The girl in the picture is at the highest point in swinging and starts to come down. Which statement best describes the changes

in energy as she begins to descend?.

SpyIntel [72]2 years ago

When she descends the potential energy will decrease at the same rate that the kinetic energy increases.

<h3></h3><h3>How to describe changes in energy?</h3>

We know that we can write the total energy of a moving object as:

E = U + K

Where U is the potential energy and K is the kinetic energy.

In the given case, U will only depend on the height of the girl and it will be maximized when the height is maximum.

K = (1/2)*m*v^2

where m is the mass and v is the velocity.

When the girl is at the highest point, the velocity becomes equal to zero. This happens because at that point she stops going up and starts going down, so the velocity must be zero at that moment.

Then we have K = 0.

E = U.

As she starts going down, the velocity starts increasing and the height decreases, thus, the kinetic energy increases and the potential energy decreases. This relates to the conservation of energy. E will always be the same value, but K and U will depend on the position of the girl.

This means that if the potential energy decreases a quantity e', then the kinetic energy must be increased by that same amount.

Orlov [11]

The above question wants to assess your writing ability, therefore it is not correct for me to write the thesis statement for you, but I will show you how to write it.

First, you should know that a thesis statement is a short, direct, and objective paragraph that shows your opinion or position on a particular issue.

This opinion must be substantiated by evidence taken from research sources, for this reason, you should read the sources that have been presented to you or research articles, essays, and publications on the subject.

After that, you can answer your question as follows:

  • Present your thesis statement, that is, present your opinion on the future role of zoos.
  • Show information from the research sources that support your thesis statement.
  • Explain how this information supports your opinion and shows it to be true.

An example of a thesis statement would be: According to the reading, the function of zoos will become increasingly obsolete due to the growth of environmental awareness and animal rights.

A story with multiple narrators will usually have a(n) ____________ plot.
Soloha48 [4]

Stories could either have a single or multiple narrator(s). Hence, stories having multiple narrators would usually have a non-linear plot.

  • Multiple narrators in a story means that characters in the story are numerous, hence, acts and scenes would have to be passed on to these characters from time to time.

  • As for single narrator, this is not the case as the number of actors are very limited.

Hence, because multiple narrators often hinders a story to be chronologically ordered, then it would result in a non-linear plot.

:Drag the correct labels to the box. Not all the labels will be used.
Igoryamba
I would say there are three correct answers: exaggerated character behavior, an improbable, absurd storyline, and over-the-top dialogue.
Every character in the play is exaggerated, meaning that they are exhibiting behavior unlike actual human beings. The storyline is improbable because the characters are constantly fighting (99% of the time) and the only time they stop fighting is when they have to kiss to get married. The dialogues are also over-the-top and absurd.
