Answer:

<h2><u>The capacity or power to do work/ The ability to do work. </u></h2>

Explanation:

such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another

I hope this help:)

7) An apple falls from the tree and the fall is 1.92 seconds. How high up was the apple?

Sergeeva-Olga [200]

Answer:

Ans 171.875 m(according to the units)

Explanation:

As we know,

to find the distance, we need to use this eqn..

speed = distance/ time

So, time is 1.92 s (as given)

the speed is 330 m/s ( in air speed)

so to find it is easy to find by using this

eqn..

speed =distance/time

330 =distance/1.92

330/1.92 =distance

171.875 = distance

What happens to the wavelength as the frequency of a whale noise changes from

gregori [183]

Wavelength decreases

Explanation:

When the frequency of a wave increases from 200hz to 300hz, the wavelength of the whale noise will decrease.

Frequency is the amount of wave that passes through a point at a particular time. The higher the frequency, the more the number of wave passing a particular point.
The wavelength of a wave is the distance between two successive crest or trough in a wave. The longer the wavelength, the more the separation between a wave crest.
A wave is a disturbance that consistently transmits energy.

When the number of wave passing through a point increases, the wavelength is reducing.

Wavelength and frequency are inversely related.
