Question

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

Efficiency=output energy/input energy . 100

efficiency is equal to output energy over input energy multiply 100

Efficiency=input energy+output energy

cap efficiency is equal to input energy plus output energy

Efficiency=input energy−output energy

cap efficiency is equal to input energy minus output energy

Efficiency=input energy/output energy ⋅ 100

efficiency is equals to input energy over output energy into 100

Answer 1

Efficiency = (output energy / input energy) × 100

Explanation: Efficiency is the fraction of input energy converted to useful output energy, usually expressed as a percent.
