The answer of how it is convert is the sun generates energy by slowly contracting in size; converting gravitational potential energy into thermal energy and this is called gravitational contraction.  Gravitational collapse is the narrowing of an astronomical object due to the effect of its own gravity, which tends to draw matter inward toward the center of gravity.

12. Which of the following is an example of self-determination?
Papessa [141]

An example of self-determination is the creation of Czechia and Slovakia.

Explanation:

The self-determination basically means that through the will of the people, a certain goal is a achieved usually(not always though) in peaceful manner, in this case ending a country and creating two new ones. Initially it was one country, Czechoslovakia. This country was composed of two main groups of people, the Czechs and Slovaks, and they peacefully collaborated and coexisted as a unit for several decades.

With the fall of the communism though, it became clear that the Czechs and the Slovaks have different ideals, and that they move into different directions. The people voted in a democratic manner to end the existence of Czechoslovakia, and to form to separate countries roughly divided with a border based on ethnic base. The formation of the new countries happened indeed and it was in totally peaceful manner, with the two countries retaining good relations.

Other examples of self-determination are:

  • Creation of Macedonia, Serbia, Croatia, Slovenia, Bosnia out of Yugoslavia
  • Creation of Austria and Hungary out of the Austria-Hungary Empire
  • Creation of the Baltic states out of the Soviet Union
  • Creation of Bulgaria, Greece, Lebanon etc. from the Ottoman Empire
