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.

Why did the US make the atomic bomb?
To defend against the possibility of a Nazi atomic bomb, which if Germany succeeded in making it Hitler would order it used against Britain to force them to surrender. It was hoped the US might complete the atomic bomb first, but if not then shortly after so that Germany might also be attacked with them in retaliation for attacking England.
What 2 cities did the US drop atomic bombs on that finally led to the Japanese surrender?
Hiroshima and Nagasaki.
What was the target for the atomic bomb little boy?
The T shaped Aioi Bridge was the aim point in Hiroshima.
How many US troops lost in atomic bombing of Hiroshima?
There were 11 prisoners which died in the attack.
Why did the US use the atomic bomb on Japan?
the decision to drop the bombs caused the Japanese surrender. This prevented massive casualties on both sides in the Operation Downfall invasion of Japan and from an otherwise prolonged war.
How many people can die from an atomic bomb in 1 minute?
Cannot answer without much more information, as this depends on the yield of the bomb, altitude of the detonation, population density around ground zero, housing construction, cloud cover, weather, and many other variables.
A low yield bomb over an area of high population density may kill many more than a high yield bomb over an area of low population density. Cloud cover may reduce death rate. A high yield bomb over an area of very high population density on a cloudless day could produce many deaths!
How long did it take until the fire went out after the atomic bomb hit nagasaki?
Both the Hiroshima and the Nagasaki atomic bombs exhibited similar effects. The damages to man-made structures and other inanimate objects was the result in both cities of the following effects of the explosions:
A. Blast, or pressure wave, similar to that of normal explosions.
B. Primary fires, i.e., those fires started instantaneously by the heat radiated from the atomic explosion.
C. Secondary fires, i.e., those fires resulting from the collapse of buildings, damage to electrical systems, overturning of stoves, and other primary effects of the blast.
D. Spread of the original fires (B and C) to other structures.
The casualties sustained by the inhabitants of both cities were due to:
A. "Flash" burns, caused directly by the almost instantaneous radiation of heat and light at the moment of the explosion.
B. Burns resulting from the fires caused by the explosion.
- The Manhattan Engineer District, June 29, 1946-
This means that the actual fire from the bombs was consumed in a flash.
Who dropped the atomic bombs on japan?
The United States.
The US Army-Air Force dropped atomic weapons on the Japanese cities of Hiroshima and Nagasaki.
The Hiroshima bomb was dropped by a plane called the Enola Gay, piloted by Col. Paul Tibbets, on 6 August 1945.
The Nagasaki bombing occurred on 9 August 1945. Again, the bomb was delivered by the Enola Gay, this time piloted by Maj. Charles Sweeney.
These two bombings represent the only use of nuclear weapons during war, and brought about the surrender of the Japanese Empire, thereby ending World War II.
What did you call the atomic bomb that was drop over Hiroshima?
The bomb was code-named "Little Boy."
How much did the atomic bombs weigh that were dropped in japan?
Little boy - 9700 pounds
Fat man - 10,213 pounds
How fission and fusion bombs work?
Probably the best unclassified sources of this information are Richard Rhodes books: The Making of the Atomic Bomb and Dark Sun.
Why did U.S. drop the atomic bombs on Japan?
The US wanted Japan to surrender and end WW2. Because the Japanese bombed Pearl Harbour, the US wanted revenge.
How are nukes and atomic bombs created?
Reading Richard Rhodes books: The Making of the Atomic Bomb and Dark Sun will help you understand this.
What was written on on the Atomic bomb dropped on Japan?
There was no writting on this bombs. Regular Airman write on the bombs they are going to use but these bombs didn't go to regular man.
Why did president roosevelt authorize the development of the atomic bomb?
There were too many casualties in that war. they wanted to end it.
Was it right for America to use the atomic bomb on Japan'?
America was wrong in dropping the atomic bombs on Hiroshima and Nagasaki My main argument for why the United States should not have dropped the atomic bomb on Hiroshima and Nagasaki is because they killed an unnecessary amount of innocent civilians. Most of the people killed were civilians and not military personnel, which made the bombings immoral and were only dropped to scare them into surrendering even though their military had not been severely attacked. We all know that life is not always fair, but by dropping the bombs, America had an extremely unfair advantage. Battles were going back and forth how they always had until America decided to show its power and drop the atomic bombs. They were not, however, the only country with such a weapon, but it had not been used by another country because it was very possible to win without such an immoral weapon. In the Potsdam Declaration, we did not mention the atomic bomb. We told Japan that if they didn't surrender then we would destroy their military. It was not right for us to not tell them how drastic of a measure we were really willing to take. If they had known that we were considering dropping the bomb, they might have surrendered earlier and then no one would have died in the process. The bomb was not our only choice. We could have ended the war politically instead of militarily. By jumping to conclusions and quickly making decisions, we killed many people that did not need to be killed in order to end the war. "The stark fact is that the Japanese leaders, both military and civilian, including the Emperor, were willing to surrender in May of 1945 if the Emperor could remain in place and not be subjected to a war crimes trial after the war. This fact became known to President Truman as early as May of 1945. The Japanese monarchy was one of the oldest in all of history dating back to 660 B.C. The Japanese religion added the belief that all the Emperors were the direct descendants of the sun goddess, Amaterasu. The reigning Emperor Hirohito was the 124th in the direct line of descent. After the bombs were dropped on August 6 and 9 of 1945, and their surrender soon thereafter, the Japanese were allowed to keep their Emperor on the throne and he was not subjected to any war crimes trial. The Emperor, Hirohito, came on the throne in 1926 and continued in his position until his death in 1989. Since President Truman, in effect, accepted the conditional surrender offered by the Japanese as early as May of 1945, the question is posed, "Why then were the bombs dropped?" - John V. Denson America was right in dropping the atomic bombs on Hiroshima and Nagasaki One reason is because Japan probably would not have been so sudden to surrender otherwise. In the movie we watched, they talked about how the Japanese were very surprised when the emperor agreed to surrender. They were used to the fight 'till death idea and they followed it until after the bomb was dropped and they surrendered. The battles at Okinawa and Iwo Jima demonstrated how difficult it would have been if we had invaded Japan. They showed that many American's would die along with many Japanese. By dropping the bomb, America saved many of its own soldiers and quickly killed off the Japanese as well as ending the war more quickly than if they had battled. Another reason that it was good for the U. S. to drop the bomb was to keep from Russia getting involved. We didn't want them to take sides against us and turn our chances of winning the war and extending the war. By dropping the bomb, we showed Russia the amount of power we had so they would not get involved. If they had joined the war, there is a possibility that either more Americans died or we might not have ended the war and won. When Japan declined the Potsdam Declaration which was sent to them saying that if they did not surrender we would destroy their military, we knew we would have to begin what we declared we would do. Dropping the bombs didn't wipe out the entire military but it served more as a warning for what was to come if they didn't surrender. America had been firebombing other Japanese cities. Continuing this instead of dropping the bomb probably would have killed just as many people, so dropping the bomb was just a faster, more effective way of doing it. One final point is that by showing the world the effect of the bomb at this time prevented any other nations from using it later on. During the Cold War for example, if the USSR and the US hadn't known about the effects of the bomb, either one of them could have tried it out then, possibly altering the outcome of the Cold War.
When was the atomic bomb dropped on Nagasaki?
Three days after the bomb on hiroshima was dropped(August 9, 1945)
What is the link between an atom and an atomic bomb?
- an atom is the basic unit of a chemical element, it is composed of protons and neutrons in a tiny nucleus and electrons in an extended cloud around that nucleus.
- an atomic/nuclear bomb is a type of bomb that obtains its energy from reactions occurring inside the nucleus of the atoms, instead of from reactions occurring in the extended cloud of electrons as conventional bombs do.
the fatman atomic bomb used in ww2 weighed 5 tons, without its plutonium core it is only a 5 ton blockbuster conventional bomb having a yield just under 5 tons of TNT; with the plutonium core it is an atomic bomb having a yield of 22,000 tons of TNT. this is an increase in yield of 4,400 times, by using the energy of the nucleus instead of the electrons!
Does atomic explosion and nuclear explosion mean the same?
This question could be easily misconstrued. While atomic and nuclear explosion mean the same thing, and all atomic bombs are nuclear bombs, not all nuclear bombs are atomic bombs. The more powerful nuclear bombs are hydrogen bombs, and there is a very important fundamental difference between the two.
==============================================================
A bomb is fission - the splitting of an atom
H bomb is fusion - the joining together of atoms (and much more powerfull)
