Question

Power is a measure of the... d. 1) the rapidity with which work is done (ii) amount of energy required to perform the work iii) The slowness with which work is performed (iv) length of time

Answer 1

amount of energy required to perform work

Answer 2

Explanation:

(i) rapidity with which work is done .

(ii)slowness with which work is done.

( both are correct alternatives.)

Reason:energy means the how much work is done & power means how much fast work is done.

E=p/t. so

P=e/t , (P is also =work/time)

E=W because energy is the measure of work done

E=energy, P=power, T=time.

I hope this may help you .
