How Do Nuclear Bombs Work?

 10 months ago - 3 answers

Scowan
Nuclear bombs work on account of the energy generated from radiated particles. The reaction is extremely fast and therefore causes massive destruction. The two nuclear reactions fission and fusion can cause a nuclear explosion. Fission breaks nucleus apart and fusion makes them fall into one another. Plutonium and uranium are effective for fission bombs because they are radioactive and splitting them generates the required energy, while lighter elements like hydrogen are useful for fusion bombs (i.e. The hydrogen bomb in World War 2). Fusion bombs are somewhat less efficient.A nuclear bomb must have a shell to hold it – this will increase its effectiveness. It needs a trigger mechanism and the nuclear components (e.g. Plutonium, uranium or hydrogen). A supercritical mass must be reached which  read more...

How Does Evolution Work?

Scowan
As a species lives on generation through generation, their inherent attributes change. This, in a very basic sense, is evolution. This happens due to natural variation and selection as the species reproduces and passes on its genes; its blueprints. These genes contain the inherent attributes that allow for the process of evolution: When a species reproduces, the next generation might have slightly different – or even completely different – attributes. This is because the genes can mutate – or the genes might even have been passed on to a different species. Variation can also be increased due to genetic recombination: Different or even completely new gene combinations can arise in sexually reproducing species. And when these inherited differences become either increasingly common or increasingly  read more...

Origins and Composition
As a term, Napalm is often referred to by a French word, namely “portmanteau.” A portmanteau is simply the combination of two separate words, which are then abbreviated in order to form a single term. As such, Napalm is a combination of the words naphthenic and palmitic, both of which are acids.These acids were present in Napalm when this gel-like substance was first  read more...
