Done moving pulley attached to the object that is being lifted

Answer;

D) one moving pulley attached to the object that is being lifted

Explanation;

-Pulleys are powerful simple machines. They can change the direction of a force, which can make it much easier for us to move something.

-A fixed pulley consists of a wheel fixed to a shaft and is used in conjunction with a belt to transfer energy to another fixed pulley. A movable pulley consists of a shell, a movable wheel and a rope. Movable pulleys are also know as block and tackle.
