Quantum chemistry mathematically describes the fundamental behavior of matter at the *molecular* scale
Quantum physics is a branch of physics providing a mathematical description of the dual particle-like and wave-like behavior and interaction of matter and energy at the *atomic or subatomic*...
the intensity of an electric field is determined by the charge of the emitting particle- which I will presume is constant for your stated moving particle- and the distance away from said particle.
Since the distance from a point is inevitable linked to the points point location, this is aptly...
