Is there a balance between pressure and gravity in main sequence stars?

Gravity is constantly pulling the matter of a star together, while the nuclear fission reaction that makes the star shine and put off heat is trying to make it explode. The two are very precariously balanced.

What two things balance to maintain of a star?
Pressure and gravity
Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
what best decribes stellar equilibrium apex?
The balance between pressure caused by heat and gravity caused by the star's mass.
How does hubble stay in orbit?
Any satellite is in a careful balance between gravity and inertia.
What does the equilibruim between the outward pressures of radiaion and the force of gravity do?
While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star.
What can upset the balance between gravity and pressure in a nebular?
You used the term nebular. I take it you mean a galaxy. There would not be a balance between gravity and pressure. There would be a balance between gravity and centrifugal force.
What two events can upset the balance between gravity and pressure a nebula?
The balance between gravity and pressure can be upset if two nebulas collide. It can also be upset if a nearby star explodes.

What two events can upset the balance between gravity and pressure in a nebula?
Two events that can upset the balance between gravity and pressure in a nebula are a supernova explosion or the collision of two nebulae. A supernova explosion releases an enormous amount of energy and can disrupt the delicate equilibrium between gravity and pressure. The collision of two nebulae can also disturb the balance by introducing additional gravitational forces and increasing the overall pressure within the system.
What to things balance to maintain the shape of the star?
Pressure and gravity
What two things balance to maintain of a star?
Pressure and gravity
When a star's inward gravity and outward pressure are balance the star is said to be?
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.

Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
What is the relationship between pressure and gravity on a red giant?
To start with, the star's gravitational attraction is not sufficient to offset the outward radiation pressure. As a result, the star increases in size until the two are in balance.
How long will your sun remain a main sequence star?
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity, with that the core contracts and temperature rises. This cause outer layers to cool and expand. In this late stage of the star's life cycle, it is called a giant. The sun will continue to be a main sequence for about 5 billion years, then the sun will become a giant.
