Select the correct answer.
which two factors does the power of a machine depend on?
a. work and distance

b. force and distance

c. work and time

d. time and distance

C

Explanation:

The work of an object is the transfer of energy that occurs when a force makes an object move, for work to be done, something has to move and the motion must be the same direction as the force. Work(joules)= Force(Newtons)*Distance(Meters). Power is the rate at which work is done. The formula for power is: Power(Watts)=Work(J) / time(in seconds). Knowing all this, we can safely assume that the power of a machine depends upon work and time.
