Answer:
I haven't studied this, I think, so this is off of what I think it might be, I suppose.
Explanation:
A: If it's widespread, it might be harder to govern everyone rather than if it was more compact. If it's bigger, one center of power in one part might not be able to handle monitoring the entire country as there's al lot of space, so their influence might not be felt throughout the entire country and rather more in the areas closest to it. Like how people who lived in England were seemingly more loyal to the king, but in America, which was an ocean away, more people seemingly felt and expressed their lack of connection to a ruler so far away.
B: If it's wide-spread enough, there might be different ideas of grouping based on it. If a river runs through it, for example, it could lead to a "east of the river" versus "west of the river" difference in how they identify. An example of this is in Italy where the North and South have differences between them or how in the U.S. there had been/is the idea of "The North vs. The South" or even "The North vs. The South vs. The Midwest vs. The West Coast".
Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
