No. The bomb is the actual device that is dropped from a specific height in the air. The blast occurs before it hits the ground. I am sure you have seen pictures of the mushroom cloud. Well, the blast was before that. It was a bright flash that could blind a person.
the full range of an atomic bomb (not just blast range) is 20 square miles
9.5 square miles
epicenter, ground-zero
impossible
An atomic bomb has enough destructive force to annihilate an entire city. It can kill thousands of people in a single blast.
Lots of energy, in the form of radiation and a blast wave.
Scientists developed the atom bomb.
The superheated blast melted their internal workings shut.
mostly evaporation from the blast or subsequent radiation burns...............
Anything between vaporize them instantly to absolute nothing - all depending on distance to blast, size of bomb, type of blast(air/ground) and what kind of protection that was available.
Yes, it is!
That depends mostly on the instrumentation you want to collect data on the test blast. The bomb itself is cheap.
