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

Question

Responses

Efficiency=output energy/input energy . 100
Efficiency=output energy/input energy . 100

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

Efficiency=input energy/output energy ⋅ 100
Efficiency=input energy/output energy ⋅ 100

Efficiency=input energy−output energy

Answer 1

The correct equation for a machine's efficiency is:

Efficiency = (output energy / input energy) × 100

So the first option is the correct one:

Efficiency = output energy / input energy × 100
