Question

if an input of 100 j in pulley system increases potential energy of load 60 J, what efficency of the system?

Answer 1

Answer:

Efficiency of the system = 100%

Explanation:

Given:

Input energy = 100 J

Potential energy load = 60 J

Find:

Efficiency of the system

Computation:

Efficiency of the system = [Potential energy load/Input energy]100

Efficiency of the system = [60/100]100

Efficiency of the system = 100%
