(Double points) A machine receives electricity that enables it to deliver a total of 8,542 N of force for the completion of its task. The machine's useful output is 7,023 N. What is the machine's efficiency?

Respuesta :

Answer: machine's efficiency = 82.2%

Explanation:

Efficiency of a machine is the capability of a machine to convert input to output without waste.

It can be expressed as

Efficiency = output/ input × 100%

Output = 7,023N

Imput = 8,542N

Efficiency = 7,023N/8,542N × 100%

Efficiency = 82.2%
