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. A star is considered to be in equilibrium when the pressures located in the star balance out the force of gravity. The pressure is thermal pressure that results from the mixture reactions that is happening in the star's core.
