Which two forces balance each other out in a star?*1 pointStrong nuclearWeak nuclearGravitationalElectromagneticThermal Pressure

The two forces that balance each other out in a star are the gravitational force and the thermal pressure.

Here's a step-by-step explanation:

1. Gravitational Force: This is the force that pulls everything towards the center of the star. It tries to compress the star into the smallest, tightest ball possible.

2. Thermal Pressure: This is the force that counteracts gravity. It is caused by the heat of the nuclear reactions at the core of the star, which creates pressure that pushes outward.

So, in a stable star like our Sun, these two forces are in balance. The gravitational force is trying to crush the star under its own weight, while the thermal pressure is trying to explode the star. The balance of these two forces is what determines the size of the star.
