Question

If the heart works 60 joules in one minute. What is its power?

Answer 1

Step 1: Given data

Work done (W) = $60J$

Time taken (t) = $1min=60s$

Step 2: Finding Power

Power, $P=\frac{\mathrm{W}}{t}$ where W = work done and t = time

$$\begin{gathered} P=\frac{60}{60} \\ P=1W \end{gathered}$$

Hence, the power is $1W$.
