Question

If an engine does 200 J of work in 100 s, how much power was generated?A. 2000 WB. 20 WC. 2 WD. 200 W

Answer 1

ANSWER:

C. 2 W

STEP-BY-STEP EXPLANATION:

Given:

Work (W) = 200 J

Time (t) = 100

The power is given by the following equation:

$\begin{gathered} p=\frac{W}{t} \\ \\ \text{ We replacing:} \\ \\ p=\frac{200}{100} \\ \\ p=2\text{ watts} \end{gathered}$

Therefore, the correct answer is C. 2 W
