Which is the equation for a machine’s efficiency?(1 point)

Question

Responses

Efficiency=input energy−output energy
Efficiency=input energy−output energy

Efficiency=output energyinput energy . 100
Efficiency=output energyinput energy . 100

Efficiency=input energy+output energy
Efficiency=input energy+output energy

Efficiency=input energyoutput energy ⋅ 100

Answer 1

The correct equation for a machine's efficiency is:

Efficiency = (output energy / input energy) × 100

So, the second option you provided is correct:

Efficiency = output energy / input energy × 100
