Define Permittivity of free space or electric constant
Permittivity of free space: electric constant; epsilon_0: The ratio of the electric displacement to the intensity of the electric field generating it in vacuum. It is equivalent to 8.854 x 10-12 F/m.
Illustrate the steps to the scientific notation? Briefly illustrate the steps.
Stern-Gerlach experiment (O. Stern, W. Gerlach; 1922): The experiment which explains the features of spin (that is intrinsic angular momentum) as a different entity apart from the orbital angular momentum.
Explain Correspondence limit or Correspondence principle? Correspondence limit (N. Bohr): The limit at which a more common theory decreases to a more specialized theory when the situations that the
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
Ergosphere: The area around a rotating black hole, among the event horizon and the static limit, where the rotational energy can be removed from the black hole.
Is it possible to obtain the electron (or come out) from the nucleus?
Tardon: A particle that has a positive real mass and travels at a speed very less than c in all inertial frames.
Young's experiment: double-slit experiment (T. Young; 1801): A well-known experiment that exhibits the wave nature of light (and certainly of other particles). The light is passed from a small source into an opaque screen with the two thin slits. The
Equivalence principle: The fundamental postulate of Sir Einstein’s general theory of relativity that posits that acceleration is basically indistinguishable from the gravitational field. In another words, when you are in an elevator that is utte
