Semiconductors and magnetism
I need well-explained answers on the questions in attached documents
What do you mean by the term Newton meter? Explain briefly?
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Briefly explain the procedure to define the Specific Gravity?
Siemens: S (after E.W. von Siemens, 1816-1892): The derived SI unit of an electrical conductance equivalent to the conductance of an element which has a resistance of 1 O [ohm]; this has units of O-1.
Beauty criterion (Dirac) - The idea that more aesthetically pleasing a theory is the superior it is. In nature this criterion does not stand up to the actual test -- whether or not forecasts of a given theory agree with observational tests -- however
Explain in short on which the gravitational force depends on?
Eddington limit (Sir A. Eddington): The hypothetical limit at which the photon pressure would surpass the gravitational attraction of a light-emitting body. That is, a body emanating radiation at bigger than the Eddington limit would
Explain Poisson equation and Poisson spot: Poisson equation (S.D. Poisson): The differential form of Gauss' law, that is, div E = rho, Pois
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
Briefly define or explain the cause of Brownian motion?
