Question

Constants Part A You are assigned the design of a cylindrical pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 meters per second per second. The pressure at the surface of the water will be 105 kPa, and the depth of the water will be 14.1 m. The pressure of the air in the building outside the tank will be 89.0 kPa Find the net downward force on the tank's flat bottom, of area 2.10 m, exerted by the water and air inside the tank and the air outside the tank. Express your answer numerically in Newtons, to three significant figures. View Available Hint(s) 2.48 10 Submit X Incorrect: Try Again; 5 attempts remaining

Explanation / Answer

Solution:

a) Net force = P * A + p * g * h * A - Pout * A

=> F = (105 * 10^3 + 1000 * 3.71 * 14.1 - 89 * 10^3)* 2.10

=> F = 1.43 * 10^5 N is the right answer
