Nuclear warheads are pretty flexible, and can be set to detonate in several ways, and in all mediums:
1. Underwater (e.g., ASROC)
2. Atmospheric (high altitude (EMP burst) or low altitude air burst over target
3. Contact / Terminal coordinates (e.g., GPS) detonation on land or at sea
4. Underground penetration and detonation
5. Timer set on device placed in any location
no
The bombs that were dropped on Hiroshima and Nagasaki were atomic bombs and not nuclear bombs and were designed to explode above the ground and not on impact.
No, China has several hundred nuclear bombs and has had bombs since 1964.
Some atomic bombs explode on impact, most explode in the air for maximum destruction caused by the explosion spreading out over a wider area.
No
Japan has no nuclear weapons.

yes
Nuclear plants don't explode, they melt down. Nuclear bombs (atom bombs) explode. There won't be any signs that a nuclear explosion is "about to occur"-- there won't be any warning unless defense computers recognize an incoming warhead missile. BUT, still, there won't be signs beforehand. Just look up the bombing of Japan.
Detonated means has caused to explode or has exploded. This is commonly used in reference to bombs and other nuclear weapons.
Some bombs are nuclear. But most bombs are not nuclear.
It will if it is fused for airburst. This is selected to maximize the area and severity of blast and thermal flash effects.
no
If you mean the bombs that explode is : βόμβες
Yes, there is nuclear energy in nuclear bombs. It is released in a few microseconds when they are detonated.
Beacause millions of lives were taken by the nuclear bombs
No, China has several hundred nuclear bombs and has had bombs since 1964.
At this time the US builds no nuclear bombs. A small number of existing bombs are refurbished as needed.
