Constants 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 m/s. The pressure at the surface of the water will be 145 kPa , and the depth of the water will be 13.8 m. The pressure of the air outside the tank, which is elevated above the ground, will be 86.0 kPa Part A Find the net downward force on the tank's flat bottom, of area 1.55 m2 , exerted by the water and air inside the tank and the air outside the tank. Assume that the density of water is 1.00 g/cm³. Express your answer in newtons. • View Available Hint(s) Πνα ΑΣφ N

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
