Describe how energy changes from a usable form to a less usable form in a building's heating system.

What forms of energy are provided by the sun?

Episodic memory is the memory system that holds what kind of information?

The energy you use to walk from point A to point B is a result of several energy transformations from one form to another beginning with energy from the sun. The net result of these transformations is a. a loss of energy. b. fewer electrons. c. an increase in heat energy. d. an increase in usable energy. e. a decrease in entropy.

For each question, select the best answer from the four alternatives. Which part of an electric circuit transforms electrical energy into other usable forms of energy? (a) load, (b) switch, (c) power source, (d) connecting wire.
