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.)
When an item is traveling at a constant speed what must be true about the forces acting on that object?
You can't tell anything about them from the speed alone. Constant speed aloneisn't enough to tell that there are no forces on the object. The best example isa planet in a circular orbit around the sun. Its speed is constant, even thoughthere's a substantial gravitational force between it and the sun.When an item is traveling at a constant speed and also in a straight line, thenthe forces acting on it must either be nonexistent or must add up to zero.
Are the forces balanced on Venus's?
No. If all forces acting on the planet were balanced and their sum were zero, then Venus would bemoving in a straight line. Instead, it's moving in a path that's nearly a perfect circle, because ofthe force of gravitation constantly attracting Venus and the sun toward each other.
What is an example of gravity acting on a moving object?
The sun's gravity keeping the earth in orbit around the sun.
Which has a greater effect on tidal forces?
The Moon has a greater effect on tides, on planet Earth, than the Sun. This is despite the fact that the gravitational attraction by the Sun is greater - the reason is that tidal forces depend on the CUBE of the distance.
For the sun to be stable the inward and outward forces within the sun must be?
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 & 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 & 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 the sun is not equilibrium with earth?
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.
