Question

1. a machine does 1,500 j of work in 30 seconds. what is the power of this machine? 100 w 50 w 25 w 75 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 \( W = 1500\ J \) and \( t=30\ s \). Then \( P=\frac{1500}{30} \).

Step3: Calculate the power

\( P = 50\ W \).

Answer:

50 W
