Which is the equation for a machine’s efficiency?(1 point) Responses Efficiency=input energy/output energy ⋅ 100, Efficiency=input energy−output energy, Efficiency=input energy output, energy Efficiency=Output energy/input energy ⋅ 100

Answer 1

The equation for a machine’s efficiency is:

Efficiency = (Output energy / Input energy) ⋅ 100

So the correct response is: Efficiency = Output energy / Input energy ⋅ 100.
