It stays there. Actually, it just falls forever.
Probably the mass of the black hole would increase, just as when normal matter falls in.
A planet that falls into a black hole would get completely destroyed. Its mass would be added to the mass of the black hole.
If the glass has a hole in the bottom and you submerge it upside down in water, the water would enter the glass through the hole until the air pressure inside and outside the glass equalize. Once this happens, the water would stay at a level inside the glass equal to the height of the water outside the glass.
The energy leaves as either a photon or phonon.
As it gets close it will be torn apart, then when it falls past the event horizon the bits will disappear from our sight.
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.
Alice falls down a rabbit-hole and ends up in Wonderland.
Yes, but not with the usual drill bit. Drilling a hole in glass is accomplished with an abrasive that actually wears a hole through the glass.
Just the same as if normal matter falls in. The matter or antimatter will stay there, increasing the mass of the black hole (and making it more "hungry", i.e., making its gravity stronger).
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.
