Questions & Step-by-Step Solutions
A motor has a power rating of 1500 Watts. How much work can it do in 10 minutes?
Step 1: Understand that power is the rate at which work is done. The motor has a power rating of 1500 Watts.
Step 2: Convert the time from minutes to seconds. Since there are 60 seconds in a minute, multiply 10 minutes by 60 seconds to get the total time in seconds: 10 × 60 = 600 seconds.
Step 3: Use the formula for work done, which is Work = Power × Time.
Step 4: Substitute the values into the formula: Work = 1500 Watts × 600 seconds.
Step 5: Calculate the work done: 1500 × 600 = 900000 Joules.
Power and Work – Power is the rate at which work is done, and work can be calculated by multiplying power by time.
