Answer:

Because it gives a direct relation that can be used to obtain the efficiency E = Input/output which tell us how the system works, for example, if the efficiency is bigger than one, this means that the system amplifies the input (the output is bigger than the input) while if the efficiency is less than one, the output is smaller than the input.

Where these quantities can be forces, heat, electricity, or anything.

Melissa's favorite exercise equipment at the gym consists of various springs. in one exercise, she pulls a handle grip attached

konstantin123 [22]

The formula for force exerted on/by a spring is

F = k*e where k is the spring constant and x is the distance stretched from unstrained position. This should allow you to find what you need.

Using F = k x e,

where k is the spring constant,

and e is the extension,

The F is her weight = 45 X 0.80

= 36 N
