Toy remote control cars require batteries as a power source. identify the energy transformation that powers an electric generator in a toy remote control car. a) it transforms electrical energy into kinetic energy. b) it transforms kinetic energy into electrical energy and then into chemical potential energy. c) it transforms chemical potential energy into kinetic energy and then into electrical energy. d) it transforms chemical potential energy into electrical energy and then into kinetic energy.

D) It transforms chemical potential energy into electrical energy and then into kinetic energy.

Explanation:

A battery is a device that consists of electrochemical cells. These batteries transform chemical potential energy into electrical energy. The cells have external connections that allow us to charge the items that use them. In this case, the toy remote control car. The car is able to run because of the transformation of this energy into kinetic energy (energy for movement).

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
