Answer:
A.c
Explanation:
The chromosphere is above the photosphere, the visible "surface" of the Sun. It lies below the solar corona, the Sun's upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density.
In basic terms it is the 2nd one out from the core.
More sales of traditional, large cars are the most likely consequence of falling petroleum prices.
<h3>Explanation</h3>
Since the majority of conventional, large cars employ combustion engines, these engines need petroleum fuel to operate.
As a result, <em>Choice C—more sales of conventional, large cars</em>—is one of the effects of dropping oil prices that is most likely to occur.

The molecular weight of carbon dioxide (CO2) is 44.00 a.m.u., and the molecular weight of propane gas (C3H8) is 44.10 a.m.u. Thus CO2 diffuses_______ C3H8.

Answer:
1. Nuclear fusion does not generate radioactive nuclear wastes as nuclear fission does.
2. Nuclear fusion cannot lead to disastrous powerplant explosions as nuclear fission does.
3. More energy is generated during nuclear fusion than in nuclear fission.
Explanation:
Nuclear fusion involves the combination of lighter atoms such as hydrogen to form a heavier nucleus, in the process producing a tremendous amount of energy.
Nuclear fission on the other hand involves splitting a heavy nucleus into two lighter nuclei, releasing energy in the process.
- Nuclear fusion can be more reliable than nuclear fission in energy generation due to the following reasons:
- There are no radioactive waste products obtained as a result of nuclear fusion, unlike nuclear fission. This is because the elements involved in Nuclear fusion are relatively radioactively stable elements.
- The risk of nuclear powerplant explosion due to out of control chain reactions is reduced in nuclear fusion because the reaction can only occur in perfect conditions under high pressure and temperatures <em>(e.g the sun)</em>. When any of these conditions is removed due to a fault, the reaction automatically stops.
- More energy is generated during nuclear fusion than in nuclear fission.
