Explanation:
In a nuclear reactor, the superheated water leaving turns to steam when released and it in turn is channeled to turn turbines in order to produce electricity.
A nuclear reaction is used to generate current through a series of processes. The reaction produces a significant amount of heat energy. This heat energy is used to superheat water and convert it to steam. The steam is then channeled to drive turbines whose mechanical rotation produces electricity.Answer:

Evaluate the extent to which religious belief shaped societies before 1200 CE
Answer:
Before 1200 CE, religious belief had a huge impact on societies and how they functioned.
Explanation:
Religious belief has most probably occurred as early as the appearance of modern-day humans. Throughout human history, it has had a huge influence on societies and how they function. This was simply due to the fact that humans had very limited knowledge so religion was used to explain things, as well as to justify certain actions.
t Religion had such a stronghold until 1200 CE, and since then its influence has been gradually declining. Religion had such a big influence on societies that very often the religious authorities were even more powerful than the political figures, or they were the same. The influence was not just seen in public, but also in the private lives of the people, and unfortunately, often it has been abused to have full control of the people and their actions and punish or even kill the ones that dared to do things differently.

Urban Sprawl increases carbon dioxide emissions by
1 - expanding the use of public transportation
2 - increasing the need to drive
3 - generating more factories
Urban Sprawl increases carbon dioxide emissions primarily through increasing the need to drive. Therefore, option (2) is correct.
Urban sprawl occurs when cities expand into suburban or rural areas, resulting in low-density development, longer commutes, and more car use. Vehicle use raises [tex]CO_{2}[/tex] emissions.
As cities expand, distances between homes, businesses, and other destinations grow, making public transit less efficient. This increases private vehicle use for commuting and transportation. Private automobiles emit carbon dioxide by using fossil fuels like petrol.

A country is experiencing neagtive population growth which of the following would help stabilize their population in the long term?
A. Decrease the death rate
B. Increase the birthrate
C. Decrease the birthrate
D. Maintain both birth and death rate at their current levels
Answer:
A.
Explanation:
Decreasing the death rate of a nation carries with it a healthier population, as people are not dying as quickly whether that be due to greater education, more food, better sanitation or otherwise. A higher birthrate would likely only amount to more restrictions for a nation that it evidently cannot sustain due to its declining population. Essentially; improve the quality of life, not the quantity of it, the more people live, the more children they will eventually have instead of fighting for their lives to survive.
