D)

It has played a role throughout the Sun's history, but it was most important right after nuclear fusion began in the Sun's core. What do we mean when we say that the Sun is in gravitational equilibrium? ... There is a balance within the Sun between the outward push of pressure and the inward pull of gravity.

When we say that the sun is in gravitational equilibrium, it simply means that there's a balance within the sun between the outward push of pressure and the inward pull of gravity.

  • The sun is important as it holds the solar system together. The sun is the most important body to the Earth. It. helps in the provision of heat and energy to the Earth. Without the sun, the Earth will be lifeless.

  • It should be noted that the sun is stable. In this case, it's neither contracting nor expanding. In this case, the sun is in equilibrium and the forces within it are balanced.

  • Gravitational Equilibrium ensures that the core of the sun is at the right level of nuclear fusion.

  • When the sun is in gravitational equilibrium, there is a balance within the sun between the outward push of pressure and the inward pull of gravity.

In conclusion, the amount of energy that's released by fusion in the core of the sun will then be equal to the amount of energy that radiated from the surface of the sun into space.
