Explain Pascals principle
Pascal's principle: The pressure exerted to an enclosed incompressible static fluid is transmitted undiminished to all portions of the fluid.
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
Eotvos law of capillarity (Baron L. von Eotvos; c. 1870): The surface tension gamma of a liquid is associated to its temperature T, the liquid's critical temperature, T*, and its density rho by: gamma ~=
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
Weiss constant: The characteristic constant dependent on the substance, employed in computing the susceptibility of the paramagnetic materials.
Transition temperature: The temperature (that is, dependant on the substance comprised) below that a superconducting material conducts electricity with zero resistance; therefore, the temperature above which a superconductor lose its superconductive p
Josephson effects (B.D. Josephson; 1962): Electrical effects examined whenever two superconducting materials are separated by a thin layer of the insulating substance.
Gaia hypothesis (J. Lovelock, 1969): The thought that the Earth as an entire must be regarded as a living organism and that biological procedures stabilize the atmosphere.
NUCLEAR PHYSICS (PHY555) HOMEWORK #1 1. Calculate the luminosity for a beam of protons of 1 µA colliding with a stationary liquid hydrogen target 30 cm long. Compare this to a typical colliding beam luminosity of ∼1034 cm-2
Cosmic censorship conjecture (R. Penrose, 1979): The conjecture, so far wholly undemonstrated in the context of general relativity, that all singularities (that is with the possible exception of the big bang singularity) are attended
Gauss' law for magnetic fields (K.F. Gauss): The magnetic flux via a closed surface is zero (0); no magnetic charges present; in its differential form, div B = 0
