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.

inertia is the answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The answer should be D but if its not then im sorrry, idk
Answer:
0m
Explanation:
since the string is rigidly attached to the post, the reflected and incident pulses are of the same amplitude but different polarities. At the point where the two pulses meet, the amplitude will be the addition of that of the incident and the reflected pulses. i.e Amplitude= 0.25 + -0.25=0m
Gravitational potential energy above a reference level is M G H .
In this story,
-- M = 25kg
-- H = 15m
and if the story takes place on Earth, then
-- G = about 9.8m/s².
PE = (M) (G) (H) = (25) (15) (9.8) = <em>3,675 joules</em> .
That's the gravitational potential energy acquired by the suitcase
in the process of being lifted 15 meters straight up.
Sadly, human physical effort is far from 100% efficient, and the woman in
the story has to expend a lot more energy than that just to lift the suitcase
up the stairs. AND PLUS don't forget that she also has to come up with
enough additional energy to increase the potential energy of <em>her own</em> mass,
no matter how dainty it may be, by 15 vertical meters' worth.
Now 25 kg = about 55 pounds,
and 15 meters = about 50 feet, or something like 4 to 5 stories
You can be sure that some beads of glow highlight her forehead
by the time she's done with this job.
