Unstable nuclei split up in a process<span> called </span>radioactive decay<span> and emit </span>radioactive radiation<span>. You need to know the effect of alpha and </span>beta decay<span> on the nucleus. The nucleus of an atom can be represented as: ... A = </span>atomic<span> mass (number of protons + neutrons)

Answer:
Explanation:
Mechanical energy = Gravitational potential energy + kinetic energy
Time Gravitational potential energy kinetic energy Total ME
0 4 0 4
2 2 2 4
4 0 4 4
6 2 2 4
8 4 0 4
and so on .....
We see that total mechanical energy is always 4 which is constant .
So gravitational and kinetic energy changes cyclically but total mechanical energy is constant .
