Questions & Step-by-Step Solutions

A machine does 300 J of work in 5 seconds. What is its power?
  • Step 1: Identify the amount of work done by the machine, which is 300 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 (P) = Work / Time.
  • Step 4: Substitute the values into the formula: P = 300 J / 5 s.
  • Step 5: Calculate the result: 300 J divided by 5 s equals 60 Watts (W).
  • Power – Power is the rate at which work is done, calculated as work divided by time.
  • Work – Work is defined as the energy transferred when a force is applied over a distance.
  • Time – Time is the duration over which work is performed.
