WebA resonant coax-fed dipole antenna will have a low SWR and will radiate efficiently on the band for which it is resonant, but it will not work well on all bands. For example, if the tuning range of your tuner has a sufficient range, you will be able to load up any antenna with it, but it will not necessarily radiate a signal efficiently. WebFigure 1.4.4 – Torque on a Dipole. Multiplying the forces by the moment arms, and summing, we find that the magnitude of the torque on this dipole is: (1.4.2) τ = 2 [ q E d 2 sin θ] = q d E sin θ. The magnitude of the dipole moment appears in the equation, as does the strength of the electric field, and the sine of the angle between them.

A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules.
