Basically, anything that gets close enough.
Anything that falls into a black hole will be destroyed. Also, anything that falls into a black hole will increase the black hole's mass.
Basically none. No atom will survive the forces in a black hole. (However, all the mass that falls into the black hole will still be there.)
No. When matter falls into a black hole it simply increases the black hole's mass, giving it stronger gravity and a larger event horizon.
It stays there. Actually, it just falls forever.
As the planet is approaching a black hole due to the immense gravitational pull on the objects surrounding it, the planet revolves around the black hole until it falls into the black hole.
Anything that falls into a black hole becomes part of that black hole's mass, which makes the gravity stronger and causes the event horizon to grow larger.
A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
Probably the mass of the black hole would increase, just as when normal matter falls in.
According to current theory, a black hole, if it exists, begins its life full,and nothing that falls into it ever leaves it.
Yes. Matter falls into black holes all the time; the first known black hole was the "Cygnus X1" black hole, which was discovered by the X-ray emissions caused by matter being pulled off the companion star and falling into the black hole.
A black body absorbs most of the light that falls on it. A perfect black body will absorb all of the light but will radiate electromagnetic energy according to it's temperature according to plank's law. This is why we call a black hole a BLACK hole. It absorbs EVERYTHING which falls into it and not even light can escape.
The same as when anything falls into a black hole: as it spirals into the event horizon, much of its matter is converted to radiaton, and the rest of it is absorbed by the black hole, adding to its mass. The fact is we don't really know. Theoretically, black holes are spatial singularities that lie at the bottom of a massive gravity well. The only thing that escapes a black hole is radiation, and we believe that is the result of the destruction of what falls in.
