It would create a mini nuclear explosion.
no because the ball is round and it would make no difference in what side you put it on because it has no sides
On Earth, no. Air resistance would slow the feather way down. However, dropped on somewhere without an atmosphere (like the moon), they would reach the ground at the same time.
Electrons would flow from the ground, into the positively charged object.
The stone would fall straight down from the release point, it would fall with steadily increasing speed, and when it hit the ground, it would stop falling. The rate at which its speed increased during the fall would be 32.2 feet per second faster every second.
Uranium U -235
They would both SPLAT on the ground at the same instant.
They would reach the ground at the same time and whoever dropped them would die of suffocation.
If you dropped a hamster on its back it would go into shock.
Being a metal Uranium would conduct electricity.
No nuclear energy, no nuclear weapons
Nothing interesting !
The Ice Would Be Crushed
it would hit the ground, even if it hit some one the terminal velocity of a coin is not enough to kill them, it would just hurt like hell.
If you were close to ground zero you would vaporize. Further out you would be horribly burned by the flash and the 500 mph wind would rip the skin off your bones. Further still you would be injured by flying debris and be radiated from blast and become violently ill til you died of radiation poisoning.
There would be another hole in the periodic table of the elements...
Uranium is a silvery-grey metal in both solid and liquid state, However on exposure to air it produces a black uranium oxide on its surface, which would happen much faster to liquid uranium than to solid uranium.
This mixing is impossible; liquid nitrogen become a gas. Possible formation of uranium nitrides.
