In older text books and teachers for that matter, state that Miranda (a moon of Uranus) was shattered by a massive impact, with the fragments reassembling and denser ones subsequently sinking to produce the current strange pattern.
However, the current theory is that Miranda's surface was formed early in it's life by tidal heating when it was captured by Umbriel, and NOT an impact.
The movement of broken apart rock is called erosion. Erosion occurs when weathered materials are transported away from their original location by agents such as water, wind, ice, or gravity. This process can lead to changes in the landscape over time, as sediments are deposited in new areas.
Possibly, depending on why the comet split apart to begin with. If the comet's nucleus heats up unevenly. Once broken apart, the gas would be released into space, and the fragments will each continue to move apart. Gravity would act to bring the fragments back together, but the mutual gravity of comet fragments would be VERY small.
true
base pairs are broken apart
Gas.

They hold together with the help of different forces than gravity. Therefore they are not influenced by gravity.
One way is that without gravity the earth and sun would fall apart because there is nothing else to hold them together.
Price guns are factory made, usually pieced together on an assembly line. If you're really curious about the inner workings, you could buy a price tagging gun and take it apart.
Gravity is an attractive force wich pulls everything together, however, the universe is being pulled apart and therefore graviy is not what is doing this. The force which is pulling the universe apart is dark energy wich is a repulsive force which pulls everything apart.
Fusion and Radiation
Dark matter is all around us, inside and out, is what holds the forces of gravity together, keeps it from flying apart.
The normal reaction to gravity is attraction. Gravity tries to pull the two objects closer together. A negative reaction would be that the two objects try to push apart. Sounds like science fiction.

Electrical forces would push them apart.
In order for that to happen, one object must be positive mass and the other one must be negative mass. Negative mass has never been observed yet, so gravity has never been observed to push objects apart.
The Sun... from the Sun? If you mean, what stops the Sun from breaking apart, it is held together by its own gravity.
