A)volumes.
B)densities.
C)weights.
D)number of molecules.
E)none of the above

Question

Quizplus · Accepted Answer

The pressure at the bottom of a fluid column depends on the height of the fluid, the density of the fluid, and the acceleration due to gravity. Since the pressures are equal and the tubes have equal cross-sectional areas, the weights of the water and mercury columns must be equal. This is because pressure is equal to the weight of the fluid divided by the area over which it acts.
