Dielectric Polarization
... Viewed from a microscopic perspective we know that the molecular polarizability is frequency dependent. Electronic polarizability is present in all molecules and has a response time that is rapid (> 1014 s-1). The high frequency response can follow the undulations of electromagnetic radiation in the ...

The physics of fusion power
... The likelihood of a fusion reaction is expressed in terms of a cross-section. A cross section has the dimension of an area, and one can roughly think of it as the size of the particles. A snooker ball, for instance, would have a cross section πr2 where r is the radius of the ball. For a fusion react ...

Relative Motion - Southern Polytechnic State University
... If a force P causes the particle to move along a path defined by r = f (q ), the normal force N exerted by the path on the particle is always perpendicular to the path’s tangent. The frictional force F always acts along the tangent in the opposite direction of motion. The directions of N and F can b ...
