A simple hydrometer is made using a flat base test tube of mass 15g and length 12cm. The test tube is partly filled with lead shots. Given that the test tube has a uniform cross section are of 2.0cm² and 10cm of its length is under water. Calculate
i) The mass of the lead shots in the test tube.
ii) The length of the test tube immersed if placed in brine which has a density of 1.25g/cm³
iii) The lowest density of liquid in which this test tube would float.
