  2. Chandrasekhar limit - Wikipedia

    en.wikipedia.org/wiki/Chandrasekhar_limit

    This yields a polytrope of index 3, which has a total mass, M limit, depending only on K 2. [9] For a fully relativistic treatment, the equation of state used interpolates between the equations P = K 1 ρ 5/3 for small ρ and P = K 2 ρ 4/3 for large ρ. When this is done, the model radius still decreases with mass, but becomes zero at M limit.

  3. Multiple myeloma - Wikipedia

    en.wikipedia.org/wiki/Multiple_myeloma

    Multiple myeloma is diagnosed based on blood or urine tests finding abnormal antibody proteins (often using electrophoretic techniques revealing the presence of a monoclonal spike in the results, termed an m-spike), bone marrow biopsy finding cancerous plasma cells, and medical imaging finding bone lesions. [6]

  4. Orders of magnitude (mass) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(mass)

    The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg.

  5. Moment magnitude scale - Wikipedia

    en.wikipedia.org/wiki/Moment_magnitude_scale

    The moment magnitude scale (MMS; denoted explicitly with M or M w or Mwg, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. M w was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.

  6. NAVAIR Spike - Wikipedia

    en.wikipedia.org/wiki/NAVAIR_Spike

    The reduced-smoke motor propelled the missile from the launcher with a barely visible smoke trail, accelerating the missile to 600 mph (970 km/h; 270 m/s) in under 1.5 seconds. [7] On 12 April 2006, the Spike was launched at a 2-meter diameter target from 1,000 meters, impacting 8 in (200 mm) from the center. [8]

  7. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    It is first determined whether M is indeed greater than 1.0 by calculating M from the subsonic equation. If M is greater than 1.0 at that point, then the value of M from the subsonic equation is used as the initial condition for fixed point iteration of the supersonic equation, which usually converges very rapidly. [ 8 ]

  8. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...

  9. Orders of magnitude (magnetic field) - Wikipedia

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

    Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance (⁠ 1 / distance 3 ⁠) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]
