The relative motion of the Earth with respect to the rest of the universe produces an anisotropy of this type in the CMBR.
The relative motion of the Earth with respect to the rest of the universe produces an anisotropy of this type in the CMBR. The Laporte selection rule only applies to electronic transitions of this type. The power of the radiation emitted by an oscillating one of these objects is proportional to the 4th power of the oscillation frequency. Hertz invented a simple antenna described by this word. The electric field created by one of these objects falls off with the (*) inverse-cubed power of distance. The torque on one of these objects in an external field is given by the cross-product of a quantity characterizing them with the field. The Coulomb-meter and the Debye are units of their namesake "moment." For 10 points, name this configuration of a positive and a negative charge separated by a short distance.
