Q. What is an electric dipole? Define: the dipole moment.
Two equal as well as opposite charges separated by a very small distance constitute an electric dipole. Instances ammonia, water, carbon-dioxide as well as chloroform molecules the dipole moment is the product of the magnitude of the one of the charges and the distance between them. ∴ Electric dipole moment p = q2d or 2qd.
It is a vector quantity as well as acts from -q to +q the unit of dipole moment is C m.

Magnetism - Basic concepts: 1. Pole strength: The ability of a pole of a magnet to attract or repel another magnetic pole is called its pole strength. Units : A-m 2.
left-hand rule: It is the opposite-chirality version of the right-hand rule.
The loudness of sound depends on: Amplitude of vibration. Area of vibrating body. Distance from the sounding body. Density of the medium.
Why does heated air expand? Temperature is often explained as the average thermal energy of the substance at hand. Therefore the hotter a substance is the more thermal energy i
