  2. Action at a distance - Wikipedia

    en.wikipedia.org/wiki/Action_at_a_distance

    Action at a distance is the concept in physics that an object's motion can be affected by another object without the two being in physical contact; that is, it is the concept of the non-local interaction of objects that are separated in space. Coulomb's law and Newton's law of universal gravitation are based on action at a distance.

    ~5 mm Length of an average flea is 1–10 mm (usually <5 mm) [27] 2.54 mm One-tenth inch; distance between pins in DIP (dual-inline-package) electronic components 5.70 mm Diameter of the projectile in 5.56×45mm NATO ammunition 10 −2: 1 centimeter 20 mm Approximate width of an adult human finger: 54 mm × 86 mm

  4. Angstrom - Wikipedia

    en.wikipedia.org/wiki/Angstrom

    Portrait of Anders Ångström [15]. In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight, in which he expressed the wavelengths of electromagnetic radiation in the electromagnetic spectrum in multiples of one ten-millionth of a millimetre (or 10 −7 mm.) [16] [17] Ångström's chart and table of wavelengths in the solar spectrum became widely used in ...

    The spacing of the fringes at a distance z from the slits is given by = = / For example, if two slits are separated by 0.5 mm (d), and are illuminated with a 0.6 μm wavelength laser (λ), then at a distance of 1 m (z), the spacing of the fringes will be 1.2 mm.

  6. Absement - Wikipedia

    en.wikipedia.org/wiki/Absement

    For example, opening the gate of a gate valve (of rectangular cross section) by 1 mm for 10 seconds yields the same absement of 10 mm·s as opening it by 5 mm for 2 seconds. The amount of water having flowed through it is linearly proportional to the absement of the gate, so it is also the same in both cases. [5]

  7. Paschen's law - Wikipedia

    en.wikipedia.org/wiki/Paschen's_law

    The voltage required to arc this distance is 327 V, which is insufficient to ignite the arcs for gaps that are either wider or narrower. For a 3.5 μm gap, the required voltage is 533 V, nearly twice as much. If 500 V were applied, it would not be sufficient to arc at the 2.85 μm distance, but would arc at a 7.5 μm distance.

  8. Principle of locality - Wikipedia

    en.wikipedia.org/wiki/Principle_of_locality

    In physics, the principle of locality states that an object is influenced directly only by its immediate surroundings. A theory that includes the principle of locality is said to be a "local theory". This is an alternative to the concept of instantaneous, or "non-local" action at a distance.
