Look it up it's really easy :) I don't really remember all of this. I haven't learned about this stuff since like 7th grade
Answer:
B. neutrons
Explanation:
When a free neutron hits the nucleus of a fissile atom like uranium-235 (235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons. Fission can be self-sustaining because it produces more neutrons with the speed required to cause new fissions. This creates the chain reaction.
Ozone is your answer, it has three oxygen molecules instead of two.
Answer:
11.47 m high
Explanation:
All of the Kinetic Energy converts to Potential energy
1/2 m v^2 = mgh divide both sides by 'm'
1/2 v^2 = gh (note that the masses given are irrelevant !)
(1/2 v^2) / g = h
(1/2 (15^2) / 9.81 = h = 11.47 m
