What is impossible for a machine to do?
a) do a greater amount of work than the amount of work done on the machine
b) apply a force in a direction that is different than the direction of the force applied to the machine
c) move an object a greater distance than the distance that part of the machine was moved
d) apply a force that is less than the force that is applied to the machine

A) do a greater amount of work than the amount of work done on the machine

Explanation:

By the principle of conservation of energy, energy can never be created or destroyed.

To do more work by a machine than the amount of work done on the machine is impossible because to do so machine will have to create energy within itself which violates the principle of conservation of energy.

Extra bit,

These kind of machine are defined as perpetual-motion machines and there are many attempts in history to create one such device but all were failed.

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
