A nuclear bomb can be made with any desired yield from about 10 tons to well over 50 megatons in one single bomb. These numbers are just for tested devices that worked, there is no theoretical upper limit on the yield of fusion based bombs.
About the same number of square miles as the island of Eugelab in Eniwetok atoll in the pacific used to have. In 1952 it turned from a coral island to a crater in the Ivy Mike 10 megaton test shot.
100-140 warheads of 5 kilotons to 250 kilotons
1 megaton TNT = 4.184 petajoules ( 4.184 x 1015 J )
A nuclear bomb is extremely powerful, and that's why there are many countries seeking to obtain this power. Since the US is such a "responsible" country, the president is only aloud to look at the directions of how to control our countries nuclear power when in an emergency. The power of a nuclear bomb is typically measured in kilotons or megatons. 1 megaton is the equivalent of 1 million tons of TNT (similar to dynamite) blowing up. The largest nuclear bombs were around 50 megatons, or 50 million tons (or 50 billion kilograms) of TNT. The smallest nuclear bombs were around 10 tons (yes, that is only 0.01 kiloton). Note that at this time (2013) no country stockpiles bombs either that large or that small (about 50 kilotons to 300 kilotons is currently typical). Also, a nuclear bomb is powerful enough to take out an entire city, while spreading deadly radioactive fallout throughout the area. There is still some leftover radiation in places like Hiroshima and the various above ground test sites.
Assuming you like Dorathy from the wizard of ozzie i would say u would need about 10000000000000000002 10 megaton bombs
124. Mostly 24 Megaton Warheads.
At this time the US builds no nuclear bombs. A small number of existing bombs are refurbished as needed.
No nuclear bombs were tested on Easter Island.
none, australia is not a nuclear power
Well, to my research there hasn't been any nuclear bombs, Aussie has built.
in many places
None
Russia has roughly 3500 nuclear warheads at the time of this writing and the number is slowly falling.
there were two types of nuclear bombs. A "gun type" bomb and an implosion type one with a plutonium core
No nuclear weapons from that era remain. The last MK-III bombs were recycled to make MK-4 or MK-5 bombs by the early 1950s.
