USA HISTORY

Detailed explanation-1: -A smallish atom bomb, like the one that destroyed Hiroshima, has the explosive power of some 15 kilotons of high explosive, or 30, 000, 000 pounds. So something like thirty million sticks should work fine, if you can figure out a way to make them all go off at once.

Detailed explanation-2: -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.

Detailed explanation-3: -An overpressure of 230 kPa (33.4 psi) corresponding to detonation of 1 kg of TNT generates a blast wind of over 240 km/h measured near the point of origin. The mechanism of injury may be predicted by an individual’s distance from a detonation.

Detailed explanation-4: -The bomb was dropped on Hiroshima, Japan, August 6, 1945, at 8:15 AM. A B-29 dropped the bomb from 31, 000 feet. The bomb exploded about 1, 500 feet above the city with a force of 15, 000 tons of TNT. The name of the plane was Enola Gay, named after the pilot’s mother.
