Atomic Bombs

An atomic bomb is an explosive device that obtains its energy from the atomic nucleus. it is equally valid to call it a nuclear bomb, and it can obtain this energy through either of the processes of fission and/or fusion. There are many ways an atomic bomb can be delivered to its target: aircraft, unguided rocket, guided missile, cruise missile, torpedo, depth charge, hand carried, landmine (the target comes to it), artillery shell, jeep/tripod mounted bazooka, etc. Atomic bombs were also proposed and tested for several peaceful uses: blasting for construction (e.g. highways, railroads, canals), oil industry (e.g. natural gas extraction, oil extraction from tar sands), spacecraft propulsion (Project Orion 1958 to 1963), etc.

A nuclear missile usually means a guided missile with an atomic bomb (aka warhead) as its payload, the guided missile is the means of delivering that atomic bomb to its target. However it is also possible in some circumstances to interpret nuclear missile as equivalent to nuclear rocket. A nuclear rocket uses a nuclear reactor to heat a gas (e.g. hydrogen) to propel the rocket, as usually visualized the payload of a nuclear rocket is a deep space probe of some kind (but it could just as easily be a manned spacecraft or an atomic bomb).

Depends on the size of the charge, how close you are to the blast, what type of bomb it it and where it goes off. If you're at ground zero you'll simply evaporate, then you get burns + radiation, then only radiation, then nothing. Oh, you might get hit by whatever shrapnel the blast might throw around too.

The bomb was not made in 1939. It was made in 1945 at the end of WW2. Oppenheimer did not make the bomb, a very large group of scientists and technicians made the bomb. Oppenheimer was the civilian head of the group. That is analogous to saying that a single person invented the rocket that took men to the moon.

Positives: The atomic bomb ended World War II by forcing Japan to surrender, saving potentially millions of lives that would have been lost in a full-scale invasion. It also demonstrated the power of nuclear weapons, potentially deterring future conflicts between major powers.

Negatives: The atomic bomb caused immense destruction and loss of life in Hiroshima and Nagasaki, leading to long-term physical and psychological effects on survivors. It also raised ethical concerns about the use of such a devastating weapon and sparked a nuclear arms race during the Cold War.

The plutonium used in the first atomic weapon (the Trinity Device) was processed at the Hanford Reservation site in Washington State.

The uranium used in the first actual bomb (Little Man, dropped on Hiroshima), was refined at Oak Ridge, Tennessee.

There was a race that involved US, UK, and Canada during World War II; they wanted to build an atomic bomb in fear that Nazi Germany would create them first. This project was called the Manhattan Project (1942 to 1946), the project was under the command of Major General Leslie R. Groves Jr. of the US Army Corps of Engineers. Einstein, Szilard, Fermi, and President Roosevlet were main people involved in this project.

No, Albert Einstein did not invent the atomic bomb. The atomic bomb was developed as part of the Manhattan Project during World War II by a team of scientists, including J. Robert Oppenheimer, Enrico Fermi, and others. Einstein's role was limited to signing a letter to President Franklin D. Roosevelt urging research into nuclear weapons.

It was known that there had been other diplomatic moves, made previously by Japanese emissaries through neutral nations, which intimated that Japan might surrender under certain terms that were unacceptable to America and its allies. But when nothing definitive was heard from the Japanese, plans proceeded to drop the second atomic bomb. The second mission was designated 'Special Mission No. 16.' A B-29 would carry 'Fat Man,' heavier than Little Boy and more complex. The primary target was Kokura. The secondary target was Nagasaki.

Niels Bohr urged the U.S. government to promote international cooperation and open communication on nuclear technology to prevent the escalation of an arms race. He believed that sharing scientific knowledge was crucial for ensuring global security and finding peaceful solutions.

• If the tested bomb had not worked it is likely they would have tried dropping the other bombs.
• If Japan had surrender prior to the dates the bombs were to be dropped then the bombs would not have been dropped on Japan.

An atomic bomb works by forcing two pieces of radioactive material together, resulting in a chain fission reaction. This reaction releases an enormous amount of energy in a very short time creating a massive explosion. Hence, atomic bombs are primarily dangerous because of their powerful blast wave and the extreme heat of the explosion. Additionally, radioactive particles are released into the air by the blast. These particles continue to emit dangerous gamma rays causing radiation sickness and water and food contamination.

Nuclear power plants do not hold enough radioactive material to create an explosion so there is NO POSSIBILITY of the plant exploding. However, if the plant were to be poorly maintained, a "melt-down" could occur. In this case, the nuclear reactions would become too hot for the enclosing structure to contain and the facility would begin to melt, causing fires and allowing the release of radioactive particles. It is very difficult to stop a melt-down and containment is the best solution. This is what happened at the disaster of Chernobyl in the Soviet Union (http://en.wikipedia.org/wiki/Chernobyl_disaster). No other such case has ever occured although there was a scare at Three Mile Island (http://en.wikipedia.org/wiki/Three_Mile_Island_accident).

The atomic bomb was developed during World War II as a means to quickly end the war and reduce the need for a land invasion of Japan. It was believed that using the bomb would force Japan to surrender and save American lives.

Cesium is not a typical material used in the construction of atomic bombs. The primary materials used in atomic bombs are uranium or plutonium. Cesium may be a byproduct of nuclear reactions in atomic bombs, but it is not a key component.

On August 6, 1945, at 9:15 AM Tokyo time, a B-29 plane, the "Enola Gay" piloted by Paul W. Tibbets, dropped a uranium atomic bomb, code named "Little Boy" on Hiroshima, Japan's seventh largest city. In minutes, half of the city vanished. According to U.S. estimates, 60,000 to 70,000 people were killed or missing, 140,000 were injuried many more were made homeless as a result of the bomb. Deadly radiation reached over 100,000. In the blast, thousands died instantly.

The city was unbelievably devastated. Of its 90,000 buildings, over 60,000 were demolished.

Atomic bombs release energy in two ways. One is a fission bomb where the nucleus of a large atom is split into smaller parts. The amount of energy in the original atom is greater than the energy stored in the small pieces. This is the energy released. Atoms larger than iron can release energy when they are split up. The other is fusion or thermonuclear. It is called "thermo" because it needs to be very hot for it to happen. This is where the nucleus of two small atoms like hydrogen (deuterium H-2 or Tritium H-3) are joined together. The energy of the single hydrogen atoms is greater than the combined pieces. This is the type of nuclear reaction that occurs in the sun that provides us with sunlight and warmth. Atoms smaller than iron can release energy when they are joined together. The energy released in both types of bomb comes from the atom's nucleus, therefore the word nuclear.

In a classical context, yes - an atomic bomb releases more energy than could by liberated through exothermic chemical reactions, and therefore the energy could be said to be created, since the classical law of energy conservation is violated.

.

In a quantum context, no - an atomic bomb converts potential energy, stored as mass in the nucleus of an atom, into kinetic thermal energy.

That depends on how close you are to ground zero, the name given in the 1940s to the position of the bomb when it detonates. It can kill by instantly vaporizing a person. It can severely burn someone, causing him to either die instantly, die after a period of suffering, or survive the burns and start recovering from them, only to suffer and die anyway from radiation sickness. Someone who is not close enough to get burnt could be killed by the pressure wave, either directly or by causing something to fall on him, like a building. Someone who is miles away but looking in the direction of the bomb when it detonates could be permanently blinded by the intense flash of light that occurs at detonation. Even miles away from ground zero someone could be bombarded with gamma radiation and not know it right away, but then die a slow painful death from radiation sickness. The cloud of radioactive fallout could be carried far away by the winds, causing people to die of radiation sickness many, many miles from ground zero. If someone's exposure to gamma radiation is minimal, it is possible to receive a survivable dose, although many survivors can end up having children with severe birth defects years later.

The temperature at the hypocenter of the atomic bomb in Hiroshima reached around 7,000 degrees Fahrenheit (3,870 degrees Celsius). This extreme heat generated a powerful fireball and caused widespread destruction in the city.

Yes, Albert Einstein signed a letter to President Franklin D. Roosevelt in 1939 warning about the potential of atomic weapons. While he did not conduct the research himself, he was aware of the theoretical calculations and implications of nuclear fission that could lead to the development of an atomic bomb.

The dropping of the atomic bomb on Hiroshima and Nagasaki by the United States in 1945 heightened tensions between the United States and the Soviet Union, leading to the start of the Cold War. The Soviet Union saw the bomb as a threat to its own security and began its own nuclear weapon program, escalating the arms race and competition between the two superpowers.

It explodes because it contains a critical mass of unstable atoms of a heavy metal such as Uranium-235 or Plutonium-239. When the nucleus of one of these large atoms is hit by a neutron, the atom splits into two medium-size atoms such as Barium and Krypton or Strontium and Xenon, and also releases 2 or more free neutrons and a burst of energy. This process is called Nuclear Fission. The free neutrons from one nuclear fission can then create more fissions, and a Chain Reaction is begun. More fissions release more neutrons which create more fissions which release even more neutrons, etc. If conditions are right, this chain reaction proceeds explosively to form a Nuclear Fission Bomb or "Atomic Bomb". If this chain reaction is slowed and controlled, then the nuclear fission produces heat energy which can be used to boil water in a Nuclear Power Plant. Rapid fission, nuclear bomb. Slow controlled fission, nuclear power plant.
