The input power to a motor is 12W. The motor wastes 590 J of energy in 1.0 min. What is the efficiency of the motor?
Question
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.
