Q
Q: If a machine does 2000 J of work in 5 seconds, what is its power output?
Solution:
Power = Work / Time = 2000 J / 5 s = 400 W.
Steps: 6
Show Steps
Step 1: Identify the amount of work done by the machine, which is 2000 Joules (J).
Step 2: Identify the time taken to do the work, which is 5 seconds (s).
Step 3: Use the formula for power, which is Power = Work / Time.
Step 4: Substitute the values into the formula: Power = 2000 J / 5 s.
Step 5: Calculate the result: 2000 divided by 5 equals 400.
Step 6: Conclude that the power output of the machine is 400 Watts (W).
