Pressure Practice Test

A sealed container holds water at rest. Point A is $0.20,\text{m}$ below the surface; point B is $0.50,\text{m}$ below the surface. Pressure is due to fluid depth. Which point has greater water pressure?

A $400,\text{N}$ crate rests on the floor on four identical square feet. Each foot has area $1.0\times10^{-3},\text{m}^2$. Pressure is due to contact force. What is the pressure on the floor under one foot?
