A student in an undergraduate physics lab is studying Archimedes' principle of bouyancy. The student is given a brass cylinder of mass 1.25 kg. The density of this particular alloy of brass is 8.56 p/cm'. The student ties a massless string to one end of the cylinder, submerges it into a tank of water, and observes a reduction in the apparent weight of the cylinder. @ Macmillan Lea ming With this information, calculate the volume V of the cylinder and the tension T in the string when it is submerged in the tank of water. The density of water is 1.00 g/cm", and the acceleration due to gravity is : = 9.81 m/s . V = cm T= N
