The combination of decay processes that would convert U-239 into PU- 239 is beta decay followed by another beta decay. Beta decay involves the emission of an electron [positron]. There are two types of beta decay; positive and negative beta decays and both occur simultaneously in order to move the atoms towards stability.

Which statement best describes a mechanical wave?
Minchanka [31]

Answer:

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.

Explanation:

While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
