There have only ever been two nuclear devices used on anyone--one was dropped on Hiroshima, the other on Nagasaki. They worked on the principal that if you get enough fissionable material in the same place at the same time, you'll get a runaway chain reaction that will cause the material to explode. So they figured out how much was enough to do this, stuck half of it at each end of a long tube, and put a lump of explosive behind one of them. When they threw this bomb out the back of an airplane, a sensor in the bomb detonated the explosive. It forced the two pieces together and the resulting explosion leveled the city they dropped it on. This is way too expensive to do on a large-scale basis, and the only reason they did it was that they needed something to use Right Now and they didn't really know how to make good bombs. They've found out since then that if you squeeze the atoms in a piece of material really close together it will cause the same kind of runaway chain reaction, so that's what they do now--build a sphere out of uranium and put explosives around it. When you throw this out the back of an airplane and set it off, it squashes the ball of uranium, which causes a runaway chain reaction, then an explosion that levels the city they drop it on.

RafaA nuclear device works by initiating a chain reaction of nuclear fission, where atomic nuclei split into smaller particles, releasing a large amount of energy. This energy is harnessed to create an explosion with devastating force. Additionally, nuclear weapons can also use fusion, where atomic nuclei combine, in a thermonuclear reaction to release even more energy.

When was implosion style nuclear device tested?
The first implosion-style nuclear device was tested on July 16, 1945, as part of the Trinity test in New Mexico, USA. This test marked the first successful detonation of a nuclear weapon.
What is a device that converts thermal energy into work?
A device that converts thermal energy into work is called a heat engine. Heat engines take thermal energy from a heat source, such as combustion or nuclear reactions, and convert it into mechanical work through processes like expansion of gases or steam. Examples include steam engines and internal combustion engines.
Which type of nuclear burst occurs?
A nuclear burst can occur as a result of a nuclear explosion, which can be caused by either a fission or fusion reaction. The specific type of burst depends on the design and intent of the nuclear device used.
What is a nuclear reactor and what is its purpose?
A nuclear reactor is a device that initiates and controls a nuclear chain reaction to generate electricity or produce materials for nuclear weapons. Its main purpose is to harness the energy released during a controlled nuclear fission chain reaction to produce heat, which is then used to generate electricity in a nuclear power plant.
Percentage of energy that is used by a device to perform work is called?
The percentage of energy used by a device to perform work is called "energy efficiency." It is a measure of how effectively the device converts energy input into useful work output.
