Q
Q: A machine does 1500 J of work in 30 seconds. What is its power output?
Solution:
Power (P) = Work (W) / Time (t). P = 1500 J / 30 s = 50 W.
Steps: 5
Show Steps
Step 1: Identify the work done by the machine, which is 1500 Joules (J).
Step 2: Identify the time taken to do the work, which is 30 seconds (s).
Step 3: Use the formula for power, which is Power (P) = Work (W) / Time (t).
Step 4: Substitute the values into the formula: P = 1500 J / 30 s.
Step 5: Calculate the power output: 1500 J divided by 30 s equals 50 Watts (W).
