Answer:
D
Explanation:
1/2 will be lit with 'daylight' and the other half will be dark
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.
