A quantity named for one of these objects can be expressed as a sum over copies of the L equals one solid harmonic.
A quantity named for one of these objects can be expressed as a sum over copies of the L equals one solid harmonic. A time-varying one of these objects emits radiative power proportional to the fourth power of its frequency. The torque on one of them is perpendicular to an applied electric field, and the strength of one of them is equal to a volume integral of charge density times position. This object gives its name to the one over (*) r-squared term in a power series for electric potential, and its electric field falls off as one over r cubed. For 10 points, name these objects whose "moments" are measured in debyes, charge configurations consisting of two equal and opposite charges separated by a small distance.
