The correct answer is:
$1 \mathrm{~W}$
Given, work done, $W=120 \mathrm{~J}$
Time, $t=2 \mathrm{~min}=2 \times 60=120 \mathrm{~s}$
$\therefore$ Power $=\frac{\text { Work done }}{\text { Time }}=\frac{W}{t}=\frac{120}{120}=1 \mathrm{~W}$
Time, $t=2 \mathrm{~min}=2 \times 60=120 \mathrm{~s}$
$\therefore$ Power $=\frac{\text { Work done }}{\text { Time }}=\frac{W}{t}=\frac{120}{120}=1 \mathrm{~W}$
