What does the equilibrium between the outward pressures of radiation 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 does the euilibrium between the outward pressures of radiation and the force of gravity do?
It allows the sun to be relatively stable for the last 4.5 billion years. (and hopefully for the next 5 billion.)
What is the relationship between center of gravity and support base for an object in stable equilibrium?

What is the relationship between the intensity of the radiation given off from a radiation source and distance from the radiation source?
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
If an object if in unstable equilibrium any displacement will?
If an object is in a state of unstable equilibrium, any displacement will lower that objects center of gravity.
Which is not a form of electromagnetic radiation?

Gravitational equilibrium means that the surface and the core of the Sun are at the same pressure?
The Gravitational Equilibrium of a star is when the amount of gravity being exerted by the center of the star on the outer particles of the same are balanced by a force pushing the particles out. In other words, it is when a star is not shrinking or condensing because of its own gravity. Possible outward forces counteracting the gravity could be radiation, heat, shockwaves, seismic waves, etc.
What is the antonym for radiation?

Does gravity cause rockflow?
Yes, but so does internal pressures. (Which wouldn't exist if gravity wasn't present.)
What is rest position or equilibrium position?
Rest position or equilibrium position occurs when all the forces (gravity, the wind, friction etc) exerted on an object are equal.For example, a rolling ball is not in equilibrium because one or more forces (gravity or the force you used to initially move the ball) are greater in strength than the friction (both between the ball and the surface it is rolling on and between the ball and the air).The ball will stop rolling when the force causing it to move 'forwards' is overcome by frictional force. The ball will then be in equilibrium, or at rest.
Stellar equilibrium relies on fusion and gravity to maintain stars in their current form?
Yes, a stable star is in equilibrium, called hydrostatic equilibrium, when the outward pressure from heat caused by core fusion processes balances the inward pull of gravity. There are other factors which alter the form of stars such as their rotation or gravity from external sources such as a nearby mass.
If an object if in unstable equilibrium any displacement will?
If an object is in a state of unstable equilibrium, any displacement will lower that objects center of gravity.

A ball thrown straight up has zero velocity at its highest point Is the ball in equilibrium at this point?
Yes, a ball is in equilibrium at the top of it's throw because there is a moment of no change, or equilibrium, when it is suspended in air.
