The stable number of sunspots that exist on a star's surface 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.Which best describes a stellar equilibrium? Stellar equilibrium is also known by its other term hydrostatic equilibrium. A star is considered to be in equilibrium when the pressures located in the star balance out the force of gravity. A star will remain in equilibrium until such time when the supply of hydrogen in the core is exhausted.

The mass of a star determines exactly where it falls on the main sequence. As Figure 21.12 shows, massive stars on the main sequence have high temperatures and high luminosities. Low-mass stars have low temperatures and low luminosities. Objects of extremely low mass never achieve high-enough central temperatures to ignite nuclear reactions.

Mass inside a given radius in the Sun Density profile in the Sun Pressure profile in the Sun The simplest commonly used model of stellar structure is the spherically symmetric quasi-static model, which assumes that a star is in a steady state and that it is spherically symmetric.What best describes stellar equilibrium? The balance between pressure caused by heat and gravity caused by the star's mass. What do you call The balance of forces that keeps a star from collapsing?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.Study with Quizlet and memorize flashcards containing terms like Which statement best describes why a government's actions are important in macroeconomics?

To “solve” a stellar structure means to theoretically calculate its physical quantities (temperature, pressure, density, luminosity production etc..) at each point inside the star. To do this one has to solve the so called “stellar equilibrium equations” which reflect the stellar characteristics describing its working principles. 3.1.Equilibria Dynamic equilibrium. Reversible reactions in closed systems reach equilibrium where the rates of forward and reverse reactions are constant. Pressure,...of hydrostatic equilibrium. While the star is burning hydrogen in its core, the temperature is highest at the center. For an ideal gas, this temperature gradient helps support the star, while for an isothermal core, the density gradient alone must support the stellar mass, and the density gradient steepens.8.2.

The Hardy-Weinberg Equilibrium (HWE) is an important fundamental principal of population genetics, which states that “genotype frequencies in a population remain constant between generations in the absence of disturbance by outside factors” (Edwards, 2008).According to HWE, for a locus with two alleles A and a with …Dec 30, 2020 · Local Thermodynamic Equilibrium. Consider the motion of an individual atom in the stellar photosphere. We know that the temperature must gradually decrease from the center outwards towards the edge. If the mean free path (mfp) of the atom typically takes it from a region of one temperature to a region with a different temperature, static equilibrium (3). Hydrostatic equilibrium implies a local balance between pressure and gravity, can be expressed as: dP dr Gmρ r2 (1) where P is the pressure, ρis the density, and m is the mass contained inside the radius r.
