k represents the unit prefix kilo-(10 3) [10] the Boltzmann constant, often represented as k B to avoid confusion; the angular wavenumber of the wave equation, the magnitude of the wave vector k; an integer, e.g. a dummy variable in summations, or an index of a matrix; an unspecified (real) constant; the spring constant of Hooke's law
More Magic Triangle image mnemonics in the style of a cheat-sheet for high-school physics – in the SVG file, hover over a symbol for its meaning and formula. This is a categorized list of physics mnemonics .
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
The table usually lists only one name and symbol that is most commonly used. The final column lists some special properties that some of the quantities have, such as their scaling behavior (i.e. whether the quantity is intensive or extensive ), their transformation properties (i.e. whether the quantity is a scalar , vector , matrix or tensor ...
Rates on a 15-year mortgage stand at an average 6.32% for purchase and 6.34% for refinance — up 3 basis point from 6.29% for purchase and 5 basis point from 6.29% for refinance this time last week.
"The kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 × 10 −23 when expressed in the unit J K −1 , which is equal to kg m 2 s −2 K −1 , where the kilogram, metre and second are defined in terms of h , c and ∆ ν Cs ."
