Four objects of the same size are in the water tank as shown. Assume all are at rest.Rank the buoyant forces on the objects from highest to lowest.
A metal rod of length 79 cm and mass 1.44 kg has a uniform cross-sectional area of 7.6 cm2. Due to a nonuniform density, the center of mass of the rod is 28.0 cm from the right end of the rod. The rod is suspended in a horizontal position in water by ropes attached to both ends (the figure). (a) What is the tension in the rope closer to the center of mass? (b) What is the tension in the rope farther from the center of mass? (Hint: The buoyancy force on the rod effectively acts at the rod's center.)
A schematic of a homemade hydraulic jack is shown in the figure below, with cylindrical tube ends of different radii, 1 = 0.0480 m and r2 = 0.300 m, respectively.

A hydrometer is a device used to measure the density of a liquid. It is a cylindrical tube weighted at one end, so that it floats with the heavier end downward. The tube is contained inside a large "medicine dropper," into which the liquid is drawn using the squeeze bulb (see the drawing). For use with your car, marks are put on the tube so that the level at which it floats indicates whether the liquid is battery acid (more dense) or antifreeze (less dense). The hydrometer has a weight of W-6.32 x 102 N and a cross-sectional area of A - 9.26 x 10³ m². How far from the bottom of the tube should the mark be put that denotes (a) battery acid (p=1280 kg/m²) and (b) antifreeze (p-1073 kg/m³)?
