<h3>Answer:</h3>

Input work

<h3>Explanation:</h3>

Concept being tested: Efficiency of machines

Therefore we need to know what is the efficiency of a machine

  • Efficiency of a machine is the ratio of work output of machine to the work input expressed as a percentage.
  • Thus;

Efficiency = (Work output ÷ Work input) × 100%

  • Therefore, if the work input is equal to the work output then the efficiency of the machine will be 100%.
  • Most machines are not 100% efficient due to loss of energy in form of heat due to friction of the moving parts of the machine.
