Nuclear Weapons

A nuclear explosion is the type of explosion that causes a mushroom cloud. The distinctive mushroom-shaped cloud is formed when the intense heat and energy of the explosion causes the surrounding air and debris to rise rapidly, creating the iconic cloud formation.

There have been over a thousand nuclear explosions on Earth since they were invented. If you know how to use Google Earth, the very first nuclear explosion took place at the Trinity test site at 33o40'38"N 106o28'94"W. Type these numbers into the "fly to" window (33 40 37 N 106 28 29 W)" If you find this and your map is facing north, you can also see a small crater just below and to the right. This is where 100 tons of TNT (Tri-Nitro-Toluene) were exploded to calibrate the first atomic bomb. The first atomic bomb used in war was dropped on the Japanese city of Hiroshima on August 6th1945. This was a uranium bomb. The second, and last used in war thankfully, was dropped on the Japanese city of Nagasaki 3 days later on August 9th. After that, many test explosions were detonated. The largest atomic bomb on Earth was detonated by the Soviet Union and was 57Megatons or the same as 57 million tons of TNT.

During the detonation of a nuclear bomb an enormous amount of energy is released as fission due to the splitting (fissioning) of atoms of uranium or plutonium. In the case of a simple nuclear weapon (such as those dropped on Japan during World War 2) this is where the explosion stops. In the case of a hydrogen bomb, also referred to as a thermonuclear weapon, the energy released by the fission is used to trigger the fusion of atoms of hydrogen, releasing energy in the same way that the sun produces energy.

It depends on the delivery mechanism. If dropped by a modern jet bomber, a nuke can acheive low supersonic speeds. If on a intercontinental ballistic missile, a nuclear weapon can reach speeds exceeding 15 times the speed of sound, or several thousand miles per hour.

The little boy was a gun-type weapon, so the term "core" in relation to modern implosion weapon pits is not the same.

In Little Boy, two subcritical masses of uranium were brought together. The target was a small set of uranium rings. These sat within a heavy target case with tungsten carbide neutron reflector within. The "bullet" was several larger rings backed by a tungsten carbide reflector and a pusher plate, fired down a long artillery barrel by a few bags of cordite. It's possible one or several small mechanical beryllium-polonium neutron generators were inserted into the target used, although not necessary with uranium. When the bullet and target were assembled, the assembly would be completely enclosed inside the tungsten carbide reflector, reflecting neutrons into the now supercritical mass. The weapon then explosively disassembled.

The Purity && The Shape

AND size density

Nuclear energy is created through a process called nuclear fission, where the nucleus of an atom is split into smaller parts. This process releases a large amount of energy in the form of heat, which is used to generate electricity in nuclear power plants. Uranium-235 and plutonium-239 are commonly used as fuel in nuclear reactors for this purpose.

The bomb would have to have a big enough yield to cover the whole city and be detonated in a spot where the bomb could have a larger reach, such as the center of the city.It destroys a whole city by using an extremely powerful blast, usually measured in megatons (meaning one million tons of TNT). It would completely annihilate anything within the blast radius, and the closer objects would completely disintegrate. The cloud of radiation (that could cause cancer) will spread to a much larger area and contaminate it seriously, rendering habitation in that area impossible for at least two years.

Nuclear power is very good source of energy to turn to.

The only problem is the storage of nuclear waste, that is left over after the nuclear reaction the power plant.

The energy obtained from the nuclear power plant is very clean burning and more KJ/mole energy.

No, Albert Einstein was not directly involved in the development of the hydrogen bomb. However, he was a signatory to the Russell-Einstein Manifesto, which called for nuclear disarmament and warned of the dangers of nuclear weapons.

The shock wave from an explosion causes the most damage by creating extreme pressure and pushing outwards in all directions, destroying structures and causing injuries. Explosions can also generate heat and produce flying debris that can cause additional harm.

The fission of one U-235 nucleus releases 200 MeV of energy, which is equal to 3.2 x 10-11 Joules. So to calculate the nuclear energy released per second from a known amount of U-235 you need to know the number of fissions happening every second. This can be calculated from the neutron flux in the reactor and the amount of uranium contained. It's not straightforward because the neutron flux has an axial and a radial variation that can change with time, but computer programs can deal with this and come up with an answer. This enables the designer to decide how many fuel assemblies will be required to produce a certain reactor output.

The release of a large amount of energy in a short period of time causes the greatest damage in an explosion. The shock wave generated by the explosion can damage structures, cause injuries, and lead to loss of life. Additionally, the heat and fire produced during an explosion can also contribute to the extent of damage.

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 destructive range of a large nuclear bomb can vary greatly depending on its size and design. A very large nuclear bomb could potentially cause devastation over a radius of several miles, leading to significant casualties and destruction of infrastructure. However, the exact reach would depend on many factors such as the specific yield, altitude of detonation, and surrounding geography.

Power is consumed and converted from one form to another form, and in the process, "work" is done. No form of power is "biodegradable." The question actually has no meaning. It is rather like asking "is love biodegradable?" Love is an abstract human creation that although it may have physical manifestations, has no way to be biodegraded. Such is the case with power - any kind of power.

Nuclear weapons derive their immense destructive power from the energy released through nuclear fission or fusion processes. These reactions convert a small amount of matter into energy following Einstein's famous equation E=mc^2, where a tiny amount of mass is converted into a significant amount of energy.

The weight of a nuclear bomb depends on the bomb. Deliverable nuclear bombs have been built with weights as small as 50 pounds to as large as 30 tons. The first hydrogen bomb built (Ivy Mike test Sausage device) weighed 54 tons, but was never intended as a deliverable bomb (including the cryogenic equipment needed to keep its deuterium-tritium fusion fuel liquid the complete setup weighed 82 tons).

The start-up time for nuclear reactors can vary depending on the type and size of the reactor. Generally, it can take several hours to several days for a nuclear reactor to start up and reach full power operation. The process involves gradually increasing power levels while ensuring safety and stability.
