Which are associated with nuclear fission but are not associated with nuclear fusion? check all that apply. neutrons striking nuclei two small nuclei joining together the release of large amounts of energy a single large nucleus breaking apart two small nuclei forming

neutrons striking nuclei

a single large nucleus breaking apart

two small nuclei forming

Explanation:

- Nuclear fission occurs when a large, unstable nucleus absorbs a slow-moving neutron and breaks apart into two smaller nuclei + additional neutrons. In the process, the mass of the final product is smaller than the mass of the initial nucleus, so this mass difference is converted into a large amount of energy, according to Einstein's equation:

- Nuclear fusion occurs when two small nuclei join together forming a larger nucleus. In the process, the mass of the final nucleus is smaller than the sum of the masses of the initial nucleu, so this mass difference is converted into a large amount of energy, according to Einstein's equation:

We can now analyze each statement and see which one is valid only for nuclear fission:

neutrons striking nuclei --> valid only for nuclear fission

two small nuclei joining together --> valid only for nuclear fusion

the release of large amounts of energy --> valid for both fission and fusion

a single large nucleus breaking apart --> valid only for nuclear fission

two small nuclei forming --> valid only for nuclear fission

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

the ima (higher than 1m) will be greater than the ima with the height of 1m.
