Given Mass = 400g and V = 20cm3 Density = Given Mass = 725g and V = 25cm3 Density =.
Given Mass = 131.4g and V = 18ml Density =
Given Mass = 67.7g and V = 9ml Density =

Can somebody please help me find the density.

Exothermic,  physical change after it is already baked

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
