WebThe speed of light in vaccum (c), depends on two fundamental constants, the permeability of free space (μ0) and permittivity of free space (ϵ0). The speed of light is given by c = 1 √μ0ϵ0. The units of ϵ0 are N−1C2 m−2. The units for μ0 are A kg−1 m−1C2 B kg m C−2 C kg−1 mC2 D kg−1 s−1C2 Solution The correct option is B kg m C−2 WebOct 12, 2016 · The fields are constantly changing during this time, and the changes in the field propagate outwards at the speed of light—fast, but finite. As the generator's cycle continues, the voltage decreases and the magnitude of the magnetic and electric fields also decreases. ...
