Atomic Bombs
Atomic bomb is an explosive device in which a large amount of energy is released through nuclear reactions. This makes an atomic bomb, more properly called a nuclear weapon, a much more powerful device than any conventional bomb containing chemical explosives. The first Atomic Bombs were used during World War 2 in 1945 by the US onto 2 Japanese cities.

Who worked on the atomic bomb?
US Scientists in New Mexico (the Manhattan Project) and Albert Einstein had a say in it as well. he thought that you could split the atom but a huge force would happen but he thought nobody would be stupid enough to try it out.
What year did the boxcar drop the atomic bomb?
August 9, 1945
The B-29 which dropped "fat man" (the second of two fission bombs) on Nagasaki, Japan was named 'Bocks Car', not the often misspelled 'boxcar'. The name was a play on words by the crew; the plane's commander was Captain Fred Bock.
Bock did not captain the flight which dropped 'fat man' however, that honor went to Charles Sweeney and his crew. Sweeney's crew and plane, 'the great artiste' was slated to fly the mission, but had been outfitted with observation equipment for the Hiroshima bomb run. The crews switched planes rather than reconfigure them. After the bombing, due to delays in the mission and other factors, Sweeney ran low on fuel and had to land in Okinawa (on fumes) rather than return as planned to Tinian.
The first bomb, 'little boy' was dropped on Hiroshima from the 'Enola Gay' on August 6, 1945.

wrong answer below (and 5500 kilometers would be pretty close to the center of the earth - at 6375KM. I don't think we've figured out how to drill that deep.)

The boxcar was actually a different bomb in itself. It was tested at area 51 some 5500 kilometers underground. It was actually felt 155 miles away in Las Vegas where they had to shut down the casino's due to dice rolling while the box car bomb was being tested.
The heat of the atomic bomb was said to be 1,000 degrees hotter than the surface of the sun which would be 8,200 degrees Celsius. That would incinerate any life form within 3 miles and would also melt stone/concrete.
What did the first A-bomb explosion look like?
The image is a poor quality photo of the explosion at the Trinity test on July 16, 1945 (the film got overexposed due to the brightness of the flash).
Whats the difference between an atomic bomb and a regular bomb?
In a non-atomic or chemical bomb, the energy providing the explosion comes from the breaking of chemical bonds and the joining of others. An example would be ANFO, Ammonium Nitrate / Fuel Oil, probably one of the most used chemical explosives today. During the explosion the nitrate reacts with the fuel oil to produce Nitrogen, CO2 and water along with heat and pressure.
In an atomic bomb the explosive energy is provided by the breaking of unstable elements, such as Uranium 235 which has a natural tendency to break down by the emission of neutrons, this is known as fission. If a large enough amount of the pure fissionable material is in contact, then it can reach critical mass as the neutrons released from one atom's decay cause two more atoms to decay, this proceeds exponentially. During fission a small amount of the mass becomes energy and using Einstein's equation, E=MC2 where E is the energy released, M is the mass converted and C squared is the speed of light squared, even a small amount of mass will release a large amount of energy.
The second type of atomic bomb is a fission bomb. In this bomb 2 atoms of Hydrogen are forced together to make an atom of Helium. This is the same atomic process that powers the sun. The fission reaction is started by a fusion bomb providing the high heat and pressure to cause the atoms to unite. Again when the two atoms unite a small amount of mass is exchanged for energy.
When and where was the first atomic bomb dropped in World War 2?
It was dropped on Hiroshima August 6, 1945. The second was August 9, 1945 on Nagasaki.
Where did the building of atomic bombs take place?
The a-bomb was built in Oak Ridge, Tennessee - just outside Knoxville.
-----------------------------------------------------------------------------------------------------------------------
All atomic bombs built in 1945-1947 were built in Los Alamos, NM. Oak Ridge, TN only supplied the oralloy (Oak Ridge "alloy": weapons grade 80% enriched uranium) while Hanford, WA supplied the plutonium and polonium. The Navy supplied cordite and high explosives. Sandia in Albuquerque, NM supplied the custom bomb casings and electronics. Later factories (e.g. PANTEX in TX, Rocky Flats in CO) were built to do the assembly.
Who invented the atomic bomb and the hydrogen bomb?
Leo Szilard invented the atomic fission bomb in 1933 in London while crossing a street. He applied for a patent on it in 1934 and was granted that patent (GB630726) in 1936, at which time the British Admiralty classified the patent to prevent Nazi Germany from seeing it, the patent remained classified until 1949. Szilard worked on the Manhattan Project at Los Alamos helping develop the atomic fission bomb.
It is unclear exactly who invented the hydrogen fusion bomb as it came up in many group discussions early in the Manhattan Project. Edward Teller liked to have people believe he was the inventor, but that is unlikely. However Teller became fixated on it (calling it the Super Bomb) to the point that he began to hinder other people's work on the atomic fission bomb and finally Oppenheimer had to limit Teller's access to others on the project (which Teller never forgave him for). Before the war ended Teller had completed a hydrogen fusion bomb design that he called the Classical Super but was not allowed to try building it. However in December 1945 and January 1946 a simulation of Teller's Classical Super design was run on the ENIAC, but it showed the design was an unworkable failure and serious work on hydrogen fusion bombs effectively died at that time (although Teller persisted at working alone on them in his spare time).
In 1949 a team working on atomic fission bomb improvements at Los Alamos developed an idea to improve the core compression of an atomic fission bomb (and thus its efficiency and yield) using a concept called "staging", where a small atomic fission bomb would be used to compress a second larger atomic fission bomb thus giving a much higher yield. However the team ran into problems developing the equations for a computational model of this design. They sent their mathematician Stanislaw Ulam to consult with Edward Teller on these equations. Teller immediately saw that this "staging" concept was the feature needed to get the high compression and temperature needed to finally make his hydrogen fusion bomb design workable. By 1950 working together Stanislaw Ulam & Edward Teller had invented the modern staged hydrogen fusion bomb design (usually called the Teller-Ulam configuration, although Teller kept trying to denigrate and diminish Ulam's contributions).
Note: H. G. Wells created the name "atomic bomb" for his 1914 science fiction novel The World Set Free, but did not have anything to do with their invention.
Which main countries are responsible for dropping the atomic bomb?
The United States in Japan during WW2.
What is the atomic bomb used for?
The atomic bomb was used to end the war between the U.S. and Japan. The U.S. also dropped it to test the bomb to see if it worked. When the bomb passed the test the U.S. told Japan that we will drop an atomic bomb; Japan refused to surrender and we dropped two bombs on them (Hiroshima and Nagasaki); that's when Japan surrendered.
In modern terms, atomic bombs (and all nuclear weapons) are political tools, with very little practical battlefield use. In some regards, they can be considered a "terror" weapon, as possession of nuclear weaponry provides the owner with a credible threat to wreck mass destruction upon an opponent. That is, the utility of nuclear weapons comes not from their use, but from the threat of their use. As such, they are classic political tools for use in international power relations.
This question is, unless I'm mistaken, unanswerable due to the rules that I have agreed to in order to do this task. Learning how to build a nuclear weapon, or nuke, is NOT something appropriate for all ages.
What were the names of the two atomic bombs dropped in World War 2?
Little Boy and Fat Man
Dropped from The Enola Gay and Bockscar
Who flew the plane that dropped the atomic bomb?
Paul Tibbets flew the Enola Gay and dropped the atomic bomb upon the Japanese city of Hiroshima whereas pilot Charles Sweeney flew Bockscar and bombed Nagasaki with a nuclear weapon .
What was one name of a bomb used in World War 2?
The name of the atomic bomb that was dropped on Hiroshima was "Little Boy".
In 1939 who wrote a letter to President Roosevelt about the atomic bomb?
He wrote a letter saying that he found a way to make a chain explosion with uranium
Did inventor of the atomic bomb commit suicide?
Although many people were involved in the development of the first atomic bombs, the man who first conceived of the nuclear chain reaction mechanism (in 1933) underlying the atomic bomb, and first foresaw its potential to be used as a weapon, was a Hungarian physicist named Leó Szilárd, who had fled to London to escape Nazi persecution. After discovering that uranium could carry such a nuclear chain reaction, he sent a letter (also signed by Albert Einstein) to U.S. President Franklin D. Roosevelt urging the government to create a research project to develop a nuclear weapons. The result was the Manhattan Project, which in 1945, exploded the world's first atomic bomb.
Leó Szilárd, along with many other scientists involved in the Manhattan Project, opposed the actual use of the atomic bomb in war, and hoped that by merely by showing the tremendous power of the bomb, they could force the surrender of Germany and Japan. He was horrified that the bombs were dropped on the cities of Hiroshima and Nagasaki. He did not commit suicide, but he did stop researching nuclear physics -- in 1947, two years after the bombings of Hiroshima and Nagasaki, he changed fields and became a molecular biologist. He continued to warn of the danger of nuclear weapons until his natural death in 1964.
What were some good and bad things about the atomic bomb technology wise?
the good things were. they tested out a neucleur wepeon and the bad things are killed loads of people the good things were. they tested out a neucleur wepeon and the bad things are killed loads of people
The most important reason is that if the Allies had not developed the atom bomb first, then the Axis powers would have done so. It was a race.
Shortly before Britain and France declared war on Germany, a letter was written by Albert Einstein (after prompting by some other physicists) for the attention of President Roosevelt of the USA detailing the possibility of using nuclear fission as a weapon. This letter stressed the urgency that this was developed before Nazi Germany did so and was actually delivered to the President after war had erupted in Europe.
It was eventually acted upon by the US government and the 'Manhattan Project' was set up. The very next day the Japanese attacked Pearl harbor and America was at war.
Once the atom bomb had been developed it was used to spare the lives of Allied soldiers who would have otherwise had to mount an invasion of the Japanese homeland to force their surrender (which would most likely have cost a large number of lives on both sides). Its use forced a speedy surrender by Japan and a resolution to the war. It can clearly be argued that this therefore actually saved many lives.
Of course the atom bomb was also used to demonstrate beyond all doubt to the world that the West now had a new weapon of immense power (but one would hope, and there is certainly no reason to believe otherwise, that the first reason was the primary one and that this second reason was merely a by-product). Of course, now the Russians saw the need to develop their own nuclear capability and so began an arms-race.
What was the first city to be bombed with an atomic bomb?
Hiroshima, Japan was the first city in history to suffer a nuclear attack on August 6, 1945. Nagasaki was attacked with a nuclear weapon three days later. These are the only two nuclear weapons used in anger.
Where was the first nuclear bomb tested?
Trinity was the first test of technology for an atomic weapon. It was conducted by the United States on July 16, 1945, at a location 35 miles (56 km) southeast of Socorro, New Mexico on the White Sands Proving Ground, headquartered near Alamogordo.
