An atomic bomb works by having a number of neutrons released from the nucleus, and these in turn will dislodge more neutrons from other atoms and so on. Provided the number of neutrons released continues to grow, a nuclear explosion will result.
A significant problem is in having enough neutrons released to start the chain reaction going. This will not usually take place with ordinary materials, and the starting material has to be made to release more neutrons than it would do naturally. This is done by compressing the start material, but as you know, trying to compress a solid is difficult. A spherical cage of conventional explosive (shaped charge) is the most common method.
Returning to the question, there is no single "equation". If you look up the work of folk like Richard Feynman, and J R Oppenheimer, you'll be better informed.
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
The differential pressure equation used to calculate the pressure difference between two points in a fluid system is P gh, where P is the pressure difference, is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the two points.
The equation for the electric field between two parallel plates is E V/d, where E is the electric field strength, V is the potential difference between the plates, and d is the distance between the plates.
The electric field between two plates is directly proportional to the potential difference across them. This relationship is described by the equation E V/d, where E is the electric field, V is the potential difference, and d is the distance between the plates.
A first order differential equation involves only the first derivative of the unknown function, while a second order differential equation involves the second derivative as well.
ordinary differential equation is obtained only one independent variable and partial differential equation is obtained more than one variable.
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
The electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond is the absolute difference between the electronegativity values of the two atoms. This is represented as A - B, where A and B are the electronegativity values of the two atoms.
EXTRA!!
fuzzy differential equation (FDEs) taken account the information about the behavior of a dynamical system which is uncertainty in order to obtain a more realistic and flexible model. So, we have r as the fuzzy number in the equation whereas ordinary differential equations do not have the fuzzy number.
