Pressure in a fluid: At a certain depth in the ocean, the absolute pressure is p. If you go to twice that depth (treating the water as incompressible)
A) the absolute pressure will be 2p.
B) the absolute pressure will be less than 2p.
C) the absolute pressure will be greater than 2p.
D) the gauge pressure will not change.
E) the gauge pressure will increase but will not double.

Question

Quizplus · Accepted Answer

The absolute pressure at a depth in a fluid is given by the sum of atmospheric pressure and the pressure due to the fluid column above. At twice the depth, the pressure due to the fluid column doubles, but the atmospheric pressure remains constant, so the absolute pressure is less than 2p.
