On which factor mechanical advantage of simple machine depend on? Please help me and perfect answer will be brainlest answer.

The factor that determines the mechanical advantage (or ideal mechanical advantage (IMA) - in the absence of frictional forces) in a simple machine is the ratio perpendicular distance of the applied force to the fulcrum to the perpendicular distance of the load to the fulcrum

The mechanical advantage can therefore by larger than 1 (requiring less force per load), or equal to 1 (effort equal to load) or less than 1( effort more than load)

Explanation:

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

radiation

explanation:

heat is transmitted by radiation
