The variable y is directly proportional to the variable x with proportionality constant ~0.6. The variable y is inversely proportional to the variable x with proportionality constant 1. In mathematics, two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio.
[4] [5] In this case, measurements of this chance event may be difficult to separate from measurements of the target events. A coincidence design must contain two or more measured channels for detecting a particle interaction which can be correlated with each other or the interaction in question over time, space, and/or the properties/products ...
In mathematical statistics, the concept has been formalized as the Zipfian distribution: A family of related discrete probability distributions whose rank-frequency distribution is an inverse power law relation. They are related to Benford's law and the Pareto distribution. Some sets of time-dependent empirical data deviate somewhat from Zipf's ...
Stouffer theorises that the amount of migration over a given distance is directly proportional to the number of opportunities at the place of destination, and inversely proportional to the number of opportunities between the place of departure and the place of destination. These intervening opportunities may persuade a migrant to settle in a ...
The chemical force was assumed to be directly proportional to the product of the active masses of the reactants. = [] [] This is equivalent to setting the exponents a and b of the earlier theory to one. The proportionality constant was called an affinity constant, k.
For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant. The law is named after Amedeo Avogadro who, in 1812, [ 2 ] [ 3 ] hypothesized that two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same ...
In mechanics and physics, simple harmonic motion (sometimes abbreviated as SHM) is a special type of periodic motion an object experiences by means of a restoring force whose magnitude is directly proportional to the distance of the object from an equilibrium position and acts towards the equilibrium position.
The osmotic pressure is proportional to the concentration of solute particles ci and is therefore a colligative property. As with the other colligative properties, this equation is a consequence of the equality of solvent chemical potentials of the two phases in equilibrium.
