The temperature of water at the bottom of a large waterfall is higher than that of the water at the top. because (1) the falling water absorbs heat from the Sun. (2) the water at the bottom has greater potential energy. (3) the kinetic energy of the falling water is converted into heat. (4) rocks on the bed of the river give out heat.

Why in electric motor or generator heating due to current involves dissipation of electrical energy?
Why in electric motor or generator heating due to current involves dissipation of electrical energy?
Last answer:
In electric motor or generator heating due to current involves dissipation of electrical energy because as the current increases there will be I2R losses. More current flow means more the heat will be generated and as the temperature of conductor increase its resistance increases.
