The explosion of one ton of TNT releases approximatly 4.2 × 10 12 joules of energy; for comparison, it takes almost 6.0 ×10 4 joules to warm up a cup of coffee. The Trinity test, a plutonium fueled bomb had an estimated yield of 21 kilotons, and left a crater 2.9 meters deep and 335 meters wide.
What is the time elapsed in a nuclear detonation? : r/askscience - Reddit
2016年5月18日 · Nuclear bomb physicists use the timescale of a "shake" which is 10 nanoseconds. This is roughly the amount of time it takes for a fission generated neutron to traverse the core, and also the same time scale for which one "generation" of neutron mediated fission reactions spawns the next "generation".
