How does a star form?

Answer 1

There are huge clouds of gas and dust in space.Due to some shock waves the gas get accumulated in one point and its mass increases.

This will cause more mass to be attracted due to gravity. after a long period the pressure and temperature at the core will be very high..When the temperature reaches about 15 million atn the core nuclear fusion will start and star began to shine..In the core 4 hydrogen atoms will fuse togather and form 1 helium atom and about 0.7% mass will be converted into energy.

A star is created when a cloud of gas and dust known as a nebula is drawn together by gravity, which causes the material to condense and heat up. Nuclear fusion then starts in the core of the star when it reaches a high enough temperature and pressure, producing energy and allowing the star to shine.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
