A simple U-tube contains a liquid of density ρ1. A second liquid of density ρ2 (ρ2 < ρ1) is poured into the right arm until it reaches height h above the right surface of the first liquid. (a) How high does the first liquid rise in the left arm from its initial level? (b) If the ratio of the densities is 15, and h = 25 cm, Compute the change in the height of the first liquid in the left arm of the U-tube.
