Answer 2

Answer:

1. The fingers are the agents, lemon is the object. The effect of force is the lemon juice being expelled by squeezing.
2. The agent exerting the force is water. A diving person falls into the water by the gravitational pull. Once inside the water, the gravitational pull is overcame by the buoyancy of the water. This results into an unbalanced force which prevents one from reaching the floor of the swimming pool.
3. When a labourer moving a loaded cart it will move when force applied on it. The force is - Muscular Force. Any interaction that when unopposed will change the motion of an object.
4. It occurs due to Newton first law of Motion. The force is unbalanced and it will stop.
5. His feet exert a muscular force on the ground. This allows him to jump over the bar.
