Q
Q: If a machine does 500 Joules of work in 10 seconds, what is its power output?
Solution:
Power is calculated as work done divided by time taken. Here, Power = 500 J / 10 s = 50 W.
Steps: 7
Show Steps
Step 1: Understand that power is the rate at which work is done.
Step 2: Know the formula for power, which is Power = Work / Time.
Step 3: Identify the work done, which is 500 Joules.
Step 4: Identify the time taken, which is 10 seconds.
Step 5: Plug the values into the formula: Power = 500 J / 10 s.
Step 6: Calculate the result: 500 divided by 10 equals 50.
Step 7: Conclude that the power output is 50 Watts.
