The atomic length scale is ℓ a ~ 10 −10 m and is given by the size of hydrogen atom (i.e., the Bohr radius, approximately 53 pm).; The length scale for the strong interactions (or the one derived from QCD through dimensional transmutation) is around ℓ s ~ 10 −15 m, and the "radii" of strongly interacting particles (such as the proton) are roughly comparable.
The scale length of a string instrument is the maximum vibrating length of the strings that produce sound, and determines the range of tones that string can produce at a given tension. It is also called string length .
Factor () Multiple Value Item 0 0 0 Singularity: 10 −35: 1 Planck length: 0.0000162 qm Planck length; typical scale of hypothetical loop quantum gravity or size of a hypothetical string and of branes; according to string theory, lengths smaller than this do not make any physical sense. [1]
where ε is the average rate of dissipation of turbulence kinetic energy per unit mass, and; ν is the kinematic viscosity of the fluid.; Typical values of the Kolmogorov length scale, for atmospheric motion in which the large eddies have length scales on the order of kilometers, range from 0.1 to 10 millimeters; for smaller flows such as in laboratory systems, η may be much smaller.
Scale length may refer to: Length scale (or "scale length"), a significant concept in physics used to define the order of magnitude of a system; Scale height (or "scale length"), a specific parameter in physics denoting the distance over which a quantity decreases by a factor of e; Scale length (string instruments), a measurement of the length ...
The Planck length is a distance scale of interest in speculations about quantum gravity. The Bekenstein–Hawking entropy of a black hole is one-fourth the area of its event horizon in units of Planck length squared.
Common scale utilized by Japanese companies for figures of anime characters, especially [citation needed] when the portrayed character is supposed to be young in age. The scale of a standard 4-stud × 2-stud Lego brick compared to the unit size of a standard house brick (9 × 4 + 1 ⁄ 2 × 3 inches). 1:6: 2 in: 50.80 mm
In physics, a characteristic length is an important dimension that defines the scale of a physical system. Often, such a length is used as an input to a formula in order to predict some characteristics of the system, and it is usually required by the construction of a dimensionless quantity, in the general framework of dimensional analysis and in particular applications such as fluid mechanics.
