Which sentence BEST states the central idea of the first paragraph of "Roller Coaster Physics"?

A. Potential energy is created by the lift hill.

B. Gravity is the force that makes roller coasters possible.

C. Kinetic and potential energy work together to power roller coasters.

D. Potential energy builds as a train car goes up the lift hill, while gravity pulls a train car down the tracks.

Answers

Answer 1

The first paragraph of "Roller Coaster Physics" shows the main idea that the potential energy increases as the roller coaster climbs the hill, while gravity pulls the roller coaster along the tracks.

We can arrive at this answer because:

"Roller Coaster Physics" is an article that wants to show you how a roller coaster works.The first paragraph makes it clear how gravity and potential energy play a role in the functioning of the roller coaster.This is because, in the first paragraph of the article, we can see that the moment the roller coaster is going up the hill is the moment it is building a reservoir of potential energy.This energy will be transformed into kinetic energy when the roller coaster starts going downhill.However, what pulls the roller coaster downhill is gravity.

With this, we can see that the higher the roller coaster can go, the more potential energy it accumulates and the greater the intensity of gravity on it.

日 what language feature is "it seized the frail Craft (line 13) an example of ?

Answers

In the story, "The Boy who was Afraid" by Armstrong Sperry, we learn of Mufatu's fear of the sea. In describing the hurricane that crashed his mother's canoe, the author used the line;  "it seized the frail Craft". The language that is used in this line is personification.

Personification is the description of inanimate things with the attributes of humans. The craft is described as frail.

Normally, it is humans who assume a frail form due to sickness or other conditions. The description of the craft as frail shows that it was now weak.

The hurricane seizing the craft is also another form of personification because the hurricane has no hands to seize the craft.

Summarily, the language form used here is personification.

Metaphor. There is no like or as making it a metaphor

The Figure of Speech in the sentence "The black cat screeched and howled at the harvest moon"  is Metaphor.

What is a Metaphor?

A comparison between two objects that are otherwise unconnected is known as a metaphor.

With a metaphor, the characteristics of one item are metaphorically applied to another. I use attributes associated with one thing—the urgency and helplessness of drowning—to express meaning for another thing—the work I need to get done—when I say, "Dude, I'm drowning in work."

There are metaphors everywhere. A couch potato, he is. She has a pure heart. That gathering was amazing. The source of all evil is money.

Metaphors can add originality and clarity to literature and ordinary conversation by comparing two unrelated ideas, allowing us to view situations from new perspectives. For example, H.P. Lovecraft wrote, "We exist on a placid island of ignorance in the midst of black oceans of infinity, and it was not meant that we should go far." He employs vivid imagery to illustrate the boundaries of human understanding.

The quote from the text that best supports the answer to Part A is "When you're behind bars, you believe that no one even knows that you exist anymore" (Chapter 13). So the correct option is D.

This quotation supports the response to Part A, which requests proof of the ways in which the experience of being imprisoned might impact one's sense of identity and worth. Wes Moore discusses in the text how feeling forgotten and invisible while incarcerated affected him.

He thought no one even knew he existed or gave a da'mn about him. This demonstrates how being imprisoned can negatively affect a person's sense of identity and self-worth. It bolsters the notion that incarceration can cause a person to feel alone and cut off from the outside world.

Overall, this quotation is a good illustration of how being imprisoned may change how someone sees themselves and their place in society. It serves to underline the notion that incarceration can significantly alter a person's identity. So the correct option is D.

The circumstances surrounding Lincoln's death remain somewhat unclear.
O Bands of Lincoln assassination enthusiasts speculate about why Americans aren't interested in their past.

Answers

Answer:

The circumstances surrounding Lincoln's death remain somewhat unclear.

Explanation:

We can use the process of elimination to find the truest inference out of the inferences given to us.

"Lincoln assassination enthusiasts have contributed meaningfully to research on his death."

The passage provided contains nothing about the assassination enthusiasts possessing research on his death. It only says, "There continue to be bands of Lincoln assassination enthusiasts who find it iresistible to speculate about what did or did not happen those fateful days in the spring of 1863."

"During the spring of 1865, experts unearthed new facts about Lincoln."

The passage states, "There are few if any  decisive new facts remaining to be unearthed." This means that experts are still trying to find solid facts about him, let alone facts about Lincoln himself. Experts are clueless about Lincoln, so unearthing any bit of information about him is most likely rare. And even if they did find any information on him, they wouldn't be certain if it wouldn't be solid.

"Bands of Lincoln assassination enthusiasts speculate about why Americans aren't interested in their past."

In the passage, it solely includes, "For a country said to be uninterested in its past, this would seem to be a giant exception to the rule." It does not inform us that the "Bands of Lincoln assassination enthusiasts" directly does this, nor does it imply anything about Americans.

Therefore, inference is the third option.

I hope this helps you in any shape or form.

The circumstances surrounding Lincoln's death remain somewhat unclear the inference you can make based on the underlined portion of the text. The correct option is C.

Why was Lincoln's assassination so important?

The Reconstruction era was significantly altered by the death of Abraham Lincoln. Confederate General Robert E. Lee's army surrendered at Appomattox Court House, bringing an end to the four-year War Between the States, just five days before President Abraham Lincoln was assassinated.

Actor John Wilkes Booth assassinated President Abraham Lincoln by entering the presidential box at Ford's Theatre in Washington, D.C., on April 14, 1865. Booth leaped onto the stage and fled through the back door as Lincoln sagged forward in his chair.

Thus, the ideal selection is option C.
