Question 38

Which equation correctly expresses the force exerted by an engine in terms of its constant power output, the distance moved in the direction of the force, and the time taken?

A

force=power×distance movedtime taken\text{force} = \frac{\text{power} \times \text{distance moved}}{\text{time taken}}force=time takenpower×distance moved​

B

force=power×distance moved×time taken\text{force} = \text{power} \times \text{distance moved} \times \text{time taken}force=power×distance moved×time taken

C

force=power×time takendistance moved\text{force} = \frac{\text{power} \times \text{time taken}}{\text{distance moved}}force=distance movedpower×time taken​

D

force=distance moved×time takenpower\text{force} = \frac{\text{distance moved} \times \text{time taken}}{\text{power}}force=powerdistance moved×time taken​
