Answers

Answer 1

Answer:

A

Explanation:

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.

Answer:

“Knowledge is dangerous. Once you know something, you can't get rid of it. You have to carry it. Always.” - Samantha Shannon In the science fiction novel “Flowers for Algernon'' by Daniel Keys. Charlie a autistic adult, is given a surgery that is supposed to make him smarter. In “Flowers for Algernon'' the surgery has improved Charlie’s quality of life for example: In the short time Charlie was smart he made a major contribution to science, since the surgery made him more emotionally aware Charlie was able to see that he loves Miss Kinnian, and upon his return to Donnegan’s Plastic Box Company he sees that Joe Carp and Frank Reilly truly are his friends.

In the short period of time Charlie was smart he was able to make a major contribution to science. Charlie discovers the effects of the surgery on both him and Algernon. “The unforeseen development, which I have taken the liberty of calling the Algernon-Gordon Effect, is the logical extension of the entire intellectual speed-up. The hypothesis here proven may be described simply in the following terms: Artificially increased intelligence deteriorates at a rate of time directly proportional to the quantity of the increase.”(Progress Report 13 June 5) If Charlie wouldn’t have had the surgery he couldn’t have found this important discovery, which is beneficial information to psychologists and brain surgeons everywhere. Another side effect Charlie discovers is that death is an inevitable outcome of the surgery. “Algernon died two days ago. Dissection shows my predictions were right. His brain had decreased in weight and there was a general smoothing out of cerebral convolutions as well as a deepening and broadening of brain fissures.”(Progress Report 13 June 10) Since the results of the surgery had already been published it is unknown whether or not other surgeons had yet again performed the same surgery, but if his progress reports are read there is a chance nobody would die because of the surgery.

Since the surgery made Charlie more emotionally aware he was able to see that he loves Miss Kinnian. When Charlie asked Miss Kinnian to go to dinner with him he noticed features about her he didn’t see before. “I don’t understand why I never noticed how beautiful Miss Kinnian really is. She has brown eyes and feathery brown hair that comes to the top of her neck. She’s only thirty-four! I think from the beginning I had the feeling that she was an unreachable genius-and very, very old. Now every time I see her she grows younger and more lovely.” (Progress Report 11 April 28) Now that Charlie's mental functioning has improved it has also improved his emotional functioning, so he is now capable of feeling complex emotions such as being ashamed, nervous, or love. Another thing that was worth noting was that the thought of leaving Miss Kinnian made Charlie sad. “ ”You’ll see how different branches of learning are related. There are many levels, Charlie like steps on a giant ladder  that take you up higher and higher to see more and more of the world around you. I can see only a little bit of that, Charlie, and I won’t go much higher than I am now, but you’ll keep climbing up and up, and see more and more, and each step will open new worlds that you never knew existed. (...) The thought of leaving Miss Kinnian made me sad. I’m in love with Miss Kinnian.”

Group of answer choices

Answers

Answer:

Republic

Explanation:

It's not confederate because the confederacy in America promoted black slavery and the philosophes were against slavery and serfdom.

It's not monarchy because in a monarchy it's ruled by an absolute monarch which people don't have much control over, but it's different with an absolute monarchy because there are three branches of power like there is in America and Britain.

It's republic because its a type of ruling of democracy and a bunch of philosophes promoted a republic since as it could help the human society.

What is the economic term for the amount of something available and the demand for goods?

Answers

The term "quantity supplied" refers to the amount of available product. For instance, if a farmer provides 100 bushels of corn, then this is the quantity supplied of corn.

On the other side, the term "quantity demanded" refers to the amount of items people are willing and able to pay for. Both components must be present. If someone is willing to pay for something, but not able to, then this isn't part of the demand equation. Likewise, if they have the money, but don't want the product, then it doesn't make sense to include this as part of demand either.

Explain how the Americans went from lands controlled by European colonizers to multiple independent states

Answers

Answer:

The vast majority of the Americas were controlled by European states until the late 18th century. The only exceptions were a few areas in the extreme geographical points of the continent, like Patagonia in South America, or Northern Canada.

Explanation:

Slowly, people from the Americas began to rebel against the European colonizers. The first were the Americans in the English colonies, who founded the United States. The Haitians in the island of Hispaniola followed soon, rebelling against the French. In the following decades, the lands dominated by the Spanish Empire rebelled, and by 1830, Spain had lost all its former colonies but Cuba and Puerto Rico.

By the end of the 19th century, there were very few colonies in the Americas, mostly small Caribbean Islands, some of which are still colonies.
