At the instant when the current in an inductor is increasing at a rate of 6.35×10−2 a/s , the magnitude of the self-induced emf is 1.65×10−2 v . you may want to review (pages 994 - 997) . for related problemsolving tips and strategies, you may want to view a video tutor solution of calculating self-inductance.

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

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
