Answer is 1.0

1.0 The mechanical advantage makes the work output greater than the work input. True, because

2.0 The machine can put out force without having any force applied to it.

False. Law of conservation of mass and energy states that force can neither be created nor destroyed. Without the input force no force will be translated to output force.

3.0 A large force can be exerted through a long distance to have a small force exerted through a short distance. False - The idea of using machine is to multiply the input to the output force

4.0 A large force can be exerted through a short distance to have a small force exerted through a long distance. False - The idea of using machine is to multiply the input to the output force
