Anyarometer is a device used to measure the density or a liquid, it is a cylindrical tube weigntea at one ena, 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-5.81 x 102N and a cross-sectional area of A -8.70 x 10³ 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 (o= 1073 kg/m³)? Hydrometer (a) h= Marks for two types of liquids
