if there was no atmosphere,the tiny molecules of gases and dust particles will gather together and rain down while the sun shine on the particles making the color glow because the colors are combining into various of colors looking like the galaxy.
The gravitational potential energy of the system will decreases from 1,250 J to 625 J. Option A is corect.
<h3>What is the law of conservation of energy?</h3>
According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
TE=KE+GPE
Case 1;
1450 = 200 J+GPE
GPE=1450 -200
GPE=1250 J
Case 2;
1450 = 825 J+GPE
GPE=1450 -825
GPE=625 J
The gravitational potential energy of the system will decreases from 1,250 J to 625 J.
Hence, option A is corect.

True
Explanation:
Nuclear reactions have many useful applications but they also have harmful biological effects. Nuclear reactions are that occurs in the nucleus of an atoms. They differ from chemical reactions which occurs using valence electrons.
Some uses of nuclear reactions:
- They are used for cancer therapy
- Radioactive tracers.
- Production of energy
- Radiometric dating
Some harmful effects:
- Uncontrolled nuclear reactions can lead to nuclear wastes in the environment.
- They are used in manufacturing nuclear weapons.
- They cause destruction of living cells because they produce ionizing radiations.
