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.

How many atomic bombs were made during ww2?
Three, one that was tested in the US, one was deployed at Hiroshima and the third at Nagasaki. Bombs were under construction, but no further weapons were ready for use by the surrender date. A fourth bomb was made by Los Alamos before Japan agreed to surrender, but did not arrive in San Francisco to be flown across the Pacific until August 18, four days after the Japanese agreed to surrender (but before the formal signing of the agreement which happened in September). This is confirmed by declassified documents obtained by Chuck Hansen via FOIA requests and summarized in his work Swords of Armageddon.
As 3 more bombs were scheduled for production and delivery in September (ibid.) it is almost certain that Los Alamos completed the first of these 3 within a few days before or after the formal signing. However documents on the completion date of this bomb have not been released. If they did complete this bomb prior to the signing, this would make five in total were built during WW2.
The next definite data in Swords of Armageddon gives bomb production up to the end of the 1946 Operation Crossroads: total bombs built 9, total bombs detonated 5, bombs remaining in stockpile 4.
Note: bombs of this era when built were not assembled. for example a MK-III Fatman came in two crates of parts and took 3 days of final assembly in the field before use.
What were the consequences after dropping atomic bomb?
The previous response was opinion based, and also very uninformative since the bomb DID have major consequences and of course some advantages.
Consequences:-Long term effects of radiation from the bombs still continue to kill thousands.-Many innocent civilians wore the punishment of their rulers who decided not to surrender until after the bombs were dropped. The innocent civilians who died had no influence on the decision of their rulers.-It brought fear, fear of nuclear war.-Power usually causes corruption, and in this case - a whole lot of power was created (having the weapon = power, and now many countries have it).
I'm sure there are plenty of more consequences... but that's all I can think of right now.
Advantages:-It saved the lives of American soldiers (at the cost of innocent civilian lives, since most of the bombed cities, Hiroshima and Nagasaki, consisted of civilians).
- according to American military estimates, the bomb would have only saved fewer than 50,000 American lives; President Truman claimed 500,000 American lives would have been saved.
-It ended the war quickly.
Obviously, the consequences outweigh the advantages.
I hope this helps! I'd add more if I had more time...
Note: I tried to present the facts rather than give a biased opinion, but I'm sure you can tell which side I'm on.
Ethical issues of atomic bombs?
Nuclear Weapons keep nations at bay (the cold war). Neither side wants to use them. But they will if they think their survival demands it.
It blew people to bits stopping the war. And looked cool... Along with making the U.S. seem stronger.
How many people died from the atomic bombs blast alone?
I believe it was around 120,00 in 2 seconds from the blast, and around 60,000 after the blast from radiation poisoning.
Why was it not necessary for the US to drop the atomic bomb?
Yes!! It was nessasary because if we did not, they would not have surrendered!!!! We ended the war. It FORCED Japan to surrender due to all the deaths and war cost that would have had to be payed if any more was damaged.

It was entirely unnecessary. Japan was ready to surrender, but we were pushing them to surrender unconditionally. They thought that meant we wanted to depose their emperor, whom they believed was a descendent of their sun goddess, and they could not let that happen. If we had just let them have that condition, we would not have "had" to commit the unspeakable horrors that took place.
Of course it was neccesary. Basically, a land invasion would've cost waaay more lives than the nuclear bombs did. So all of you who thinks US is a scumbag country, fawk off. They did just the right thing. The japs were warned before both bombs. They were told to surrender, and they didn't. So they got it the hard way, in the least devastating one.
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.
