Chapter 26.1, Problem 3bTH
A U-tube is partly filled with water. Oil is then poured on top of the water on one side. The final water levels on both sides shown. The surface of the oil is not shown.
Points A and D are at the same level; points B and C are at the same level.
b. Will the pressure at the top surface of the oil be greater than, less than, or equal to the pressure at point D (Hint: What is the pressure at point D?)

- Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight).
