Formulae. 1  Eclipsing binary: diameter = speed Ã time of eclipse. 2  Size from luminosity: star's radius/Sun's radius = (Sun's temperature/star's temperature)2 Sqrt[star's luminosity/Sun's luminosity].
MOA is a mathmatical concept that most firearm scopes incorporate. Minute of Angle (MOA) is critical to sighting in your scope. MOA mathematical concepts were used to develop the AccuScope scope sighting reference tool. The only MOA information needed to use AccuScope is your scope's MOA number.
MoCA, which stands for âMultimedia over Coaxâ delivers the same high-speed network connection you get through an Ethernet cable, but delivers it through your existing coaxial cable (the wire you use to receive cable TV) to any room in your home.
