Apulley requires you to pull 3 times the amount of rope in order to lift an object. therefore, the mechanical advantage is

a. 1/3
b. 1
c. 3
d. 30

1

Explanation:A pulley is an example of a simple machine that is made up of ropes and wheels.Mechanical advantage refers to the number of times that a simple machine multiplies the input force. This means if a simple machine has a mechanical advantage of 5 then it means that it made the work done 5 times easier than without it.It also means that one would apply 1/5 times the force they would have applied without the machine.In this case, the pulley which is a simple machine requires you pull 3 times the amount of the rope. Therefore, the mechanical advantage of the machine is 1, which means the output force is equal to the input force.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
