What is a nuclear bomb?

Question

if albert instine created it how did he create it

Answer 1

A nuclear weapon is a weapon which derives its destructive force from nuclear reactions of fission or fusion. As a result, even a nuclear weapon with a relatively small yield is significantly more powerful than the largest conventional explosives, and a single weapon is capable of destroying an entire city.

In the history of warfare, nuclear weapons have been used only twice, both during the closing days of World War II. The first event occurred on the morning of August 6, 1945, when the United States dropped a uranium gun-type device code-named "Little Boy" on the Japanese city of Hiroshima. The second event occurred three days later when a plutonium implosion-type device code-named "Fat Man" was dropped on the city of Nagasaki. The use of these weapons, which resulted in the immediate deaths of around 100,000 to 200,000 individuals and even more over time, was and remains controversial — critics around the world charged that they were unnecessary acts of mass killing, while others claimed that they ultimately reduced casualties on both sides by hastening the end of the war. This topic has seen increased debate recently in the wake of increased terrorism involving killings of civilians by both state and non-state players, with parties claiming that the end justifies the means (see Atomic bombings of Hiroshima and Nagasaki for a full discussion).

Since the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over two thousand occasions for testing and demonstration purposes. The only countries known to have detonated such weapons are (chronologically) the United States, Soviet Union, United Kingdom, France, People's Republic of China, India, Pakistan, and North Korea. Various other countries may hold nuclear weapons but have never publicly admitted possession, or their claims to possession have not been verified. For example, Israel has modern airborne delivery systems and appears to have an extensive nuclear program with hundreds of warheads (see Israel and weapons of mass destruction), though it officially maintains a policy of "ambiguity" with respect to its actual possession of nuclear weapons. Iran currently stands accused by a number of governments of attempting to develop nuclear capabilities, though its government claims that its acknowledged nuclear activities, such as uranium enrichment, are for peaceful purposes. South Africa also secretly developed a small nuclear arsenal, but disassembled it in the early 1990s. (For more information see List of countries with nuclear weapons.)

Apart from their use as weapons, nuclear explosives have been tested and used for various non-military uses.

Answer 2

Even although nuclear bombs are highly strong , a unmarried bomb say dropped on birmingham could simply damage the centre of birmingham with the preliminary blast, after which the increasing surprise wave and entire out could intent extra harm out into the suburbs, with a restricting blast subject of a number of rectangular miles. However if a hydrogen bomb have been for use the the blast subject could be a number of instances higher nonetheless . I look to consider studying a army comparison of simply what number of nuclear bombs it could take to completely damage the whole UK,, it became out the the russians proposal that a blend of fifty hydrogen bombs and normal nuclear bombs could be greater than ample to show the whole united kingdom in to a burning cinder.

Answer 3

Uranium atoms being split by being bombarded by nuetrons will release a tremendous amount of energy. Einstein's e=mc2 was used by nuclear physicists (in particular Enrico Fermi) to control the split of the atoms (otherwise known as nuclear fission). At the time of the splitting of the atoms (sometime around 1942) some thought an uncontrolled nuclear reaction would occur, destroying the planet.

Answer 4

The nuclear bomb is a powerful bomb that can destroy any big metropolis.
Nuclear bombs are made of uranium and plutonium.
There are certain elements that are radioactive and make a chain reaction in a nuclear bomb when it is activated.
Once the nuclear bomb is activated a blast of radioactivity is made covering lots of kilometers, thus destroying everything in its path and rearranging any living things' molecules.

Answer 5

Without researching it i would say it is about creating the point when a plutonium atom is put under the pressure that get it to expends its full energy potential.from what i gather this happens when it is in-cased in the exact amount of an exact formula of very high explosive,that is why there is a double blast with the first being the high explosive and the second being the atomic reaction of the plutonium.

Answer 7

a weapon that america likes to brag about and make itself think that will defeat a country like Japan with it.The weapon that makes people think it will work on anyone that automatically an
entire military in that country will perish along with the people
(the weapon that has blinded America's true vision on a situation)

A nuclear bomb uses nuclear fusion which is from Uranium
and tritium.The electrons will move extremely fast and
cause a chain reaction releasig isatopes.This can crack an atom.
This will cause an explosian.

Answer 8

A nuclear bomb either forces the atoms of a heavy element (like plutonium) together, or splits the atoms apart. The former is fusion, the latter fision.

Answer 9

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. [citation needed] Both reactions release vast quantities of energy from relatively small amounts of matter.
