a gardener uses 2700 j of work to push a wheelbarrow for 60 seconds. how much power does she use?
a. 45 w
b. 90 w
c. 75 w
d. 60 w

Explanation:

Step1: Recall power formula

Power $P=\frac{W}{t}$, where $W$ is work and $t$ is time.

Step2: Substitute values

Given $W = 2700\ J$ and $t=60\ s$, then $P=\frac{2700}{60}$.

Step3: Calculate result

$P = 45\ W$.

Answer:

A. 45 W
