  2. Gravitational constant - Wikipedia

    en.wikipedia.org/wiki/Gravitational_constant

    pc ⋅ M⊙−1 ⋅ ( km / s) 2. The gravitational constant G is a key quantity in Newton's law of universal gravitation. The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton 's law of universal gravitation and in Albert Einstein 's theory of general relativity.

  3. G-flat major - Wikipedia

    en.wikipedia.org/wiki/G-flat_major

    Its relative minor is E-flat minor (or enharmonically D-sharp minor). Its parallel minor, G-flat minor, is usually replaced by F-sharp minor, since G-flat minor's two double-flats make it generally impractical to use. Its direct enharmonic equivalent, F-sharp major, contains the same number of sharps as the G-flat major key does flats.

  4. Gravity of Earth - Wikipedia

    en.wikipedia.org/wiki/Gravity_of_Earth

    The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation ). [ 2][ 3] It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given by the norm .

    The list of United States high-school national records in track and field is separated by indoor and outdoor and boys and girls who have set a national record in their respective events. While these records have been compiled for over 100 years, there are varying standards for these records. The National Federation of State High School ...

  6. Klein–Gordon equation - Wikipedia

    en.wikipedia.org/wiki/Klein–Gordon_equation

    The Klein–Gordon equation ( Klein–Fock–Gordon equation or sometimes Klein–Gordon–Fock equation) is a relativistic wave equation, related to the Schrödinger equation. It is second-order in space and time and manifestly Lorentz-covariant. It is a differential equation version of the relativistic energy–momentum relation .

  7. Dalton (unit) - Wikipedia

    en.wikipedia.org/wiki/Dalton_(unit)

    The dalton or unified atomic mass unit (symbols: Da or u) is a unit of mass defined as ⁠ 1 12 ⁠ of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. [ 1][ 2] It is a non-SI unit accepted for use with SI. The atomic mass constant, denoted mu, is defined identically, giving mu = ⁠ 1 12 ...

  8. Wafer (electronics) - Wikipedia

    en.wikipedia.org/wiki/Wafer_(electronics)

    Bottom right: completed solar wafers. In electronics, a wafer (also called a slice or substrate) [ 1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells . The wafer serves as the substrate for microelectronic devices ...
