As with most questions about black holes, there's not really a simple answer to that.
In practice, if you dropped an actual clock (or any other material object) into a black hole, tidal forces would tear it apart long before it reached the event horizon, let alone the singularity.
From the point of view of an outside observer (which is what I assume you're interested in), the clock would appear to be running slow before it was torn apart. If we imagine a magic clock with infinite tensile strength, it would appear to get slower and slower as it approached the event horizon, and would finally stop just as it reached the horizon.
The penny will be gone. You will also be gone with it, because getting close enough to a black hole to drop a penny inside it will catch you in its gravity well.
Add again water.
It would get what ever is in it loss if nobody knew it dropped
It is absolute zero and all molecular motion stops
You would have a black hole the size of the combined mass of the two black holes.
If you dropped a hamster on its back it would go into shock.

The Ice Would Be Crushed
They would both float if you had no gravity.

Big boom!!
it explodes
It would create a mini nuclear explosion.
The feather would reach the earth first dumb@$$
THEY BURST
they would hit the surface at the same time, same as on earth.
The ball would roll downhill.
