If one motor has three times as much power as another, then the smaller power motor: A. can do the same work in the same time. B

Dvinal [7]

Answer:B

Explanation:

Given

First motor has three times as much as power as another

Let the power of smaller motor be P

Therefore bigger motor has power 3 P

and we know that energy $E=power\times time$

Larger motor $E=3P\times t=3Pt$

Smaller motor $E=P\times 3t=3Pt$

Therefore smaller motor will do same work if it takes three times the time taken by Larger motor
