My name is Emerica and I have taken 2 exams with u and I really like to contact you about other programs that are done in your program. 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.

Carbon burns so rapidly and with so much energy the star blows apart. carbon burning occurs when the helium in the core of the star is gone. when carbon burning occurs, it creates iron. iron is so stable that it ends the nuclear fusion process with the star. Black holes may also cause the death of a star.
