Nuclear fusion is a thermonuclear reaction in which light stable nuclei combine with each other in order to form a heavy stable nucleus with the release of large amount of energy.
In case of stars, four hydrogen nuclei combine with each other to form a helium nucleus with a release of 26 Mev per cycle.
Thus, nuclear fusion occurs in stars is true statement.
Car with a mass of 1210 kg moving at a velocity of 51 m/s. 2. What velocity must a 1340 kg car have in order to have the same momentum as a 2680 kg truck traveling at a velocity of 15 m/s to the west? 3.0 X 10^1 m/s to the west.
