2. renewable organic matter
5. a wave where the oscillations or vibrations of the medium are parallel to the direction the wave is traveling
6. a wave where the oscillations of the medium are perpendicular to the direction of the wave's propagation
9. the rate at which a periodic event or oscillating wave repeats
14. high point of the wave
15. closed path that electric curent flows
16. flamible liquid formed from the decay from aincint orginisims

25. form from the remains of ancient plants and animal that where daried
26. low point of the wave

1. energy release when the nucleus splits apart
3. when atom nuclei combine at very high tempitures
4. the rate at which electrical energy is converted to another form of energy
7. disturbance or variation that transfers energy
8. the bending of waves as they pass around an obstacle or through an opening
10. a material through which electrons move easily
11. the spatial period of a wave
12. the change in direction (bending) of a wave as it passes from one medium to another
13. material or substance through which a wave propagates or transfers energy
17. law current in a circuit equals the voltage difference divided by the resistance
