1. In a hydraulic lift, if you exert a downward force of 100 N on a piston with an area of 1 m^3, how much upward force would be exerted on a piston with an area of 20 m^3?

2. What would be the absolute pressure at a depth of 2 m in a swimming pool? (Density of water is 1000 kg/m^3, density of air is 1 kg/m^3, use 10.0 m/s^2 for acceleration of gravity)
