How much mass was converted to energy in the Hiroshima bomb?

The amount of matter converted to energy in the atomic bomb dropped on Hiroshima was about 700 milligrams, less than one-third the mass of a U.S. dime. 6.3 x 1013 Estimated energy, in joules, released from the Hiroshima bomb, the equivalent of 15,000 tons of TNT.

How much TNT is the equivalent to the atomic blast that hit Hiroshima?

The explosive effect of each was equal to that of up to a few tens of thousand tonnes of the conventional explosive TNT. On this basis of comparison, the Hiroshima bomb was of about 15 kilotons – that is, of 15 thousand tonnes of TNT equivalent – and that at Nagasaki was of 25 kilotons (ca. 65 and 105 GJ respectively).

How many tons of TNT power was the explosion of the Fat Man bomb?

Released by the B-29 Bockscar, the 10,000-pound weapon was detonated at an altitude of approximately 1,800 feet over the city. The bomb had an explosive force (yield) of about 20,000 tons of TNT, about the same as the bomb dropped on Hiroshima.

How much energy does an atomic bomb release?

The first test of a fission (“atomic”) bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ). The first thermonuclear (“hydrogen”) bomb test released energy approximately equal to 10 million tons of TNT (42 PJ).

How many joules of energy did little boy release?

Little Boy and Hiroshima Little Boy was 10 feet long and 28 inches in diameter and weighed 9,700 pounds. In terms of its power, the Little Boy had an explosive force of 15,000 tons of TNT. [2] To note, 1 ton of TNT is equivalent to 4.184 × 109 Joules and is a conventional way of measuring energy.

Who dropped Little Boy?

How many joules of energy did Little Boy release?

Is Fukushima still leaking?

The accumulating water has been stored in tanks at the Fukushima Daiichi plant since 2011, when a massive earthquake and tsunami damaged its reactors and their cooling water became contaminated and began leaking. TEPCO says its water storage capacity of 1.37 million tons will be full around the fall of 2022.
