Answer:
0.3950m
Explanation:
Use conservation of angular momentum:
Let L be the angular momentum(a vector).
We know that:
and that the two masses have the same radius:

Hence, the weights are 0.3950m away .
The answer is the first option. The one about doing your best. trust me I read the book today!
Nuclear energy is released during: fission. radioactive decay. man-induced splitting of atoms. Match the basic components of a nuclear reactor with their descriptions. 1. slows down neutrons -> moderator. 2. absorb emitted neutrons -> control rods.
