Define efficiency. The efficiency of a simple machine is 75%. What does it mean?

Efficiency is how thorough it is or how much the producing strength is or how ongoing it can be without having to stop. It might not be the best answer but hey I am only in 8th grade.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
