Which of the following describes the relationship between work and power?

a) as power increases, the amount of workable to be done decreases.
b) as power increases, the amount of workable to be done also increases.
c) as power decreases, the amount of work done does not change.
d) as power decreases, the amount of workable to be done increases.

The answer is B

Explanation:

Work can be defined as the energy that is required to apply a force to an object in order to move it from one point to another. In physics, work = force x distance travelled. On the other hand, Power is the work done per time. In other words, it the rate at which work is done and is determined by using the formula, Power = Work/time. In these relationships, it can be seen that power is directly proportional to the amount of work done, hence as power increases, more work is done.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
