Gravity and drag both reduce the maximum altitude that a rocket can reach, increasing the cost of rocket flights. This study hypothesizes that rockets with a smoother surface will experience less drag and reach higher altitudes, given the same thrust as rockets with rough surfaces. To test this hypothesis, three identical model rockets were constructed and given finishes with varying degrees of surface smoothness: roughed with 40-grit sandpaper, unfinished, and glossed. Each rocket was outfitted with B5-4 motors and flown ten times. Flight results support the initial hypothesis, with the roughened-surface rocket reaching the apogee point at the lowest altitude and the glossed-surface rocket reaching it at the highest. In conclusion, the findings suggest that smoother surface finishes can reduce the drag force enough to affect altitude, thereby potentially increasing rocket efficiency and reducing fuel costs. Who is the primary audience?

Answers

Answer 1

Answer:

The primary audience is scientists such as engineers, mathematicians, or physicists.

Explanation:

The primary audience is scientists, especially experts in rocket science. They are the primary audience because the explanation that the speaker is giving to the audience has specific information that only people with knowledge in this field will understand correctly. Besides, the expert is talking about how they prove the hypothesis to be true and the steps that they followed. Only scientists can verify that the performed tests can corroborate the theory. If the speech is for an ordinary audience, the language would not be technical. It would be simpler so that the audience can understand it.

Read the passage about the life of Clara Barton.



Clara Barton was born on December 25, 1821, in Oxford, Massachusetts. As a child, Clara was very shy. She first found her calling while caring for her brother after he fell from a rafter in their barn. Despite the fact that most teachers were still men at the time, Clara became a teacher at the age of 15, as well as one of the first women to work for the federal government at the US Patent Office. In 1881, Clara opened the first chapter of the American Red Cross in the United States and served as its first president. The American Red Cross is a relief organization that offers assistance to victims of such disasters as the 1889 Johnstown Flood and the 1900 Galveston Flood. She served as president for 23 years before resigning amidst claims that money was being mishandled internally.

The Civil War was a bloody war fought between the years 1861–1865. During the war, Clara sought to help the soldiers in any way she could. She collected needed supplies and distributed them to the Union Army. These supplies included items such as food, bedding, and clothing. However, Clara was not content to sit on the sidelines; she often risked her own life to care for soldiers wounded in battle. For these deeds, she was nicknamed the "Angel of the Battlefield.” When the war ended in 1865, Clara worked for the War Department helping in various ways.

Which sentence from the passage contains information that could best be used to create a yearbook page about Clara Barton?

A: “The American Red Cross is a relief organization that offers assistance to victims of such disasters as the 1889 Johnstown Flood and the 1900 Galveston Flood.”
B: “She served as president for 23 years before resigning amidst claims that money was being mishandled internally.”
C: “The Civil War was a bloody war fought between the years 1861–1865.”
D: “However, Clara was not content to sit on the sidelines; she often risked her own life to care for soldiers wounded in battle.”

Answers

Answer:

B

Explanation:

Yearbook as the name implies is a book published once in a year, it consists of all achievement made that year.

The sentence from the passage which contains information that could best be used to create a yearbook page about Clara Barton is "“She served as president for 23 years before resigning amidst claims that money was being mishandled internally.”

Clara's achievement while working with the American Red Cross in the United States and the president of the organization for 23 years before resigning amidst claims that money was being mishandled internally.

She resigned which shows she wasn't sacked is an achievement that can be written in her yearbook.

Therefore, “She served as president for 23 years before resigning amidst claims that money was being mishandled internally.” could best be used to create a yearbook page about Clara Barton.

Explain how a word can be a morphemic noun and a syntactic adverb in the same sentence.

Answers

A morphemic noun, person, place, thing, or idea, is a noun that can have suffix added to make it into an adverb word, which is a word used to describe a verb. In the case of the word "Man," you can use "Man" as a noun, for example "The man sat down." If you add "-ly" to the end, you get "manly", an adverb. "The boy had sang manly."

A Morphemic Noun  (individual, spot, thing, or thought) is a thing that can have an addition added to make it into an intensifier (word used to portray an action word).

On account of "Woman," you can utilize "woman" as a thing (ie The woman ran 5 km ). So together in a sentence, you might have "The women had a feminine walk." "woman ", as the thing, and "Feminine" being the modifier that portrays the action word, "walk".

Thus , the Morphemic Noun can be used to add a word an intensifier and potray an action word.

When dark the path, my life had took

When I was at my lowest low

A rope, a helping hand did throw

And pulled me up, out of the pit

And in the dark, a candle lit

And for my hunger gave me "Bread"

Then quenched a thirst inside my head

This loving servant helped me see

There's so much more to this, than me

By helping me, she showed me love

And led me to the One above

And now, alone, as I reflect

I find a spot of self-respect

That had been drowning in my tears

And had not shown itself in years

Let me through life, now walk, not run

Because the help of this true one

Did set me straight and on my way

And I'll remember day to day

Paul often got lost while he was driving. He was easily confused by street signs and besides, driving was so boring. He liked to distract himself by imagining what the other drivers were thinking. “My mind is like a puppy dog,” he laughed, “always chasing after something new.” Maybe the family in the car next to him was on the run; maybe the truck driver up ahead was transporting something fantastic, like diamonds; maybe the woman driving alone in the car behind him was a future movie star. Or maybe, like him, they were all trying to imagine anything except the road in front of them.

After the valuation, then came the division. I have no language to express the high excitement and deep anxiety which were felt among us poor slaves during this time. Our fate for life was now to be decided. We had no more voice in that decision than the brutes among whom we were ranked. A single word from the white men was enough — against all our wishes, prayers, and entreaties — to sunder forever the dearest friends, dearest kindred, and strongest ties known to human beings.

to persuade readers of the importance of youth activism

Answers

Answer:

The author’s purpose for including these details is:

A. to describe her personal recollections to readers.

Explanation:

In "Warriors Don't Cry" Melba Patillo Beals narrates the true story of the group known as the Little Rock Nine. Beals and the other eight African Americans part of the group were the first black people to attend Little Rock High School, in Arkansas.

This particular excerpt from the story has the purpose of presenting Beals's personal recollections to readers. Notice how she focuses on how she felt, on how the whole experience was new and impressive to her. Even though the book itself speaks of injustice and the importance of activism, this passage concerns Beals's personal experiences, feelings, and thoughts - "My heart raced with fear and anticipation as I observed the process. I was almost hypnotized by the wonder of it all." Therefore, the best answer is letter A. to describe her personal recollections to readers.
