Question

1. a motor does 3,000 j of work in 20 seconds. what is the power of the motor? 250 w 100 w 150 w 500 w

Explanation:

Step1: Recall the power formula

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

Step2: Substitute the given values

Given \( W = 5000\ J \) and \( t=20\ s \), then \( P=\frac{5000}{20} \).

Step3: Calculate the power

\( P = 250\ W \).

Answer:

250 W
