Answer 2

Given :

Work done (W) = 60 J

Time (T) = 1 min

To Find :

Power of heart

Solution :

We know, the rate of doing work is known as power.

In order to find the power, we need to first convert time into seconds

Time (T) = 1 min = 1 × 60 = 60 seconds

Power (P) = $\frac{Work (W)}{Time (T)}$

                =  $\frac{60}{60}$

                =  1 W

Therefore, the power of heart is found to be 1 W.
