Verified Answer :

Power = Work / time
 
           = 12900 J / (3*60)s
 
           ≈ 71.667 Watts


Answer:

71.67 Watts

Explanation:

We know that power is the amount of work that is done per unit of time.

The Power formula is

\(P=\frac{W}{t}\)

W= work (Jules)

t= time (seconds)

The unit of power is watts

\([P]= \frac{J}{s}= Watts\)

Before applying the formula, we must pass the minutes to seconds so that it is expressed in the correct units.

\(3 min.\frac{60s}{1min}= 180s\)

\(P=\frac{12900J}{180s}\)

\(P= 71.67 Watts\)
