Question

What is hydrostatic equilibrium in a star? a) The balance between radiation from the surface and the rotation rate b) The expansion of the core when it is heated c) The increase in the rate of fusion when the star runs out of hydrogen d) The balance between the force of gravity directed in and thermal pressure directed.

Answer 1

Answer: d) The balance between the force of gravity directed in and thermal pressure directed

Explanation:

Hydrostatic Equilibrium helps to put in perspective star as self- regulating systems . It makes it plain that the energy generated in the star's hot core, is carried outward towards the cooler surface.
