What is the bomb?

Answer 1

Basically a nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.

A nuclear bomb also known as an atomic bomb. This is a bomb where nuclear fission is the sole source of the energy for the explosion. This explosion occurs when uranium235 and/or plutonium239 is transformed from a subcritical mass to a supercritical mass very rapidly, when a few neutrons are then fired into that supercritical mass the chain reaction continues and cascades at an exponentially increasing rate until it results in a huge explosion. However such fission only bombs have a theoretical limit to their yield of under 1 megaton.

If fusion is involved somewhere in the bomb, hydrogen nuclei (typically deuterium and tritium) fuse. By use of multiple fusion stages the yield of such bombs can be increased without theoretical limit.

Some very high yield fusion bombs are enclosed in a shell of uranium238 which will not normally fission, however the very high energy fusion neutrons can cause it to fission. This one feature can provide as much as 90% of the bomb's total yield, but also increases fallout by a similar amount.

Answer 2

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter. The first fission ("atomic") bomb test released the same amount of energy as approximately 20,000 tons of TNT. The first thermonuclear ("hydrogen") bomb test released the same amount of energy as approximately 10,000,000 tons of TNT.

A modern thermonuclear weapon weighing little more than a thousand kilograms (2,200 pounds) can produce an explosion comparable to the detonation of more than a billion kilograms (2.2 billion pounds) of conventional high explosive. Thus, even single small nuclear devices no larger than traditional bombs can devastate an entire city by blast, fire and radiation. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major focus of international relations policy since their debut.

In the history of warfare, only two nuclear weapons have been detonated offensively, both near the end of World War II. The first was detonated on the morning of 6 August 1945, when the United States dropped a uranium gun-type device code-named "Little Boy" on the Japanese city of Hiroshima. The second was detonated three days later when the United States dropped a plutonium implosion-type device code-named "Fat Man" on the city of Nagasaki, Japan. These two bombings resulted in the deaths of approximately 200,000 Japanese people (mostly civilians) from acute injuries sustained from the explosion. There is current debate over the atomic bombings of Hiroshima and Nagasaki.

Since the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over two thousand occasions for testing purposes and demonstration purposes. A few states have possessed such weapons or are suspected of seeking them. The only countries known to have detonated nuclear weapons---and that acknowledge possessing such weapons---are (chronologically) the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea. Israel is also widely believed to possess nuclear weapons, though it does not acknowledge having them.

Answer 3

Ok, u must be stupid!!how do u not know what a bomb is?!?! a bomb is a device that blows up, you know, something that goes booom

Answer 4

any atomic bomb is radioactive, by definition
