One of the first atomic bombs released energy equivalent to that of 20,000 tons of TNT explosive
How much mass was converted to energy by this explosion, given that 1000 tons of TNT produce 4.3 × 1012 J of energy. Incidentally, modern H-bombs have energy yields 1000 times as much! (c = 3.0 × 108 m/s)
