Q1. The drawing shows a side view of the swimming pool. The pressure at the surface of the water is atmospheric pressure. The pressure at the bottom of the pool is greater due to the weight of water above it. As a storm approaches, atmospheric pressure drops. What happens to the pressure at the bottom of the pool?

Q2. A thin, light wire is wrapped around the rim of a wheel. The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.28. An object of mass 4.0 is suspended from the free end of the wire. The system is released from rest and suspended object descends with constant acceleration.
