When a mass of 350g is hung on a spiral spring which was designed for a maximum load of 200g, what happens?

The spring is designed to take a maximum weight of 200g. At this threshold, the spring reaches its elastic limit when the weight is attached to it and allowed to drop down towards the ground.
The extension (e) in meters (m) of a spring is related to the force (F) in Newtons (N) applied to it and its spring constant (k) in Newtons per meter (N/m) by Hooke's Law
F = k times e
Assuming a gravitational constant of 9.81m/s^2 (that on Earth), the maximum force that can be applied to the spring in question is
F_max = 0.2 kg times 9.81 "m/" s^2 = 1.962 kg "m/" s^2 = 1.962N
When the maximum force the spring can withhold is exceeded, the spring constant of the spring will no longer be the same. The spring is no longer in equilibrium and loses its properties of retraction and elasticity. The tension in the matter that makes up the spring is weakened, some bonds of the matter (perhaps metal or plastic) being stretched beyond a critical threshold.
Being overloaded, the spring might lose its elasticity by bending in one or more of its coils, perhaps so much so that the spring snaps. The spring would not spring back up in the direction of its original starting position before the 350g excessive weight was added, as it would with a weight less than 200g, unless the ground which the weight would drag the spring down towards were also springy.
From the point of view of the 350g weight that is added to the spring, the spring would slow the weight's progress to the ground, counteracting the acceleration due to gravity. Depending on the height of the (originally contracted) spring from the ground, the weight might drop to the ground still attached to the spring, or might drop to the ground severed from part or all of the spring, or might dangle above the ground on the spring as a result of its warping of the spring.

What is your reaction to Zaroff's statement, "We try to be civilized here"?

This statement, which comes while Zaroff and Rainsford are having dinner in the general's chateau, should be considered highly ironic. Even though Zaroff's island is in a remote area off the coast of South America, he prides himself on procuring the finest food and drink, including Russian soup and the best champagne. Zaroff is also, as Rainsford labels him, quite the "cosmopolite." His clothes are made by a premier London tailor, and his reading material includes the works of the Roman emperor Marcus Aurelius (much of Aurelius's work had to do with ethics). During the conversation, Zaroff reveals to Rainsford that he has invented a new type of hunting. He actually hunts the men who shipwreck on the island. This gruesome practice clashes with his seemingly civilized and cultured demeanor. In reality, Zaroff is a sociopathic murderer and is far from civilized. As expected, Rainsford reacts negatively to the general's disclosure:

"I have electricity. We try to be civilized here."
"Civilized? And you shoot down men?"

Although the general attempts to argue that it is his right to hunt men, Rainsford is repulsed and ultimately becomes Zaroff's prey in "The Most Dangerous Game."

Explain clearly what, according to Salarino, would make a person sad in Antonio's position.

In act 1, scene 1, Salarino discusses Antonio's melancholy mood and believes that he can explain why Antonio is upset. Salarino believes that Antonio is worried about his merchant ships that are out at sea. Salarino tells Antonio that he has every right to worry about his ships traveling on the dangerous, unpredictable waters and mentions the numerous trivial things that would remind him that his ships are in danger on an everyday basis. Salarino sympathizes with Antonio's difficult situation and genuinely believes that Antonio is concerned about his valuable ships sinking, which would result in his bankruptcy. However, Antonio mentions that the well-being of his merchant ships does not concern him because his financial situation is quite healthy. After Antonio tells Solanio that he is not heartbroken either, Salarino suggests that Antonio is sad simply because he chooses not to be happy.

In Andrew Marvell's "To His Coy Mistress," what kind of love or qualities of love is the speaker trying to express in the first section of the poem (lines 1-20)?

In the first half of the poem, the speaker is trying to convince the addressee, the "lady," that he would allow their love to grow slowly, naturally, and organically ("My vegetable love") if only they had the time for that. He says he would gladly spend a hundred years praising her eyes, and "an age at least to (praise) every part" of her. He says that she deserves to have all this time ("you deserve this state") and that he would happily dedicate all this time to her, if only they had the time.
However, the speaker's protestations that he would love his lady slowly are really nothing more than a crude trick to convince her to have sex with him. The conditional phrase ("Had we") that begins the poem is very telling, as is the reference to the lady's "coyness." The implication is that she is refusing to have sex with him, that she is being coy. She wants to wait, to get to know him better, and to let their love grown naturally, to a point where she feels comfortable taking the relationship to the next stage. He, however, is clearly impatient. His argument in this first stanza is that he would gladly love and court her for all the time in the world, if they had it, but he implies ("Had we") that they don't have all the time in the world. In the second half of the poem, he tells her more explicitly that, soon, the passions ("instant fires") of their youth will burn out, and her beauty "shall no more be found."
In answer to your question, then, the speaker is not expressing any kind of love at all, but only a lust wrapped up in a crude, cynical argument. He tells his lady to stop being coy, to take advantage of their youthful passions before they are too old to have them, that her beauty will soon fade, and, what's more, that if she doesn't hurry up and lose her "long-preserved virginity," to him, then "Time's winged chariot" will overtake them and turn all of his lust "into ashes."

The first section (lines 1-20) of Andrew Marvell's "To His Coy Mistress" describes an idealized love free from the confines of time or human mortality. The narrator of the poem discusses at length what love might look like if he and his mistress had unlimited amounts of time to develop their affection. The key lines in this first section are "Had we but world enough and time" (1) and "My vegetable love should grow / Vaster than empires and more slow" (11-12), as they illustrate that the narrator yearns for an idealized love in which youth lasts forever and lovers are permitted eons to court one another. 
Marvell later contrasts this idealized love with reality. More specifically, he identifies the fact that youth and life do not last forever, and so he and his mistress are not able to enjoy each other's company forever. Juxtaposed with the reality of finite time, the first section of the poem takes on a rather melancholy tone, as it illustrates the yearning for an impossible love that cannot be realized in the face of human mortality.

How did President Roosevelt help in the Great Depression?

Franklin Roosevelt instituted the New Deal during the Great Depression. It created governmental work projects such as the Tennessee Valley Authority and the Civilian Conservation Corps. TVA created hydroelectricity and flood control for the Tennessee Valley area and the Civilian Conservation Corps assisted with the creation of parks. Both of these projects created jobs where the private sector failed to do so. Roosevelt also created the Agricultural Adjustment Act, which helped farmers by creating price floors for their commodities by buying surpluses and encouraging farmers to create less through cash subsidies. This, along with conservation efforts, helped farmers in the Dust Bowl. Roosevelt also created the Social Security Administration in order to provide aid to the elderly and infirm and also to encourage these people to retire so that younger people could take their jobs.
After his inauguration, Roosevelt created a bank holiday so that the government could study the problem of failing banks more closely. He was influential in the passage of the Securities and Exchange Commission, which looked at unfair trade practices on Wall Street. Roosevelt's administration also passed a form of deposit insurance which insured bank deposits against bank insolvency.
Roosevelt's greatest legacy was his fireside chats in which he encouraged the American people to have faith in the economic systems of the United States. Throughout the Depression the unemployment levels never dropped below ten percent so, while the New Deal did not end the Great Depression, it did provide the people some relief and gave them the feeling that the government cared about the plight of the common man.

Which amendment was the most important to the Anti-Federalists?

The Anti-Federalists were a coalition of powerful politicians, farmers, and ordinary Americans that opposed the idea of a strong central government and therefore opposed the ratification of the Constitution. One main point that the Federalists and Anti-Federalists clashed on was the existence of a Bill of Rights. The Federalists argued that there was no need for a Bill of Rights, as any powers not given to the federal government would automatically be ceded to states and individuals. The Anti-Federalists believed it was necessary to protect states' rights. 
James Madison, a famous politician and a member of the House of Representatives at the time, presented a list of amendments that would put limits on the powers of the federal government. What the Anti-Federalists feared most was a tyrannical central government growing too powerful and dissolving the states. The fact that they were spurning British tyranny in the colonies validated their fear. Out of the amendments listed in the Bill of Rights, the tenth was the most important to the Anti-Federalists. It explicitly states that that any powers not given to the federal government in the Constitution go to the states or the people.

I need an exposition about the important story elements: point of view, setting, irony and symbols. Please help.

"Just Lather, That’s All" is told from a first person perspective. Specifically, it is told from the barber's point of view, meaning that the barber narrates all of the story's events. It could be argued that this offers us a limited perspective because the story is not told from the captain's point of view or from an impartial, third person perspective.
In terms of setting, the story takes place in a barber's shop somewhere in Colombia. The political situation is one of unrest because there is a conflict between the government and a group of rebels.
In terms of irony, we can find an example at the end of the story when the captain reveals that he knew about the barber's plans to kill him. This is ironic because it shows that the Barber's secret desire to kill the captain was not a secret at all.
Finally, the razor functions as a symbol of the barber's dilemma over whether or not to kill the captain. Just as the razor glides back and forth along the captain's skin, the barber's mind flips between his desire to be a good barber and his desire to become a revolutionary hero.
