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.
2,042 Questions
Was the atomic bomb a success?
The atomic bomb successfully achieved its intended purpose of ending World War II by forcing Japan to surrender. However, its use has been highly controversial due to the massive loss of life and long-lasting impact on those affected by radiation.
Who is creator of atomic bomb?
The atomic bomb was created by a team of scientists led by J. Robert Oppenheimer at the Manhattan Project during World War II. Oppenheimer is often credited as the "father of the atomic bomb" for his leadership in the project.
Where did Albert Einstein create the atomic bomb?
Albert Einstein did not create the atomic bomb. The atomic bomb was invented by a group of scientists in the United States. The majority of the research and testing went on at the weapons research and design laboratory at Los Alamos, New Mexico. Einstein did, however, send a letter to president Roosevelt encouraging the United States to begin research on an atomic weapon, and many of Einstein's theories went into the creation of it.
The atomic bomb was not invented in the US, it was invented in London, England in 1933 by Leo Szilard and patented by him in 1934. However it took 12 more years, many scientists & engineers & technicians, and an enormous investment in new industrial infrastructure before the first atomic bombs could be built.
Is there fluoride in the atomic bomb?
Yes, fluoride is sometimes used in the production of nuclear weapons to help purify and enrich uranium for fuel or bombs. However, the amount of fluoride present in an atomic bomb itself is typically very small and not a primary component of the weapon.
How much power did the atomic bomb have?
The atomic bomb that was dropped on Hiroshima in 1945 had an explosive yield equivalent to approximately 15 kilotons of TNT. This explosion resulted in massive destruction and loss of life in the city.
Is unearthed uranium susceptible to reaction if it were exposed to an atomic bomb blast?
Unearthed uranium is not highly reactive to an atomic bomb blast on its own. However, if the uranium was refined and processed into a nuclear weapon, it could undergo fission reactions in response to a nuclear blast, contributing to the explosive power of the bomb.
The first atomic bomb used in warfare was dropped by the United States on the Japanese city of Hiroshima on August 6, 1945, during World War II. It was called "Little Boy" and it caused widespread destruction and massive loss of life.
Did the atomic bombs shorten the war?
The atomic bombs dropped on Hiroshima and Nagasaki in 1945 are believed to have contributed to Japan's surrender, thus potentially shortening the war in the Pacific. The devastation and casualties caused by the bombs, coupled with the Soviet Union declaring war on Japan, put immense pressure on Japan to end the conflict.
Who invented atomic bombs and how?
The atomic bomb was invented by a team of scientists led by J. Robert Oppenheimer as part of the Manhattan Project during World War II. The project was based in the United States and aimed to develop the first nuclear weapons. The first successful test of an atomic bomb took place on July 16, 1945, in New Mexico.
How is the law of conservation of energy related to the atomic bomb?
explosion of an atom bomb releases large amount of energy as heat liberation resulting rise in temperature and deformation in matter and pressure and many more forms of energy obtained from matter.
Diameter of destruction from atomic bomb?
Depends on the size of the bomb (they come in many different sizes- bigger is more destructive) and how high the bomb is above ground when it explodes. Most are set to explode when several hundred feet above ground.
Why was the first atomic bomb named the little boy?
The nickname of the first atomic bomb (the one set off in the Trinity test) was "the gadget".
Little Boy was the first atomic bomb designed but the one detonated; it was the one detonated over Hiroshima (so it was the first one anyone outside the Manhattan Project knew about). Little Boy was called that because of its shape: Fat Man (the third bomb, detonated over Nagasaki) and the gadget were nearly spherical, but Little Boy had a slim roughly cylindrical shape.
The reason the bombs had different shapes was that they were based on different technology. Little Boy used enriched uranium, which allowed for a simpler design but was harder to obtain than the plutonium used in the other devices (plutonium could be produced in breeder reactors from the more common isotope uranium-238, and it's much easier to separate two elements than to separate two isotopes of the same element).
The original plan was to use uranium for all the bombs, but the schedule only allowed time to produce enough enriched uranium for one. Rather than wait for more, they decided to try plutonium instead, and plan B was to make the same kind of bomb but with plutonium. However, testing revealed that wouldn't work: the plutonium started to go prompt-critical too quickly, and it was thought likely that the simple gun-target model used in the slimmer bomb would "fizzle" (go off too soon, with a much weaker explosion) if plutonium was used.
Enter plan C: instead of taking two big pieces of plutonium and shooting one at the other (using a conventional explosive), they took a bunch of pieces and shot them all together at the center. This kept the plutonium below critical mass longer and allowed time for all the plutonium to be assembled before prompt criticality started. However, the design was larger and more complicated and they weren't sure it would even work, hence the Trinity test (the Little Boy design wasn't even tested, at least not as a full-scale assembled bomb; the scientists involved were so sure it would work they didn't consider it necessary to test first).
How is the chain reaction in a nuclear reactor different from one in an atomic bomb?
In a nuclear reactor, the chain reaction is controlled to produce a steady flow of energy by regulating the rate of reactions. In an atomic bomb, the chain reaction happens rapidly and uncontrollably, resulting in a massive release of energy in a short period of time, leading to an explosion.
What is the difference between an atomic bomb and a nuclear weapon?
An atomic bomb is a type of nuclear weapon that releases energy through nuclear fission (splitting of atomic nuclei). Nuclear weapon is a broader term that encompasses atomic bombs, as well as hydrogen bombs which release energy through nuclear fusion (combining atomic nuclei).
Element used in first atomic bomb?
The first bomb exploded, the Trinity test bomb, used plutonium.
The first bomb deployed, dropped on Hiroshima, used uranium 235.
The second bomb deployed, dropped on Nagasaki, used plutonium 239.
How was the atomic bomb transported?
The atomic bomb was transported by air on board a specially modified B-29 Superfortress bomber called the Enola Gay or Bockscar. The bombs were loaded onto the planes at the airbase and flown to their target cities before being dropped.
Who discoverd the atomic bomb?
The atomic bomb was developed during World War II as part of the Manhattan Project. The project was spearheaded by the United States and led by scientists such as J. Robert Oppenheimer, who is often credited as the "father of the atomic bomb."
What is the destructive power of an atomic bomb?
An air burst (detonating a bomb above the surface) would produce far more damage and death via radioactive fallout than one detonating at ground level.
A single 100 megaton air burst would be enough to cause a nuclear winter and pollute the Earth for many many years. Theoretically, a 100 megaton bomb detonated below ground could produce a massive earthquake and the constant explosions of a full blown nuclear war may also cause numerous earthquakes around the globe. But this would not destroy the world nor all human life.
Globally there are not enough nuclear bombs to completely kill every human. The Tsar Bomb (largest bomb ever detonated) had a fallout of 1000 square kilometres, and was 50 MT. The world is close to 150 million square kilometres, and the human population covers close to 18 million square kilometres.
Therefore to get a rough idea we can say hypothetically that the 5000 megatones of nuclear warheads was 100 Tsar Bombs (the same value in megatons). If these bombs were detonated their total radioactive fallout would cover 100,000 square kilometres.
It may be surprising to hear that this covers less than 1% of the area that the human population covers, which should give a general idea of the miniscule size of impact this would have on the total world's surface. Therefore it can be shown that we do not have the capacity at the moment to destory the world with nuclear warheads.
However, there are factors we have overlooked, which include:
- Tsar Bomb has a very small radioactive fallout in comparison with its megatone value
- Nuclear wardheads can be assumed to target densly populated locations, and
- Nuclear winter which would result in the radioactive fallout
To put curiousty to rest, even if we replaced our Tsar Bomb equation with nuclear warheads that had a higher radioactive yield to fulfill the 5000 megatons gloabl nuclear arsenal we would still not come close to the amount of radioactive fallout required to cover the area the human population covers, let alone destroy the world.
If nuclear warheads were targeted at densly populated locations it would increase the fatalities of a nuclear war, however this would still not wipe out humanity, let alone destory the world.
Nuclear winter can in lamer terms be contrasted with the ice age. The ice age did not destory the world, and did not wipe out all life, therefore neither would nuclear winter. Humanity is extremley resilient, and although many of the world's population die due to starvation if they did not die from the initial nuclear war or radiation, life will find a way.
-----------------------------
You forgot to take into account the amount of radiation there would be if more than one detonated at a single time.
My U.S. History teacher told us that if 8 nuclear bombs went off at roughly the same time, it would kill 95% of life in planet Earth.
What does the atomic bomb have to do with Albert Einstein?
He played a role in its creation by sending a letter to convince president Roosevelt to start work on a nuclear weapon, and many of his theories went into the making of it. Einstein himself was a pacifist and regretted for the rest of his life that he had influenced the creation of nuclear weapons.
Why the us should not have dropped the atomic bomb on Japan?
Opinions differ on this.
The bomb did kill a lot of civilians. However, it was an order of magnitude fewer than the official US military predictions of the number of Japanese civilians that would have been killed in a conventional invasion, so in a sort of twisted way, the bomb was actually a more humane choice.
Why is the atomic bomb called Fat Man and Little Boy?
The difference was little boy was droped on Hiroshima in world war 2, it is much smaller than the fat man used on Nagasaki and the little boy uses uranium to compress it. The fat man uses plutonium to detonate.
Did Japanese think the atomic bomb was supernatural?
No, the Japanese did not think the atomic bomb was supernatural. They were aware of its devastating power and understood it as a powerful and destructive man-made weapon used by the United States during World War II.
Why did the US use Atomic bombs?
The US used atomic bombs on Hiroshima and Nagasaki in 1945 during World War II to bring a swift end to the war against Japan and avoid a prolonged and costly invasion of the Japanese mainland. The bombings were intended to show the devastating power of nuclear weapons and to force Japan to surrender unconditionally.
Where did the first atomic bomb land?
The first atomic bomb landed in Switzerland. Most people believe that it landed in Japan but there was actually one before that. >which of course landed in Switzerland
Was Truman right to drop the atomic bomb?
This is a copy of a summer project that I did for my school on why Truman should not have dropped the bomb, which I hope answers your question.
Dear President Truman:
As your most trusted advisor, and having explored all possible options, I have decided to strongly suggest that you NOT DROP the atomic bomb.
First and foremost, the bomb would kill millions of innocent people who do not care about the war. They have not provoked us in any way, and should not be harmed. These people do not participate in the war, even if they reluctantly send their fathers and husbands off to fight in the army. They are forced to do this by their government. The Japanese are not savage people, and should be considered a human being, just like everyone in the United States and the other countries.
Another reason to not drop the bomb is that we can avoid this, which I know you would prefer over dropping it. Through careful examination, I have come to the conclusion that we can show the Japanese what the bomb can do, just like we did in the test. Hopefully, they would surrender. They know that know we know how to build it, and we can make many more before they have a chance to strike.
A third and last reason for you not to drop the bomb is that it would deplete our stores of material, so we could not build any other thing, unless we raised the taxes very, very high. Making this bomb is very taxing on what we have in store, and I don't know how much will be left after it is dropped, if you decide it should be so. The people of the United States are sure to want you out of office if you raise the taxes. I'm sure that you'd like to be reelected for office, and this would make your chances of winning at about zero.
Truly, it would be a wise idea to not drop the atomic bomb for the reasons stated above.
