42. Go A hydrometer is a device used to mea- sure 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 Hydrometer 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 in- dicates whether the liquîd is battery acid (more dense) or antifreeze (less dense). The hydrometer has a weight of Ww = 5.88 × 10-² N and a cross- sectional area of A = 7.85 × 10-³ m². How far from the bottom of the tube should the mark be put that denotes (a) battery acid (p = 1280 kg/m³) and (b) antifreeze (p = 1073 kg/m')? Marks for two types of liquids.
