    en.wikipedia.org/wiki/Mass-to-charge_ratio

    When charged particles move in electric and magnetic fields the following two laws apply: Lorentz force law: = (+),; Newton's second law of motion: = =; where F is the force applied to the ion, m is the mass of the particle, a is the acceleration, Q is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.

    This equation for ⁡ gives satisfactory agreement with experimental measurements for low electrolyte concentrations, typically less than 10 −3 mol/L. Deviations from the theory occur at higher concentrations and with electrolytes that produce ions of higher charges, particularly unsymmetrical electrolytes.

    The unified atomic mass unit (symbol: u) is equivalent to the dalton. One dalton is approximately the mass of one a single proton or neutron. [2] The unified atomic mass unit has a value of 1.660 538 921 (73) × 10 −27 kg. [3] The amu without the "unified" prefix is an obsolete unit based on oxygen, which was replaced in 1961.

  5. Microsoft Math Solver - Wikipedia

    en.wikipedia.org/wiki/Microsoft_Math_Solver

    Microsoft Math contains features that are designed to assist in solving mathematics, science, and tech-related problems, as well as to educate the user. The application features such tools as a graphing calculator and a unit converter. It also includes a triangle solver and an equation solver that provides step-by-step solutions to each problem.

  6. Mass–energy equivalence - Wikipedia

    en.wikipedia.org/wiki/Mass–energy_equivalence

    Mass near the M87* black hole is converted into a very energetic astrophysical jet, stretching five thousand light years. In physics, mass–energy equivalence is the relationship between mass and energy in a system's rest frame, where the two quantities differ only by a multiplicative constant and the units of measurement.

  7. Talk:Dalton (unit) - Wikipedia

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

    "Atomic mass unit" is rarely used in the scientific literature. It is, however, used in some contexts such as some primary schools. "dalton" and "Da" is the prevailing and most common name and symbol for this unit. "unified atomic mass unit" (not to be confused with "atomic mass unit") with its symbol "u" is less commonly used but accepted by SI.

  8. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    the statistical confidence interval or tolerance interval of the initial measurement; the number of significant figures of the measurement; the intended use of the measurement, including the engineering tolerances; historical definitions of the units and their derivatives used in old measurements; e.g., international foot vs. US survey foot.

  9. Orders of magnitude (mass) - Wikipedia

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

    The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name. 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 .
