vermeer's paintings, "It was like l...

In The Bloody Chamber, Angela Carter’s collection of gothic, feminist retellings of classic fairy tales subverts patriarchal values by recasting women as the main protagonists of the stories rather than marginal characters on the periphery of the tales. By foregrounding the experiences of her female protagonists, Carter shows that the fairy tales that inspire her work uphold patriarchal values. Fairy tales often cast women as victims or monsters; she challenges these expectations by placing women in prominent roles in her gothic interpretations. For instance, in “The Tiger’s Bride,” the young female protagonist is initially presented as a “damsel in distress,” as a victim. However, she shows a strength that is not typical of women in fairy tales. Indeed, when The Beast admits that he values her because she is a virgin, she sardonically thinks “I wish I’d rolled in the hay with every lad on my father’s farm, to disqualify myself from this humiliating bargain” (61). She disregards the no...

This statement comes from Chapter 3 of Roll of Thunder, Hear My Cry . Cassie and her siblings have dug a deep ditch to get back at the driver of the white children's bus, as he always sprays them with mud. It is Stacey's idea to dig a hole so that the bus will get stuck in it on the way home, and Cassie and her siblings gleefully see that their plan works. All the white children must walk home in the rain, as Cassie and her family must do each day. The Logan children are jubilant about what they have done until Mr. Avery comes by after dinner to tell the Logan family that "they's ridin' t'night," meaning that white men are riding around trying to harass African-American people to prevent them from defending themselves. This threat is why Cassie says of Stacey in the statement on page 63, "I knew that his face was drawn and that his eyes had taken on a haggard look." This means that Stacey's face and eyes look worn and tired, as Stacey blames ...

Circe warns Odysseus that their journey will only be able to continue if they go to the halls of Hades, where he must consult with the spirit of Teiresias of Thebes. In Book X, after fleeing Lamos, the land of the giant Laistrygonians, Odysseus and his men arrive on the island of Circe. After making a random selection, Odysseus sends some of his men, who are both reluctant and frightened, to search around. Under the command of Eurylochus, they investigate the island. The men soon hear Circe at her loom, singing. Polites tells the others that somebody inside is either a god or a woman, adding, "Then let us quickly call." When they do so, Circe comes to the shining doors and invites them in. All except the cautious Eurylochus enter, and Circe offers them a feast. When they finish eating, however, she takes a magic wand and turns the men into swine and pens them. Having witnessed the men's fates, Eurylochus hurries back to tell Odysseus.  Odysseus hurries to the men. Fortuna...

You could argue that both stories present the idea that all human beings are inherently sinful and that we all make choices to avoid acknowledging that sinfulness for what it is; this unwillingness ultimately damages our relationships with each other and with God. As Young Goodman Brown walks into the forest, he thinks to himself, "'[Faith] is a blessed angel on earth; and after this one night, I'll cling to her skirts and follow her to Heaven.'" But this is not the way Faith works. One cannot simply put one's faith down and pick it back up again when it suits. We cannot voluntarily and cheerfully commit sin simply because we believe that faith and piety will be available to us later. This is not being honest, and it's like trying to trick God. In the story, Brown's strategy doesn't work. He is never able to regain his faith in the end. Similarly, Mr. Hooper's congregation understands, on some level, that his veil represents "secret sin,...

The story portrays Pahom’s greed and the devil’s mischief. The devil overheard Pahom boast about how he would not fear the devil if he had enough land. The statement was made during a conversation between Pahom’s wife and her sister from the city. The sister bragged about how they had better lives in the city compared to what Pahom’s wife and her family had in the countryside. She talked about the exciting social life and advanced amenities in the city. Pahom’s wife in defense stated that although they did not enjoy the benefits of city life, they had less complicated lives with minimal risks to their fortunes. Pahom took the opportunity to state that the only problem facing people in the countryside was insufficient access to land and it was in the same breath that he made the boast. The devil lured Pahom into his trap by offering him land. Pahom’s greed got the best of him, and he made a fatal mistake when the Bashkir’s made him an offer to acquire their land. In attempts to carve ou...

It sounds as though you are struggling to figure out an approach to this fairly complex assignment. Therefore, this answer will focus on helping you organize your paper into section and discuss the major points on which you should focus in each section. Since the assignment specifies that you should not use outside resources, you should base your theoretical approach on material from your class notes. If you have been studying postcolonial theory, two important concepts your instructor may have discussed are "hybridity" and "passing". If so, the introduction to your paper should point out that both stories can be approached from these perspectives as they are both about young women who appear to be of mixed white and black blood, although we do discover that Tite eventually is shown to be of Spanish rather than African-American descent. Your second section should give some historical background on Louisiana in the nineteenth century, and in particular its cultural h...

The O blood group is known as the universal donor because the blood can be transfused successfully to blood groups O, A, B, and AB. However, the O blood group cannot receive blood from any other group except the O blood group. Blood groups are determined by the presence or absence of the A and B antigens. Blood group O does not have either the A or B antigens on red cells, but it contains both the A and B antibodies in the plasma. It should also be noted that not all blood group O’s are the same because of the Rh factor which determines whether the blood group is positive or negative. Thus, blood group O is further categorized into O positive and O negative with O negative being the true universal red cell donor. The reason why blood group O can only receive from the same blood group is because the other blood groups contain antigens that are considered foreign by the recipient. The situation will force the O blood host to generate antibodies to fight the foreign antigen. The immune sy...

Cowardice is a lack of bravery. Boo Radley, Atticus, and Jem all show bravery at some points in the story. At other points, they seem to lack bravery, so one could say they display cowardice. Boo Radley hides away in his house, never going out when people can see him. Although readers don't know his motivations for his reclusive lifestyle except through the insight provided by his history and town gossip--or the children's imaginations--when Boo rescues Jem and brings him home, he does seem to display some cowardice. He stands in the corner in Jem's bedroom and doesn't come near or speak to the others in the room. When Scout leads him back to the bedroom before she leads him home, Boo stands over Jem with "an expression of timid curiosity on his face." If one equates timidity with cowardice, then Boo exhibits cowardice here. Atticus is portrayed as a highly courageous character. Throughout most of the book, he shows bravery rather than cowardice. However, if o...

The United States House of Representatives and the United States Senate make up Congress, which is the lawmaking body of the United States. This is the first similarity—both Houses can pass legislation, although bills involving taxation begin in the House of Representatives. Both Houses use committees and committee chairs to expediently handle business. Both lawmaking bodies have bylaws. Senators and representatives are elected by the people they represent in their home districts, although the direct election of senators was not a reality until 1913. Both Representatives and Senators often use their positions as stepping stones to get to other coveted governmental posts, such as Cabinet positions, the presidency, or gubernatorial positions. The Senate and House are also the best way for a regular citizen to reach out and affect government—when someone wants to see a bill passed, that citizen should write his/ her congressperson.  

Your introductory thesis statement depends on what the main point of your paper is and the audience to whom you are writing. A paper for a first-year composition course should aim to have a clear general argument for a lay audience, while a paper for an education course should show your knowledge of some recent research in the field. A post-graduate paper needs to focus on some very narrow issue and be supported by original research and detailed knowledge of the field. If you are writing a paper for a general writing course as opposed to a course within the education curriculum, you should probably take a stance that evidence of racial and socio-economic bias in standardized tests should make us reduce our reliance on this sort of testing. If you are completing an assignment in an education course, you should narrow your thesis to make an argument about the effect of this sort of bias on some specific population, such as students of a specific background applying to universities in a s...

Given equation is `xy' + y = xy^3` An equation of the form `y'+Py=Qy^n` is called as the Bernoullis equation . so, to proceed to solve this equation we have to transform the equation into a linear equation form of first order as follows =>` y' (y^-n) +P y^(1-n)=Q` let `u= y^(1-n)` => `(1-n)y^(-n)y'=(u')` => `y^(-n)y' = (u')/(1-n)` so , `y' (y^-n) +P y^(1-n)=Q` => `(u')/(1-n) +P u =Q ` so this equation is now of the linear form of first order Now, From this equation , `xy' + y = xy^3` => y'+(1/x)y =y^3 and `y'+Py=Qy^n` on comparing we get `P=(1/x) Q=1 , n=3` so the linear form of first order of the equation `xy' + y = xy^3 ` is given as => `(u')/(1-n) +P u =Q ` where` u= y^(1-n) =y^-2 ` => `(u')/(1-3) +(1/x) u =1` => `-(u')/2 +u/x=1` => `(u')-2u/x = -2` so this linear equation is of the form `u' + pu=q` `p=-2/x , q=-2` so I.F (integrating factor ) = `e^(int p dx) = e^(int (-2/x)dx) = e^(ln...

Photojournalists have been known, from time to time, to stage photographs to maximize their emotional, and political, impact. Even those, the vast majority, not staged for maximum effect, however, can still resonate powerfully with viewers and, consequently, affect public opinion and public policy. There is, perhaps, no better recent example than that of the three-year-old boy whose drowned body was photographed on a beach on the Turkish coast. The child's family had fled the war in Syria and, as happens, the boat on which they were sailing capsized. The image of the dead child quickly resonated with millions of viewers around the world, forcing regional governments to reassess their policies with regard to immigration. Susan Sontag had a long record of not just photographing images, but of studying and contemplating them. In 1977, she published On Photography , a compilation of her essays from 1973 to 1977. These essays constituted a meditation on imagery and its use and exploitat...

Cohesion vs Adhesion Cohesion : Cohesion is the attractive force between "like" molecules. Many properties of water such as surface tension occur because of cohesive forces between water molecules. Adhesion: Adhesion is the attractive force between the molecules in a liquid and a solid surface. Water When water is placed in a graduated cylinder, the adhesive forces between the water and the glass are stronger than the cohesive forces between the water molecules. The strong adhesive forces between the water and the glass, pull the sides of the water upwards along the glass forming a concave shaped meniscus. Mercury When mercury is placed in a graduated cylinder, the cohesive forces in the mercury are stronger than the adhesive forces between the mercury and the glass. The strong cohesive forces within the mercury pull it together forming a convex shaped meniscus. 

To evaluate the given equation `log_4(-x)+log_4(x+10)=2` , we may apply the logarithm property: `log_b(x)+log_b(y)=log_b(x*y)` . `log_4(-x)+log_4(x+10)=2` `log_4((-x)*(x+10))=2` `log_4(-x^2-10x)=2` To get rid of the "log" function, we may apply the logarithm property: `b^(log_b(x))=x.` Raise both sides by base of `4` . `4^(log_4(-x^2-10x))=4^2` `-x^2-10x=16` Add `x^2` and `10x` on both sides of the equation to simplify in standard form: `ax^2+bx+c= 0.` `-x^2-10x+x^2+10x=16+x^2+10x` `0=16+x^2+10x orx^2+10x+16=0.` Apply factoring on the trinomial. `(x+2)(x+8)=0` Apply zero-factor property to solve for x by equating each factor to `0` . `x+2=0` `x+2-2=0-2` `x=-2` and `x+8=0` ` x+8-8=0-8 ` `x=-8` Checking: Plug-in each `x ` on `log_4(-x)+log_4(x+10)=2` . Let `x=-2` on ` log_4(-x)+log_4(x+10)=2` . `log_4(-(-2))+log_4(-2+10)=?2` `log_4(2)+log_4(8)=?2` `log_4(2*8)=?2` `log_4(16)=?2` `log_4(4^2)=?2` `2log_4(4)=?2` `2*1=?2` `2=2`         TRUE Let `x=-8` on `log_4(-x)+log_4(x+10)=2.` `...

The housing projects in the story, like public housing in many cities, are isolated places, even though they might be in the middle of a city; they are isolated by poverty and usually by race. The image this gives us is of danger all around and no means of escape, which is reinforced in the same part of the story, in which Baldwin speaks of the boys being "surrounded by danger" (7) and being like animals who have to gnaw off a limb to get out of a trap.  These are mean streets, "vivid, killing streets" (7). And whether one stays on the rocks and is subjected to the stormy and rough waves or tries to get off the rocks and leave, it's a very risky business, life-destroying for many.  Reading even a bit more into this passage, I think it also conveys an image of a good place for a shipwreck, running aground these rocks, with sailors lost, a ship destroyed, and no means of getting away.  Anyone who has been placed in a project like this could very well feel shipwrec...

The story in A Christmas Carol is designed to get the reader thinking.  Here are some of the most significant quotations about Scrooge’s journey from miser to family man. One of the most important quotations is from Scrooge’s conversation with the man who comes asking him to donate money for the poor.  Scrooge’s reaction is not just to say no, but to say that the poor should go to prisons and workhouses.  “… I don’t make merry myself at Christmas and I can’t afford to make idle people merry. I help to support the establishments I have mentioned—they cost enough; and those who are badly off must go there.” “Many can’t go there; and many would rather die.” “If they would rather die,” said Scrooge, “they had better do it, and decrease the surplus population. …” (Stave 1)  This is Scrooge at his most horrifying, when he suggests that the poor are better off dead because they are “surplus population.”  Scrooge is putting himself above the poor, which the Ghost of Christmas present chides h...

I suppose there are no other radioactive elements in the sample, and that the results of bismuth-210's decay are not radioactive. Then the activity level is proportional to the remaining quantity of bismuth-210. Then denote the half-life of bismuth-210 as `H` days (we select days as the units of measure for convenience, because the given time is in days). Then after `H` days a half of the initial activity remains, after `2H` days a quarter of initial activity remains and after `x` days `1/2^(x/H) = 2^(-x/H)` remains. This is true for any `x.` It is given that for `x=15.6` days 11.6% = 0.116-th part remains, so `2^(-15.6/H) = 0.116.` Take the base `2` logarithm of both sides and obtain `-15.6/H = log_2(0.116),` or `H = -15.6/log_2(0.116)=-15.6 (ln(2))/(ln(0.116)).` Here we used that `log_2(a) = (ln(a))/(ln(2)).` In numbers it is about   5 (days) .

Hope Yancey is the main character in Hope Was Here .  She is a teenage girl who lives with her aunt.  Hope is an adaptable person.  She adapts to all the changes and moves in her life.  The most steady thing in her life is her aunt, who raised her.  G.T. becomes like a father to her after he and her aunt marry.  Hope and her aunt go to work at G.T.'s diner.  She meets Braverman, who works at the diner.  She likes him.

The original Thirteen Colonies were founded as extensions of British territory for the purpose of cultivating and processing resources which might be valuable overseas and in the New World. Many people fled to the Colonies to escape religious persecution in the Old World, or to seek wealth. Though the Thirteen Colonies were founded for similar reasons, we divide them into three regions based on their geography, climate, and the resources they capitalized on.  The New England Colonies of Massachusetts, Connecticut, Rhode Island, and New Hampshire specialized in fishing, whaling, shipbuilding, and lumber. The winters were hard here and many foods and goods had to be imported from the Middle and Southern Colonies or overseas. The Middle Colonies of New York, New Jersey, Pennsylvania, and Delaware also provided lumber, but this was not their greatest resource. Iron ore and coal were very important (and profitable) products, and ample farmland meant that staple crops like wheat could be gro...

Dog Whistle Politics: How Coded Racial Appeals Have Reinvented Racism and Wrecked the Middle Class addresses numerous aspects of racial tensions in the United States as they relate to the actions (or inaction) of those in positions of political power, including President Obama. What are the author’s criticisms of Obama’s policies during his first term? In Chapter 9, the author focuses on what he terms President Obama's post-racial strategy. He explains his views that Obama "sidestepped" the issue of race with his first-term policies, thus tacitly reinforcing the so-called dog whistle politics being perpetuated by Republican politicians and many Democrats. Haney-López's primary argument is that by not doing enough to address the issues underlying dog whistle politics in his first term, Obama himself became complicit in reinforcing that narrative. Throughout the book, the author takes the view that if someone is in a position of power, he or she has the responsibility ...

The arrow on the DNA molecule in the image shows the hydrogen bond between complementary nucleotides. DNA stands for deoxyribonucleic acid. This definition is important because it gives away the structure. The three main components of DNA are a base, phosphate, and sugar. A single unit of DNA is called a nucleotide. Every nucleotide has the same kind phosphate and sugar type. The base is what distinguishes one nucleotide from another. The backbone of the double helix structure is composed of both the phosphate and the sugar. The sugar is called deoxyribose, and the phosphate is `PO_4^-3` . On the image attachment, this is represented by the pentagons and circles at the top and bottom. The pentagons represent deoxyribose molecules and the circles represent phosphates. The two strands of DNA are connected by the bases in the middle. There are four bases: adenine, cytosine, guanine, and thymine. Adenine only bonds with thymine and cytosine only bonds with thymine. In the image attachment...

Many characters manipulate each other in order to make personal gain. Reverend Parris, whom we first meet in Act I, seems to care more about his reputation than about the well-being of anyone in Salem, including his daughter, Betty. When the audience first hears that the girls were dancing in the woods, it is clear that Parris intends to manipulate the information to take any blame or suspicion away from himself. His first, most egregious act of manipulation is to essentially force his slave, Tituba, to confess to witchcraft (Act I) so that the blame is removed from his daughter and niece so that no one might suggest he allows such actions in his household. While Parris is more concerned with damage control—that is, making sure that the events do not hurt his reputation—Thomas Putnam takes advantage of the situation and uses the accusations to take revenge on those he believes have wronged him. In Act I, Miller says that because of his “many grievances… it is not surprising to find tha...

European colonies in the Americas varied in many important aspects. The only real similarity between the three countries colonial ambitions is that they were all done to make a profit for the motherland. The Spanish, as the first to breach the New World, attempted to loot the continent of its silver and gold. It did this by attempting to enslave the native populations and then conquering them. All three countries were able to weaken the Native Americans with a variety of germs for which the natives had not built up an immunity. After the Spanish conquered the lands from the indigenous people, they worked hard to acculturate and proselytize them to become Spanish. A complete new ethnic group of mixed Spanish-Indian descent emerged in Latin America as a result of this process (mestizo).   The English attempted to establish colonies in the Americas that produced cash crops. A cash crop is generally a non-food item like cotton or tobacco and is marked by a lack of variety in farming. The E...

In A Christmas Carol , Tiny Tim represents the importance of charity in Scrooge's Victorian society. Tiny Tim is the son of Scrooge's employee, Bob, and suffers from a medical condition which has left him crippled and weak. In Stave Three, Tim is portrayed as a kind-hearted and humble little boy with a strong sense of Christian morality, as we see through his father's observations: "He(Tiny Tim) told me, coming home, that he hoped the people saw him in the church, because he was a cripple, and it might be pleasant to them to remember upon Christmas Day who made lame beggars walk and blind men see.” Because of the poverty his family endures, Tiny Tim's future seems doomed by the prospect of a premature death, as we see in the fourth stave. But in the final stave, Tim is saved by the charity and friendship of the reformed Ebeneezer Scrooge who becomes a "second father" to him. By portraying Tim in this way, Dickens evokes great sympathy for his character a...

Linear yield questions like this are really just compounding fractions. I like to think of it this way. Lets say you have a recipe for fruit salad, and it calls for cored apples. When you make the fruit salad, you lose an amount, say five percent, of the apple. Then, you decide to use the fruit salad in a jello recipe. In the process, you spill some of the fruit salad, say another five percent. If you take the initial apples at 100%, make fruit salad at 95%, then make the jello at 95%, you can compound the yields. 100%*95%*95%=90.25%. Now with the chemistry, it's the same thing. Just multiply the percentages. 96.2%*91.3%*91.4%=80.3% After the overall reaction, you will have a yield of 80.3%.

You have asked several questions in the post. I will answer the first one. There were several problems with the plan of government created by the Articles of Confederation. One problem was that the government didn’t have the power to tax. This made it difficult for the government to get money and pay our debts. In the Constitution, the government was given the power to tax. Additionally, under the Articles of Confederation, both state governments and the federal government could make money. This led to a high rate of inflation. Under the Constitution, only the federal government can make money. Another problem with this plan of government is that it couldn’t require people to join the military. When other countries, especially Spain and Great Britain, began to push the United States around, there wasn’t much the US government could do, in part because it couldn’t make people join the military. Along with this issue, the government had trouble maintaining order. When Shays’ Rebellion oc...

The Cunninghams are a poor farming family who live in the northern part of Maycomb County called Old Sarum. Despite the fact that they are extremely poor, the Cunninghams are respectful, honest individuals. They refuse to take anything that they cannot pay back and are trusted throughout the community. Walter Cunningham, Jr. is a kind, shy boy in Scout's class and his father gets along with Atticus. Although the community members respect the Cunninghams, they are known to get drunk and cause havoc occasionally. In Chapter 15, Walter Cunningham and the Old Sarum bunch attempt to lynch Tom Robinson. Fortunately, Atticus refuses to leave the scene, and Walter is able to see the error in his decision making. The next day, Atticus explains to his children that Walter Cunningham is still a good person and that he was influenced by mob mentality the previous night. Overall, the Cunninghams are resourceful, trustworthy individuals who try their best to make ends meet.

The number of moons varies from planet to planet. While some planets do not have any moons, others have many moons. Also note that several moons in our solar system are yet to receive official confirmation, while the rest are confirmed moons (and have names).  Mercury has 0 moons. Venus has 0 moons. Earth has 1 moon and we call it the Moon. Mars has 2 moons: Phobos and Deimos. Jupiter has more moons than any other planet of the solar system. It has 67 moons, of which 53 are confirmed moons and 14 are awaiting official confirmation. Some of the famous moons of Jupiter include Io, Ganymede, Europa and Callisto. Saturn has 62 moons, of which 53 are confirmed, while the remaining 9 are awaiting official confirmation. Titan is the most famous moon of Saturn. Uranus has 27 moons. Neptune has 14 moons, including one moon which has yet to receive official confirmation.  Pluto, which is no longer a planet, has 5 moons. Pluto is now considered a dwarf planet. Ceres, another dwarf planet, has 0 m...

The work of the cowboys was not glamorous. Movies do a disservice to the cowboys because they had to work very hard, no matter what the season was. The movies made it look like the cowboys had a fun and a glamorous life. That simply wasn’t the case. The first issue facing the cowboys was if they would remain employed during the winter. Some cowboys weren’t retained during the winter months. Cowboys, if they remained employed, did have some jobs to do in the winter. The cowboys who remained on the ranch in the winter had to tend to various jobs on the ranch. They needed to be sure that the cattle were safe. The cattle could wander away if they weren’t closely watched. There also was some concern about cattle being stolen. It was the job of the cowboys to watch over and keep the cattle safe. Those cowboys who remained on the job were busy during the winter months.

This might seem like something from a science fiction story. But there is actually strong evidence that plants respond to sound. In one intriguing study, researchers recorded the sound of a caterpillar eating the leaves of a potted plant (species  Arabidopsis thaliana).  Then they played the recording back to other plants of the same species and measured changes in the chemical composition of the leaves. Compared to plants in a control group, plants subjected to the sound recordings subsequently produced elevated levels of chemical defenses in their leaves -- chemicals that deter predation by caterpillars and other natural leaf predators. The researchers also tested the effects of other vibrations -- (1) the vibration produced by the wind (recreated by aiming a fan at the plants), and (2) the "vibrational mating song of a leafhopper" (presented via audio playbacks). The scientists matched the amplitude of these alternative vibrations so they overlapped with that of the chompi...

On the French coast the light Gleams and is gone... Arguably, this light symbolizes hope and connection with the rest of the world. It appears for a moment, inspiring hope, then dissolves in the distance. "Dover Beach" is a poem that taps into an existential anxiety that will become more pronounced after World War I. Arnold's narrator anticipates the existential crisis of the Modernist age. The third stanza, beginning with "the Sea of Faith" is important as well. Religion, which provided meaning in an otherwise incoherent world, is fading in power and strength, "retreating, to the breath / Of the night-wind." The coastal setting is significant. In literature, coast lines are the borders between the known world and the Unknown. It is the the line between the firm, stable land on shore vs. the mobile and violent sea. In the final stanza, in response to this hopelessness and uncertainty, the narrator turns to his/her love. Companionship is one's only ...

Kevin and Maxwell are friends who find a way to survive life as misfits by joining forces. Kevin suffers from birth defects that affect his ability to walk without crutches. Max, on the other hand, can walk just fine, but he is very tall for his age and feels like he doesn't fit in because he towers over everyone his age. Also, Kevin is highly intelligent and Maxwell is in the learning disabled classes. Together they find a way to forge their way through physical and intellectual trials together. Max hoists Kevin on his shoulders so they both can get around more easily and Kevin helps Max with reading and writing. People around them have never seen a partnership like this before, though. Their reactions are similar because both groups are amazed and excited when they see Kevin sitting on top of Max's shoulders. First, in Chapter 11, Kevin and Max meet Loretta and Iggy in the Testaments. The boys went there to give Loretta her wallet that they found. When she sees them, she tell...

To apply the  Root test  on a series `sum a_n` , we determine the limit as: `lim_(n-gtoo) root(n)(|a_n|)= L` or `lim_(n-gtoo) |a_n|^(1/n)= L` Then, we follow the conditions: a) `Llt1` then the series is  absolutely convergent . b) `Lgt1` then the series is  divergent . c) `L=1` or  does not exist   then the  test is inconclusive . The series may be divergent, conditionally convergent, or absolutely convergent. In order to apply the  Root Test  in determining the convergence or divergence of the  series  `sum_(n=1)^oo n/4^n` , we let : `a_n =n/4^n` . Applying the Root test, we set-up the limit as:  `lim_(n-gtoo) |n/4^n|^(1/n) =lim_(n-gtoo) (n/4^n)^(1/n)` Apply Law of  Exponents: `(x*y)^n = x^n*y^n` and `(x^n)^m = x^(n*m)` . `lim_(n-gtoo) (n/4^n)^(1/n)=lim_(n-gtoo) n^(1/n)/ (4^n)^(1/n)`                        ` =lim_(n-gtoo)n^(1/n)/ 4^(n*1/n)`                        ` =lim_(n-gtoo)n^(1/n)/ 4^(n/n)`                        ` =lim_(n-gtoo)n^(1/n)/ 4^1`                        ` =lim_(n-gtoo)...

Tom Benecke's character trait of perseverance directs his persistence in completing his project for grocery stores, as well as later on affecting his determination to catch up to his wife at the theater.  When Tom's wife leaves to go to the movies alone because Tom insists on staying home in order to finish his project, her departure through the front door creates a draft, and the yellow sheet on which he has recorded data gleaned from long weekends of work is drawn outside, landing on the ledge not far from the window. Tom casts a long look at the piece of paper, realizing no broom or other object will reach the yellow paper. It was hard for him to understand that he actually had to abandon it—it was ridiculous—and he began to curse. Of all the papers on his desk, why did it have to be this one in particular! Tom just cannot give up on the yellow sheet; therefore, he goes out onto the ledge in order to retrieve this valuable sheet of paper, risking his life in the process of t...

For the most part, the powers of Congress are formal powers.  The Congress is the only branch that has the power to propose bills and to pass them so they can become law.  The Senate (one branch of Congress) has the power to confirm or reject people that the president nominates for the Supreme Court or for various other high government offices.  Both houses together have the power to override presidential vetoes and to propose constitutional amendments.  These are all very formal powers and it is the formal powers that make Congress extremely important in our system. Congress (or individual members of Congress) has very little in the way of informal powers.  Congress has some informal power over the president’s agenda.  A president might change his (or someday her) agenda because he knows that Congress will never pass the laws he really wants.  The same is true of people that the president appoints.  President Obama nominated a fairly moderate person to the Supreme Court after Justice ...

When the Hispaniola  reached Treasure Island, Long John Silver appeared to believe that Captain Smollett was about to show him the actual map of the island, the one that Jim had found in Billy Bone's personal effects. Silver became quite excited at the prospect, but then he appeared to be equally as disappointed when he realized that the chart he was being shown was a reproduction of the map, not the map itself. The reason that this turn of events seemed to disappoint Silver so much was because the actual map contained the instructions, written by the late Captain Flint, for finding the buried treasure on the island. Had Silver been able to see the map and memorize the instructions for finding the treasure, he and the pirates would have been able to set off after the treasure immediately upon landing on the island. They would not have needed to depend on the Englishmen leading them to the treasure, which was Silver's original plan, nor would they have needed to fight the Englis...

Before 1900, Germany's relations with the United States were marked by large-scale German migration to the U.S., including during the colonial period and continuing into the 1800s. Many Americans trace their ancestry at least partly back to Germany, and, even today, Germans are the largest ancestry group in the U.S. (as reported to the Census Bureau). In the late 1800s and early 1900s, Americans regarded Germany as a model of scientific and medical education, and many Americans went to Germany for medical and scientific training. In addition, German culture, including its language, music, and poetry, was highly regarded in the U.S. After Germany unified in 1871, it began to develop a strong navy and military force that was used to expand its empire. The U.S., while still generally friendly towards Germany, watched its growing expansion towards the Caribbean and elsewhere with some degree of concern. World War I marked a change in German-American relations, as the U.S., after a peri...

One of the morals of the story is that you never know what you are capable of until you try. Harry was faced with extraordinary circumstances, and he was able to rise to the challenge.  He found reserves of bravery within himself, as well as special abilities. Harry Potter had no idea that he was a wizard, of course.  When he was eleven years old, he found out he was a wizard and was whisked off to wizarding school.  That was pretty unusual.  Until then, he had no idea he was “The Boy Who Lived” or that he had famous parents. From the beginning, Harry exhibited traits of bravery and curiosity.  He saw Hagrid take something from a vault at Gringotts, and he wanted to protect it.  He thought that it was Snape who was after it, and about that he was wrong, but at least he tried to protect Hogwarts.  Harry made friends based on their character traits and not prestige.  He discovered that he had talents he never knew he had, including an aptitude to play the sport Quidditch. Harry risked hi...

Helmholtz says that Shakespeare was an excellent propaganda technician, but his society was more interesting so he had more to write about. John, who grew up on a reservation and is referred to as the Savage, loves Shakespeare. It was his emotional lifeline as a child, and it is still the way he interprets the world. He expected to find a brave new world in the modern society, but what he finds is one that opposes everything he believes in and holds dear. "Do they read Shakespeare?" asked the Savage as they walked, on their way to the Bio-chemical Laboratories, past the School Library. "Certainly not," said the Head Mistress, blushing. She is blushing because Shakespeare is considered inappropriate in the society in Brave New World, because the poems and plays’ content and themes are often about love, for one thing. There is no fiction in the school’s library. It is all practical and modern. Shakespeare is relegated to the heathen past when people procreated on thei...

A permanent magnet is one in which the magnetic property is inherent to the material itself, as opposed to being induced by some external action such as an electrical current. Magnetism arises from a sub-atomic property called spin, which has no classical analogue, but can be thought of as being somewhat similar to rotation. The "direction" of the spin matters for a variety of atomic conditions, such as the Pauli Exclusion Principle, which states that the orbitals in an atom can only hold two electrons at a time, and those electrons must have opposite spins. Electrons in different orbitals are allowed to have the same spin. Spin is an electromagnetic property, and if two spins are in opposition to each other, their magnetic effect cancels out. If there are two or more unpaired electrons, however, they will produce a net magnetic effect. Iron is the most common example of a magnetic material, but others such as liquid oxygen can also behave like permanent magnets due to these ...

Immediately after Mr. White makes the wish for two hundred pounds, three things happen: A fine crash from the piano greeted the words, interrupted by a shuddering cry from the old man. His wife and son ran toward him. His skeptical and fun-loving son Herbert plays a loud chord on the piano, as if to create an effect of something like a magical feat being performed. His father drops the monkey's paw because, as he tells his wife and son, it seemed to twist in his hand like a snake as he made his wish. Throughout the story, it is never clear whether the wishes are being granted by the monkey's paw or they only appear to be granted as a result of coincidence. As far as the paw seeming to twist in Mr. White's hand is concerned, that may have been caused by his fright when Herbert startled him with the "fine crash" from the piano, which was more or less what Herbert intended. After that, nothing happens. The three family members stay up a little while longer and then a...

We must apply conservation of relativistic 4-momentum, `P^(mu)=[E_(t o t)/c,p]` . Where ` p=gamma*mv` is the relativistic spatial momentum. `P_i^(mu)=P_f^(mu)` `P_(i,1)^(mu)+P_(i,2)^(mu)=P_f^(mu)` `[E_(m,t o t)/c,gamma*mv]+[E_(m,t o t)/c,gamma*m(-v)]=[E_( t ot)/c,0]` Notice the first two black holes have the same momentum but are traveling in the opposite direction. The final black hole has no spatial momentum. Setting the spatial components equal to each other is redundant, so set the zeroth energy components equal to each other. `E_(m,t o t)/c+E_(m,t o t)/c=E_(t o t)/c` `2E_(m,t o t)=E_(t o t)` We can use the equation: `E_(m,t o t)=gamma*mc^2` Where `gamma` is the lorentz factor, for the initial black holes it is: `gamma=1/sqrt(1-v^2/c^2)=1/sqrt(1-(0.8c)^2/c^2)` `gamma=5/3` `gamma=1 ` when the object is at rest. `2E_(m,t o t)=E_(t o t)` `2gamma*mc^2=Mc^2` Where M is the mass of the final black hole. `2gamma*m=M` Then the final mass of the black hole M is equal to: `M=2gamma*m=2(5...

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. A common example is sugar water. If you place a sugar cube in a glass of water, the sugar molecules are concentrated at the sugar cube. Over time, the sugar cube decreases in size. That is because the sugar molecules are dispersing through the water. The sugar molecules are moving from where they are highly concentrated (sugar cube) to where there is a low concentration (no sugar in the water). Eventually, the sugar cube will completely dissolve and the sugar molecules will be evenly dispersed in the container of water. Another example of diffusion is a candle burning. When we light a candle, the room will start to smell like that scent. The ingredients used to make the fragrance are concentrated in the candle; this is where the concentration is high. As the candle heats up, particles that smell like the fragrance are released and dispersed into the air. The fragrance diffuses int...

In the story, Delia is loving, loyal, and caring. Delia marries Joe even though she knows that he is a struggling artist. When they experience straitened circumstances, Delia takes a job at a laundry-shop. She doesn't complain but sets to work to earn enough for Joe's art lessons with Mr. Magister. Although Joe feels guilty that Delia is shouldering the financial load in their little family, he cheers up when he hears that Delia has found a paying piano student. Delia tells Joe that her new student is a little girl named Clementina. Accordingly, she is the daughter of one General A. B. Pinkney, and the Pinkneys appear to be a wealthy family. Of course, none of what Delia tells Joe is true. She tells a white lie because she wants to spare Joe the humiliation of knowing that his wife is supporting him financially. In the end, Joe discovers what Delia has really been doing when she accidentally injures her hand at the laundry-shop. Ironically, it is Joe who sends up the "cott...

When General Zaroff explains to Rainsford why he feels justified in hunting men he is echoing the Social Darwinian theories of the late 19th and early 20th centuries. Social Darwinists used the biological theories of Charles Darwin to claim that certain elements of society were inferior to others. They focused on Darwin's idea of natural selection and argued that since they were the fittest and the strongest they could basically do whatever they liked. Zaroff makes it clear that, because he grew up the rich son of Russian nobility, he believes himself to be superior to the men he hunts: "Life is for the strong, to be lived by the strong, and, if needs be, taken by the strong. The weak of the world were put here to give the strong pleasure. I am strong. Why should I not use my gift? If I wish to hunt, why should I not? I hunt the scum of the earth: sailors from tramp ships—lassars, blacks, Chinese, whites, mongrels—a thoroughbred horse or hound is worth more than a score of the...

In Housman's poem, a young man of twenty enjoys the snowy white beauty of the cherry bough in bloom in spring. Yet at the same time, he laments how brief life is. Even if he lives to seventy, which he considers his full life span, he will only have fifty years left to see the cherry bough in bloom. Fifty years might seem a long time until we remember that the cherry tree blossoms in all its glory only for a brief time each year. The ephemeral or short-lived quality of the cherry's blooms represents or becomes a metaphor for how brief life itself is. Blink your eyes and it is over. Life is beautiful but it speeds by too fast. The poet is sad about this, but his acute consciousness of life's brevity means he will make time to go to the woodlands to see the cherry tree. He understands he needs to make the most of the time he has, and the poem prods the rest us to be just as alert to how short life is, so that we too can fully enjoy its beauties. 

Schlafly believed that the Equal Rights Amendment (ERA) would harm women. As she wrote, "Why should we lower ourselves to 'equal rights' when we already have the status of special privilege?" She thought that the passage of the ERA would make women subject to harsh realities that men have to face, such as the draft. In addition, she thought that the ERA would get rid of a women's right to alimony and child support and would instead establish a woman's right to these supports based only on her income. As the law stood in 1972 when she wrote this document, a man was always required to support his wife and children. Schlafly felt the ERA would interfere with these provisions and would instead force a woman to find a job to support her family. She also believed that the ERA could interfere with the custom by which women are always awarded custody of their children in the case of divorce. Finally, Shlafly felt that women's "libbers," as she calls them...

We are asked to show that `csc^2(pi+pi/6)=(-csc (pi/6))^2 ` : First, the cosecant function has a period of 2pi; that is adding or subtracting multiples of 2pi to the argument leaves the result unchanged. If instead we look at the square of the cosecant function, we notice that the period is now pi units. If you look at the graph of the cosecant function there are parts above the x-axis and below the x-axis. The parts below are a glide reflection of the parts above. Squaring results in all parts of the graph above the x-axis with translational symmetry of pi units. (See graphs.) Thus `csc^2(pi+pi/6)=csc^2(pi/6) ` The cosecant function returns a real value for all inputs in its domain, and for real numbers `(-a)^2=a^2 ` . So `(-csc (pi/6))^2=(csc(pi/6))^2 ` But the notations `(csc(pi/6))^2"and"csc^2(pi/6) ` are interchangeable by convention. Thus ` csc^2(pi+pi/6)=csc^2(pi/6)=(csc(pi/6))^2=(-csc(pi/6))^2 ` The graph of the cosecant function in blue, and the square of the functio...

Bradbury develops the theme of censorship by gradually introducing the ways in which society chose to neglect literature and the government's reasons for censoring intellectual thought. Initially, Bradbury describes how the government decided to censure knowledge by destroying books. As the novel progresses, Captain Beatty explains to Montag how society's wish for immediate entertainment and the population's distaste for criticism led to the censorship of books. Essentially, the dystopian society sought to eliminate any type of uncomfortable discussion regarding their lives. As the novel progresses, Montag reaches out to Faber who explains to him the significance of books. Through their conversations, Bradbury examines the dangers of censorship. Montag eventually escapes the authorities and joins a band of traveling intellectuals who find a way to avoid censorship regulation by remembering novels. Overall, Bradbury gradually examines the theme of censorship by exploring ho...
