curie's law
state and explain curie's law.
Brewster's law (D. Brewster) - The extent or level of the polarization of light reflected from a transparent surface is maximum whenever the reflected ray is at right angle to the refracted ray.
Coulomb: C (after C. de Coulomb, 1736-1806): The derived SI unit of an electric charge, stated as the quantity of charge shifted by a current of 1 A in a period of 1 s; it therefore has units of A s.
What do you mean by the term wave fronts? Explain in short.
Geometrized units: The system of units whereby certain basic constants (G, c, k, and h) are set to unison. This makes computations in certain theories, like general relativity, much simpler to deal with, as such constants appear often. Q : Explain Thomson experiment or Kelvin Thomson experiment: Kelvin effect (Sir W. Thomson [later Lord Kelvin]): Whenever an electric current flows via a conductor whose ends are maintained at various temperatures, heat is discharged at a rate just about proportional to the

The voltage v mV in a circuit is given by: v = 20 sin (200 Πt - 0.7854) where t is the time in seconds (a) State the amplitude, frequency, period and phase angle of v.(b) Determine the initial voltage.(c) Determin
What do you mean by the term density? Briefly explain it.
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
Name the instrument which is used to measure the volume? Explain in short?
Super fluidity: The phenomenon by which, at adequately low temperatures, a fluid can flow with zero (0) viscosity. These causes are related with the superconductivity.
