9) Emad and Jesus are doing remote experiments on planet X, where the absolute pressure at a depth of 2.00 m below the surface of a liquid nitrogen lake is 5.00 * 10' N/m . At a depth 5.00 m below the surface, the absolute pressure is 8.00 * 10' N/m2. The density of liquid nitrogen is BOB ka/m . (10 points) (a) What is the atmospheric pressure on planet X? (b) What is the acceleration due to gravity on planet X
