I want to know if you have institute or college that offers nursing programs, if so, what's the requirements.
As the gas falls together, it gets hot. A star forms when it is hot enough for nuclear reactions to start. This releases energy, and keeps the star hot. Gravity pulls the dust and gas together. During its 'main sequence' period of its life cycle, a star is stable because the forces [force: A push or a pull.The unit of force is the newton, 'N'. ] in it are balanced.The outward pressure from the expanding hot gases is balanced by the force of the starâs gravity. Our Sun is at this stable phase in its life.uring its 'main sequence' period of its life cycle, a star is stable because the forces [force: A push or a pull.

Hi. The life span is dependent solely on the mass of the star. The more mass the shorter the life span. A normal star like the sun has about a 10 billion year life span. A smaller star will burn (fuse) more slowly while a more massive star will burn (fuse) much more rapidly.ll the first 4 answers are correct. Unlike a bonfire, and contrary to intuition, the bigger a star, the shorter the life. In the case of a red dwarf, the star may glow for as long as 10^14 years.
