Which best describes stellar equilibrium.
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.

The stellar equilibrium is the state in which the gravitational force exerted by the mass of the star is balanced by the pressure gradient force within the star. In a fusion reaction, the outward pressure of the hydrogen gas keeps the star in equilibrium. A collapse of the star would be unavoidable if the pressure became too great.When a 0.62 kg mass on a vertically hung spring is displaced 0.21 m from equilibrium, the spring constant is approximately 28.93 N/m. First, let's calculate the force exerted by the mass when the spring is displaced. The weight of the mass can be determined using the equation F = m * g, where m is the mass and g is the acceleration due to gravity.Stellar equilibrium is also known by its other term hydrostatic equilibrium.
