For a non-rotating black hole, a person (or a building, or a planet) would be pulverized and crushed into the singularity (point of infinite density) at the center of the black hole. However, the acceleration of particles is so great that a small black hole might cease to exist by the time the atoms actually reach the center, due to time dilation.
If you jumped into a black hole, you would be stretched into human spaghetti.
nothing
The black hole's mass would increase by an insignificant amount.
As you get near a black hole, the force of gravity is much stronger on the side of you nearest the black hole - so much so that your body (or anything else) is ripped into individual molecules. That means that your body cannot travel through a black hole . . . a bunch of molecules is no longer a body.
You would die
Should Earth ever collide with a black hole, it would get destroyed.
If atomic bombs entered a black hole, they wouldn't be able to detonate; instead, they would initially be stretched and crushed, and as they travel beyond the event horizon, they would be converted into gravitational energy. However, if you wereable to manage to get 5000 atomic bombs inside a black hole and detonate them, nothing would happen. The black hole would continue to exist as it always had; it would just be 5000-atomic-bombs-worth-of-weight heavier.
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
You would have a black hole the size of the combined mass of the two black holes.
You would die.
One does not simply "pass through" a black hole.
Gone.
