What do you call The balance of forces that keeps a star from collapsing?
Dynamic equilibrium.
For the sun to be stable the inward and outward forces within the sun must be?
In equilibrium.
What major forces and or pressures drive stellar evolution?
The fact that each star starts out with all the hydrogen that its ever going to have.
Why doesn't the sun blow up like a hydrogen bomb?
There is a temperature-pressure equilibrium that needs to be maintained. As more reactions take place the heat forces the interior of the sun to expand against the force of gravity, which is what keeps the explosion from moving outward. However, as the interior expands, the temperature cools until it is no longer hot enough for subsequent reactions to occur, leading to a collapse (because the gravity has not changed). As it begins to collapse, pressure and temperature increase, leading to increased reactions. This repeats as an equilibrium. A hydrogen bomb does not have a secondary constraint on the explosion like uniform pressure from gravity, which allows it to consume all of its resources on an initial expansion.
When does a forming star become stable?
Usually, gravitational collapse of the protostar is stopped after hydrogen fusion starts in the center. Then gravitational forces and radiation pressure are in equilibrium.
What are the conditions of equilibrium when a number of parallel forces are acting on a body can a moving body be in equilibrium explain?
The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium. But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.
How to make a system of forces in equilibrium just by changing the angles of forces?
By the changing the angles of forces, the system of the forces will be in equilibrium.
Can an object be moveing and still be in equilibrium?
Yes. If the sum of the forces is zero, then the object will not accelerate - meaning it will maintain its speed.
What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium
What is the importance of equilibrium in the study of chemical reactions?
Equilibrium denotes a condition where the sum of forces is zero or balanced. This condition is related to Boundary conditions or limit values for Energy.This is important because at Equilibrium the forces are balanced and the condition is said to be stable and unchanging.
What are the forces in equilibrium?
action and reaction
When forces are balanced what do they call?
equilibrium
Where does equilibrium come from?
Equilibrium is a state of balance. In physics and chemistry, it occurs as a dynamic state where opposing forces or reactions result in a state whose average is at least roughly the same.In the human body, the state of equilibrium (balance) is provided by the inner ear and the visual center of the cerebellum.The word equilibrium is from the Latin equi(aequi) meaning equal, and libra, meaning balance.
What is the condition of coplanar forces in equilibrium?
In equilibrium, the sum of total vertical, total horizontal forces = 0, and movement of the body = 0.
What are equilibrium of coplanar forces?
equilbrium in coplaner forces at rigid body.
First condition of equilibrium?
In First condition of equilibrium the sum of all forces is zero.
What is another word for balanced forces?
Equilibrium.
