The processes (fission and fusion) that release energy in nuclear explosions complete in from about 10 microseconds to about 50 microseconds depending on the exact design used. How far a falling bomb might move in that time will depend on its velocity, but this distance will be insignificant compared to the diameter of the fireball.
No!
The Little Boy bomb, dropped on Hiroshima in 1945, used enriched uranium-235 as its fuel. This type of bomb is known as a uranium-based atomic bomb, and it functions through the process of nuclear fission.
An atomic bomb is a complete deliverable bomb, including all nonnuclear components. The nuclear core is a rather small part, typically between 2 to 3 inches in diameter that contains the fissile fuel that when made supercritical by conventional explosives in the bomb fissions and provides the energy to drive the actual nuclear explosion.
Nuclear bomb can mean either fission or fusion bomb. Hydrogen bomb means fusion bomb. The fusion bomb can be built with any yield one wants, just by adding more stages with more fuel. The fission bomb has a theoretical maximum yield that cannot be exceeded.
A hydrogen bomb is a nuclear weapon that releases a tremendous amount of energy through nuclear fusion by combining hydrogen isotopes. On the other hand, a car running on hydrogen uses a fuel cell that converts hydrogen gas into electricity to power an electric motor. While both involve hydrogen, they serve very different purposes and operate on different principles.
Depends on the bomb: Uranium, Plutonium, Lithium, and Hydrogen are the most common. Different bombs use different ones or different mixtures.
many, some are the fuel, some are in the electronics, some are in the case, etc. each has different purposes.
The 'uranium bomb' is an A-bomb and is a first generation nuclear weapon. The hydrogen bomb or H-bomb is a 2nd generation nuclear weapon and generally many times more powerful. 'H-bomb' can also refer to 3rd generation nuclear weapons that have an additional mass off uranium to provide further fuel, triggered by the 2nd generation fusion reaction; these are the most powerful. But recent studies show that the H-Bomb has more mass, therefore more energy, and therefore has more energy. So the H-bomb is more powerful.
In the test bomb, the material was plutonium. Plutonium was also used in one of the bombs dropped on Japan, Fat Man. Little Boy, the bomb dropped on Nagasaki, was made of uranium.
No, a reactor is operated at critical and a bomb at supercritical. Also reactors include safety shutdown systems that quickly make them subcritical stopping the reaction.However reactors can have steam explosions and hydrogen/oxygen explosions. These are physical and chemical explosions respectively, not nuclear.
Yes, fusion reactions occur in a hydrogen bomb, which is a type of nuclear bomb. The high temperatures and pressures generated by the fission reaction in the bomb can trigger fusion reactions between hydrogen isotopes. This fusion reaction releases a large amount of energy, contributing to the destructive power of the bomb.
Plutonium is the preferred fuel for nuclear bombs due to its greater efficiency in sustaining a nuclear chain reaction compared to uranium. Its higher fissionability and smaller critical mass make it the more suitable choice for achieving the explosive yield required in nuclear weapons.
