Q
Q: If a machine does 200 J of work in 10 seconds, what is its power? (2022)
Solution:
Power (P) = Work / Time = 200 J / 10 s = 20 W
Steps: 5
Show Steps
Step 1: Identify the amount of work done by the machine, which is 200 Joules (J).
Step 2: Identify the time taken to do the work, which is 10 seconds (s).
Step 3: Use the formula for power, which is Power (P) = Work / Time.
Step 4: Substitute the values into the formula: P = 200 J / 10 s.
Step 5: Calculate the result: 200 J divided by 10 s equals 20 Watts (W).
