Solution 1

Sure, let's solve this step by step:

Step 1: Convert the time from minutes to seconds because the power is given in Watts (which is Joules per second). So, 1.0 min = 60 seconds.

Step 2: Calculate the total energy input to the motor in the given time. The power is the rate of energy transfer, so En Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
