In equilibrium.

### What are the equal and opposite forces acting on your sun to keep it in equilibreum?

The sun is kept in equilibrium by the balancing forces of the outward pressure from the energy of the nuclear reaction of hydrogen into helium and the inward force of gravity. This state is called Main Sequence. However, the sun is not in perfect equilibrium because as the sun's core of hydrogen is depleted, the next layer out of hydrogen will begin undergoing a nuclear reaction, causing the sun to expand.

### What are two forces that act on the sun?

they two forces that are acting on the gases in the sun are megenetic feild pole and the ionized gas

### What two forces keep the sun in equilibrium?

God and.......er.....g....god. Yes god and god

### What would happen if the gravitational force was eliminated between the earth and sun?

The earth's constant orbit around the sun is caused by an equilibrium between two forces - the gravitational pull of the sun, and the earth's velocity acting at a right angle to it. If that gravitational pull was suddenly eliminated, the earth would continue onwards in a straight line.

### Why the earth is not thermal equilibrium with the sun?

because the earth and the sun is not in the thermal contact with each other that is why the earth &amp; the sun is not in thermal equilibrium.

### Why is earth not in thermal equilibrium with the sun?

because the earth and the sun is not in the thermal contact with each other that is why the earth &amp; the sun is not in thermal equilibrium.

### What force or forces act on a comet?

Nothing fuels a comet. They are just ice balls orbiting the Sun forever (until they run into something). By the way, the tails of comets do not stream out behind them. The tails of comets always point away from the Sun.

### What the force on the spacecraft and force on the moon?

There are various forces acting on them, but a few forces which significantly decide their motion are: 1. On moon: Gravitational force due to earth and sun 2. On spacecraft: Gravitational force due to earth, moon and sun

### Why the earth is not in thermal equilibrium with yhe sun?

To be in thermal equilibrium, it would have to have the same temperature. (It isn't.)

### Why earth is in motion and what external force is acting upon it?

If something is moving, no force is required for that something to continue moving. That doesn't mean there are no forces acting on Earth; for example, the Sun attracts Earth towards it. But that's not what keeps the Earth moving.

### Why earth is not equilibrium with sun?

While the earth and the sun are roughly at steady state (the output of the sun stays fairly constant and the earth absorbs the energy from it at a fairly constant rate) they are not in equilibrium. To be at equilibrium, they would have to be sending out and receiving equal amounts of energy and mass. The sun sends out far more energy than the earth as well as dumping a lot more mass, in the form of "solar winds" than the earth ever does - thus they are not in equilibrium.
