Emit greenhouse gases
Explanation:
Nuclear power is regarded as a clean energy source because it doesn't produce or emit greenhouse gases.
Greenhouse gases are mostly generated by the use of fossil fuels that pollutes the environment causing surging global temperature.
Nuclear power is produced by the splitting of radioactive minerals in rods. The process releases a large amount of energy. When the fuel elapses, only radioactive wastes remains.
There is no production of any greenhouse gas in the process of harnessing nuclear energy.
This is why it is considered a clean energy source.

Answer:
The answer is C.
Explanation:
Let's take a glass of water as an example. Now, shine a flashlight on it. See it bend the light into a rainbow? That is a example of refraction. When the light enters the water, the water actually slows down and changes its direction, causing the light to come out the other side in a different way. Since water is very dense, it can bend the water and make it different.
The energy in a photon is given by the formula, E=hf
Where h(plank constant)=6.63×10∧-34Js and
f = frequency of the photon
So the energy of the photon is;
E=(6.63×10∧-34) × (6.0×10∧20)
= 3.978×10∧-13J
From Newton's second law of motion,
F=ma
Where, F = applied force, m = mass (=0.15 kg), a = acceleration.
a= Δv/t, Δv= Change in velocity, t = time
Therefore
a = (41-37)/0.088 = 45.45 m/s^2
Then,
F = 0.15*45.45 = 6.82 N
Answer:
1.it also hleps us to became doctors becuase without physics you can't be a doctor
2.physics needs to be steady whether you like it or not it helps you in life so everybody must study physics no matter is in Uganda USA and plenty more countries there must be physics to dare to be studied
