A U-tube is partially filled with water and then an immiscible liquid is added to the right side.The top of the liquid is a distance h₁ = 2.40 cm above the level of interface between the liquid and water.On the left side of the tube the top of the water is a distance h₂ = 1.48 cm above the liquid-water interface on the right side.What is the density of the liquid in terms of the density of water,1 000 kg/m³? A)1 620 kg/m³ B)617 kg/m³ C)622 kg/m³ D)237 kg/m³

The pressure at the interface must be the same on both sides. Using the hydrostatic pressure formula, ρ_water * g * h2 = ρ_liquid * g * h1. Solving for ρ_liquid gives ρ_liquid = ρ_water * (h2/h1) = 1000 * (1.48/2.40) = 617 kg/m³.
