a) here , your fingers are the agent exerting force
effect of force -- muscular force
b)the agent exerting force is water
effect of force-- actually gravitational force but we can say it's buoyancy( the ability of a body to float )
c) the loader is exerting the force
effect of force -- muscular force
d) engine and friction between the wheels and the road is the agent exerting the force
effect of force -- frictional force
e) In the high jump by the athlete the force acts on the ground and the ground helps the athlete in jumping. The effect is change in motion and the cause is muscular force or friction force.
hope this helps you .. all the best!!!
