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.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
