Compute the self-inductance of a toroid of square cross section if it is wound with 200 turns. the inner and the outer radii of the toroid are 20 cm and 25 cm, respectively. the relative permeability of the mag netic material is 500. if the current in the coil varies sinusoidally as 2 sin 314r a, determine the induced emf in the coil

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface
