Scenario a: 120 j of work is done in 6 s. scenario b: 160 j of work is done in 8 s. scenario c: 200 j of work is done in 10 s. which scenario uses the most power?

They all used the same power.

Explanation:

Power is equal to the ratio between the work done (W) and the time taken (t):

Let's calculate the power used in the three scenarios:

A)

B)

C) tex]P=\frac{200 J}{10 s}=20 W[/tex]

So, the power used is the same in the three scenarios.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
