Agent Exerting Force:
The agent exerting force in this scenario is the person who is diving into the swimming pool.

Effect of Force:
The force exerted by the person diving into the swimming pool has several effects:

1. Momentum: As the person jumps into the pool, they apply a force against the water, creating a momentum. Momentum is the product of an object's mass and its velocity. The greater the force exerted, the greater the momentum gained by the person.

2. Displacement: The force applied by the person diving into the pool causes a displacement of the water. The water is pushed aside as the person enters the pool, creating a wave or splash.

3. Buoyancy: When the person enters the water, they experience a buoyant force acting against their body. This force is exerted by the water and opposes the force of gravity. It allows the person to float or stay afloat in the water.

4. Water Resistance: The force exerted by the person diving into the swimming pool also encounters resistance from the water. This resistance is known as drag or water resistance. It depends on factors such as the person's body shape, speed, and the viscosity of the water. The person needs to overcome this resistance to enter the water smoothly.

5. Splashing: As the person's body enters the water, the force causes a displacement of the water molecules. This displacement creates a splash or wave that can be observed on the surface of the pool. The size and intensity of the splash depend on the force exerted by the person and the angle at which they enter the water.

6. Sound: The force exerted by the person diving into the water also creates a sound. When the person's body hits the water surface, it generates vibrations that travel through the water, producing a sound that can be heard.

Overall, the force exerted by the person diving into the swimming pool has various effects, including the creation of momentum, displacement of water, buoyancy, water resistance, splashing, and sound. These effects are a result of the interaction between the person's body and the water.
