Questions & Step-by-Step Solutions

If a machine does 200 J of work in 10 seconds, what is its power? (2022)
  • 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).
  • Power Calculation – Power is defined as the rate at which work is done, calculated by dividing the total work done by the time taken.
