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.

  The diagram below shows a wooden block of dimensions 50cm by 40cm by 20cm held in a position by a string attached to the bottom of a swimming pool.
  
  i) The three forces acting on the block are the tension (T) in the string, the weight (W) of the block and the upthrust (U) due to water.
  Write an equation relating T, W and U when the block is at stationary.
  ii) What is the weight of the block.
  iii) What is the weight of the water displaced by the block.
  iv) Determine the tension (T) on the string. (density of the block is 600kgm^-3; density of water is 1000kgm^-3)
