6. A unit that describes the rate of flow of electricity (current).
8. the spatial period of the wave
12. A ..... is a quantity that has both a magnitude and a direction
15. A physical property of materials which return to their original shape after they are deformed.
16. The transfer of heat by the actual transfer of matter
17. the standard unit of measure for energy and work.
18. An interdisciplinary science using methods of, and theories from, physics to study biological systems
19. a change in momentum

1. A basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons
2. a combination of two or more cells (electric), which produces electricity
