Answer:

There's no short answer.

Explanation:

The engines start working by burning fuel, this in turn starts turning the engine blades and the blades suck in air and push it out from the back of the engines. This creates a force that pushes the airplane forward. As the volume of air that goes in and out of the engines increase, so does the kinetic energy the airplane has. At a specific speed, depending a lot of factors such as the weight of the airplane, the length of the wings etc, the force that the moving air provides from beneath the wings surpasses the force of gravity that is applied to the plane, the plane takes off.

I hope this answer helps.

Study the poster showing characters from the movie Star Wars and created by the US Department of Health, Education, and Welfare
svetlana [45]

Answer:

The answer is "The photograph shows fictional film characters, used to 'sell' immunization."

Explanation:

A testimonial is one of the most common and effective advertising techniques. You may notice that the products you've been using are endorsed by either famous celebrities or satisfied customers, giving their feedback about the product. In other cases, some promotional ads use experts' opinions about the product. These are examples of testimonials.

<em><u>In this case, the US Department of Health, Education, and Welfare use Star Wars' characters to sell the idea of immunization. </u></em>

<em><u /></em>

In 1977, the first installment of Star Wars was released, and it was a certified box office. The irony illustrates that the two characters were not human beings, but they're warning humans regarding immunization. It may sound funny, but people bought it. And it's because of the characters in the poster.

R2D2 and C3P0 were the characters used in the poster who played supporting but remarkable roles in the movie franchise. The creators of the poster took advantage of how famous these two were and cited as likeable sources since many people loved them.

Identify examples of the following rhetorical strategies in paragraph 13, and explain their effect___________.
ANEK [815]

Answer:

The answers are explained below. Paragraph 13 isn't available.

Explanation:

A rhetorical question is a question asked to create a dramatic effect or to make a point rather than to get an answer, for example <em>Is the pope Catholic? </em>or <em>Can fish swim?</em>

Sentence variety refers to varying the length and structure of sentences in a composition to avoid monotony. Pacing is a stylistic device that shows how fast a story unfolds. Both can help the writer add emphasis to a specific part of the composition.

An analogy is a type of comparison between two things, usually to explain something, i.e. "as light as a feather."

An allusion is an expression to call something to mind, but it is not mentioned explicitly, for example, <em>Don't be a Romeo</em>, in reference to Shakespeare's "Romeo and Juliet."

An imperative sentence gives instructions or advice and expresses a suggestion, command, order, or direction. For example <em>Don't do that!</em>

Aleksandr [31]
Correction!!! I read this over a few more times and I think it is the fourth one because it says "words that were once considered slang are now words of full, legitimate standing in our language." It's talking about the the past tense and present tense of slang. So sorry for the confusion
