Answer:

D. 4x as much

Explanation:

The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.

You can also prove this mathematically. The formula for kinetic energy is

\frac{1}{2}mv^2

The question says: constant mass so we can ignore that for now.

(1/2) * 10^2 is (1/2) * 100 = 50

for the 20m/s ball it would be

(1/2) * 20^2 = 400 * 1/2 = 200

Once again, you see that it is 4x

How does soil lose its value? A.When the top soil is stripped by wind or water B.When the bedrock is damaged by animals C.When w
Ratling [72]

A) when the soil is stripped by wind or water.. when this happens the soil can be rid of it's nutrients and fertility.. The other options are actually kind of helpful, when the bedrock is damaged by animals (unless you've already set up and everything) it actually helps to till the soil, the water will help to moisten it and make it better or providing life (depending upon the amount of water tht is) and burrowing animals can consist of worms to groundhogs.. depending upon the plans for said soil, It could be helpful with the worms, but the plans could be altered by the groundhog.. but referring to the original question, It definitely  loses it's value when it's stripped by wind and water.
