If you dive to a depth of 9.0 m below the surface of a lake, A) what is the pressure due to the water alone? B) What is the absolute pressure at that depth?

(a) Pressure due to water = density * g * h = 1000 * 9.8 * 9 = 88200 Pa

(b) absolute pressure = Pressure due to water + atmospheric pressure
