Two containers are connected at the bottom via a tube of negligible volume and a valve that is initially closed. Both containers have a cross sectional area of 0.04 m2 The two containers are filled with water (density of 1000 kg/m ) to the same level but while the right container is open at the top, the left one is closed by a piston on which rests a 120 kg. The valve is then opened. When equilibrium is reestablished, determine by what height the right mass m = level goes up with respect to its starting level valve Select the closest answer: O1 m O 2 m O 3 m O 0.5 m O 1.5 m E
