Question

An electric fan has a power output of 60 W. How much work is done if the fan operates for 120 s?
A. 0.5 J
B. 60 J
C. 120 J
D. 7200 J

Answer 1

$\sf Power=\frac{Work}{Time}$

$\sf 60W=\frac{Work}{120s}$

$\sf 60W \times 120s = Work$

$\sf 7200 W s$

$\sf 7200J$

Your final answer is:

$\bf{\huge{\boxed{7200J}}}$
