a u-tube contains mercury with a density of 13,600 kg/m^3. it is open on one end, and the other end is connected to a boiler, which contains water at high pressure. the water from the boiler pushes directly on the mercury column. what is the gauge pressure at point A in the boiler? (pt a is located at the point where the boiler connects to the arm of the u tube)
