a stone is projected up from the ground with velocity of 90m calculate time it takes to travel up and back to the ground.taking g=10

Answers

Answer 1

Answer:

Total time of flight is 18 s.

Explanation:

The projected stone is a projectile, so that the time required is the total time of flight (T).

T = [tex]\frac{2U Sin A}{g}[/tex]

where: U is the velocity of the stone (90 m/s), A is the angle of projection, and g is the gravitational acceleration (10 m/[tex]s^{2}[/tex]).

Then,

T = [tex]\frac{2 *90 sin 90^{o} }{10}[/tex]

  = [tex]\frac{180}{10}[/tex]

  = 18

T = 18 s

The time taken for the stone to travel up and back to the ground is 18 seconds.

Answers

Answer:

I agree.

Explanation:

Free writing represents the free presentation of thoughts and ideas within a text. In this case, an author has the complete ability to gather thoughts, transform them into words and put them on paper without worrying about revising or editing what was written because his thoughts are being expressed freely and outside standards of language and grammar. In this way, we can agree with Elbow's statement, because free writing is an exercise in bringing together the process of producing words and putting them on the page.

Which text structure is used in this passage? Read the passage from "Stalin: A Brutal Legacy Uncovered, which is an informational text about Stalin's atrocities and how he used ambition and fear to rule over people of the Soviet Union. cause-effect O sequence O problem-solution comparison-contrast
Stalin's genocidal record was the product of a ruthless. steely personality hardened by searing hardships in his youth: first, brutal beatings by his alcoholic, dirt- poor father, and later, several rounds of imprisonment and exile—from which he often escaped-following his expulsion from a Russian Orthodox seminary for fomenting a strike of railroad workers. For the 20-year- old Stalin, an outstanding student with top marks in Bible and Church studies, the strike was the first step on a new road-a career of rebellion, crime, and radical politics that eventually made him the unquestioned boss of the Communist Party and of 140 million people in the Soviet Union.

Answer:

cause-effect

Explanation:

According to the passage from "Stalin: A Brutal Legacy Uncovered, the story of Joseph Stalin, the brutal Communist leader of Russia is told.

Cause-effect is the text structure used in the informational text about Stalin's atrocities and how he used ambition and fear to rule over people of the Soviet Union.

This is because, according to the informational text, the cause and effect of what Stalin turned out to be, is explained from his experiences in his childhood and early adulthood.

Based on the introduction, why do you think the author wants readers to know the information she will present in this book?

Answers

Answer:

In the introduction, the author explains that many people have false impressions of what a black hole really is. I think she wants people to know the truth about why black holes are an important part of the universe.

Explanation:

Sample response

In the presentation, the creator makes sense of that many individuals have misleading ideas of what a dark opening truly is. I think she believes that individuals should know reality with regards to why dark openings are a significant piece of the universe.

What is purpose of author?

The writer's purpose is to show the perusers of his recently discovered information.The manner in which she needs to grab the eye of the perusers is by beginning by seeking clarification on pressing issues. She needs to illuminate the perusers about the secrets regarding the dark opening.

This alludes to the goal of the writer while composing and can be compared to the topic by showing that he needs to either illuminate, engage or instruct his perusers.

Henceforth, we can see that the storyteller initially starts by seeking clarification on pressing issues to grab the eye of the perusers before she begins to make sense of what a dark opening is.

The writer's purpose is to illuminate the peruser what she has realized. She needs to get the perusers consideration by getting going with questions.

She maintains that the perusers should be educated about how strange are dark openings. The creators tone appears left. Like she believes the peruser should be similarly as Charmed or left as she is.

The simple present tense is used when an action is happening at the time being or at a regular rate. For example, in the first sentence above, the correct form of the sentence is the present tense because the action is happening currently.

The present continuous tense indicates that the action is occurring presently, at a regular rate and will continue right into the future. The present participle of the main verb which ends with -ing is used. The second sentence is indicative of a present continuous tense because the action is in progress and will continue happening after the statement is made.
