Acarpenter uses a crowbar to remove the top of a box. the top has a resistance of 500 n. the carpenter applies an input force of 250 n. what is the mechanical advantage of the crowbar?

use the formula mechanical advantage = output force/input force to solve the following problem.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

Iwould sure like to answer your question but i honestly just don’t know
