A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
A subcritical mass cannot sustain a nuclear chain reaction, it dies exponentiallyA critical mass can sustain a nuclear chain reaction, but it remains constant neither increasing nor decreasingA supercritical mass not only sustains a nuclear chain reaction but it increases exponentially until the mass explodesA nuclear fission bomb must become supercritical at some time in order to explode.
Dr. Abdul Qadeer Khan is a Pakistani scientist known for his role in Pakistan's nuclear weapons program. He is credited with leading the team that successfully enriched uranium to develop Pakistan's first nuclear bomb in 1998. While his work was primarily in the field of nuclear technology, his contributions in physics relate to the development of nuclear reactors and weapons technology.
These are the constituents of atoms. Nuclei are made up of protons and neutrons. Useful nuclear energy is only obtained from a few nuclei which can be made to fission and release energy. The two main ones are Uranium235 and Plutonium239.
In a nuclear power plant, the reactor produces nuclear energy which transforms to thermal energy, and this is then used to produce steam which is used in a conventional staem turbine/generating set to produce electricity
A peer is someone who is on equal standing with you, typically in terms of age, background, or experience. Peers often share similar interests and experiences, making it easier to relate to and connect with one another.

It gets its energy from the atomic nucleus.
The sun's energy is produced by nuclear ENERGY!!! im in school..lol
Nuclear fuels is not only bad for us, but for the enviornment. Some nuclear plants dump nuclear waste in rivers, oceans, lakes and ponds. This can kill and injure living organisms including us. It is not even good to bury it in the ground. Nuclear waste has to be specially desposed.

Prostitution is a social value, which can be seen to be a coping mechanism for men in order for the nuclear family to exist.
It makes the ribosomes which make proteins.
In our daily lives we interact with numbers when making calculations and timing.
They are not
Radiographers and radiologists, and scientists.
corresponding angles are the same size
