A piece of metal with a mass of 3.8 kg and density of 1808 kg/m3 is suspended from a string and then completely immersed in a container of water. The density of water is 1000 kg/m3.
(a) Determine the volume of the piece of metal.
(b) Determine the tension in the string after the metal is immersed in the container of water.
