A very complex question, depending on its yield and dozens of other variables.
Several orders of magnitude more damage than conventional bombs, and that is only considering the blast and fire damage.
None
A single 1 MTon bomb will do it, or four 250 KTon bombs, or a thousand 1 KTon bombs, etc. However more smaller bombs can spread the damage wider than one large bomb.
Some bombs are nuclear. But most bombs are not nuclear.
Thermonuclear bombs, or hydrogen bombs, are more destructive than nuclear bombs because they involve a two-stage process: a fission reaction triggers a fusion reaction, resulting in a much larger explosion. This fusion reaction releases much more energy and is more efficient at converting material into energy compared to the fission reaction alone. As a result, thermonuclear bombs are typically much more powerful and devastating than traditional nuclear bombs.
No, China has several hundred nuclear bombs and has had bombs since 1964.
Beacause millions of lives were taken by the nuclear bombs
At this time the US builds no nuclear bombs. A small number of existing bombs are refurbished as needed.
A nuclear bomb has never been dropped. It was an atomic bomb that was dropped on the Japanese cities Hiroshima ans Nagasaki. An atomic bomb is a nuclear weapon. Nuclear bombs have much more impact than atomic bombs, and could potentially end the World if a nuclear war was started.
This question could be easily misconstrued. While atomic and nuclear explosion mean the same thing, and all atomic bombs are nuclear bombs, not all nuclear bombs are atomic bombs. The more powerful nuclear bombs are hydrogen bombs, and there is a very important fundamental difference between the two. ============================================================== A bomb is fission - the splitting of an atom H bomb is fusion - the joining together of atoms (and much more powerfull)
Yes, there is nuclear energy in nuclear bombs. It is released in a few microseconds when they are detonated.
Nuclear bombs before the 60s were referred to as atom bombs, because the term Nuclear hadn't been discover yet. Nuclear bombs today, are generally Hydrogen bombs, or fusion bombs. They are significantly more powerful, able to places about the size of Rhode Island. Atom bombs,which were mostly uranium and plutonium, lack the destructive power of Nuclear or Fusion bombs.
