How does radiation differ from conduction? a) radiation can move through empty space to transfer heat; conduction cannot. b) radiation needs a medium in order for heat to transfer; conduction does not. c) radiation requires objects to have direct physical contact; conduction does not. d) radiation transmits heat by circulating particles in an object; conduction does not.

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
