  2. Earth mass - Wikipedia

    en.wikipedia.org/wiki/Earth_mass

    An Earth mass (denoted as M 🜨, M ♁ or M E, where 🜨 and ♁ are the astronomical symbols for Earth), is a unit of mass equal to the mass of the planet Earth.The current best estimate for the mass of Earth is M 🜨 = 5.9722 × 10 24 kg, with a relative uncertainty of 10 −4. [2]

  3. Normalized number - Wikipedia

    en.wikipedia.org/wiki/Normalized_number

    Thus, a real number, when written out in normalized scientific notation, is as follows: ± d 0 . d 1 d 2 d 3 ⋯ × 10 n {\displaystyle \pm d_{0}.d_{1}d_{2}d_{3}\dots \times 10^{n}} where n is an integer , d 0 , d 1 , d 2 , d 3 , … , {\textstyle d_{0},d_{1},d_{2},d_{3},\ldots ,} are the digits of the number in base 10, and d 0 {\displaystyle ...

  4. Isotopes of neon - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_neon

    The abundances of the naturally occurring isotopes of neon. Neon (10 Ne) possesses three stable isotopes: 20 Ne, 21 Ne, and 22 Ne. In addition, 17 radioactive isotopes have been discovered, ranging from 15

  5. Standard atomic weight - Wikipedia

    en.wikipedia.org/wiki/Standard_atomic_weight

    This range is the rationale for the interval notation given for some standard atomic weight values. Of the 118 known chemical elements, 80 have stable isotopes and 84 have this Earth-environment based value. Typically, such a value is, for example helium: A r °(He) = 4.002 602 (2).

  6. Orders of magnitude (magnetic field) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude...

    This page lists examples of magnetic induction B in teslas and gauss produced by various sources, grouped by orders of magnitude.. The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface).

  8. Attenuation coefficient - Wikipedia

    en.wikipedia.org/wiki/Attenuation_coefficient

    The attenuation coefficient of a volume, denoted μ, is defined as [6] =, where Φ e is the radiant flux;; z is the path length of the beam.; Note that for an attenuation coefficient which does not vary with z, this equation is solved along a line from =0 to as:

  9. Shear modulus - Wikipedia

    en.wikipedia.org/wiki/Shear_modulus

    The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke's law: . Young's modulus E describes the material's strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height),
