In a real system of levers, wheels, or pulleys, the AMA is less than the IMA because . the resistance force is greater than the effort force
the work input is dependent on the work output
some of the effort force must do work against friction
the effort force is greater than the resistance force

the work input is depented on the work output

Explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
