In the picture below, a 7.00 kg piece of aluminum hanging from a spring scale is immersed in water. the total mass of the water is 3.00 kg, and it is contained in a beaker with a mass of 2.00 kg. the beaker sits on top of another scale. find the readings on both scales. take the density of aluminum to be 2700 kg/m3 and the density of water to be 1000 kg/m3.
