Answer:

Impossible to determine

Step-by-step explanation:

In other words, no machine can be more than 100% efficient. Machines cannot multiply energy or work input. ... If a machine were 100% efficient then it can't have any energy losses to friction, so no friction can be present. In that case the theoretical and actual mechanical advantages would be equal.

no, simple machine will have an efficiency of 100% if he output work of the machine is equal to the work input.
