For the majority of the life of a star, the gravitational force (due to the mass of the star) and the gas pressure (due to energy generation in the core of the star) balance, and the star is said to be in ‘ hydrostatic equilibrium ’. This balance is finely-tuned and self-regulating: if the rate of energy generation ...

Stellar equilibrium is a balance between the outward pressure produced by the energy generated in a star's core and the inward force of gravity acting on the mass of the star. In a stable star, these two opposing forces are balanced, preventing the star from collapsing under its own gravity or exploding due to excessive pressure.A stellar equilibrium is a state of balance in which a star’s internal pressure is equal to the weight of the star’s material and the star’s luminosity is equal to the rate at which energy is being generated by nuclear reactions in the star’s core.

Explanation:Short-run equilibrium. An economy is in short-run equilibrium when the aggregate amount of output demanded is equal to the aggregate amount of output supplied. In the AD-AS model, you can find the short-run equilibrium by finding the point where AD intersects SRAS. The equilibrium consists of the equilibrium price level and the equilibrium output.The equilibrium concentration of \(O_2\) is a constant and does not depend on the amount of \(HgO\) present. Hence adding more \(HgO\) will not affect the equilibrium concentration of \(O_2\), so no compensatory change is necessary. \(NH_4HS\) does not appear in the equilibrium constant expression because it is a solid.Which best describes stellar equilibrium?
