Which property describes the amount of energy that flows past a given area per unit of time?

Intensity is defined as rate of energy per unit area.

Explanation:

As we know that intensity of wave is defined as the energy of wave passing through a given cross-section per unit time.

so it is defined as

we can also define it as power per unit area

so here we can solve it further and find that intensity is given as

so on increasing the intensity of wave, we will have more amplitude.

So the above property is defined as intensity.

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
