There are 100 turns in a coil of wire. When coil is displaced from one point to another in 0.01 s between the poles of two magnets a change of magnetic flux of 30×10-5 Wb

takes place. What is the induced electromotive force in the coil?

What is the radius of the circular path ofa charged particle in a magnetic field?

A150 w lamp emits light of wavelength 590 nm uniformly in all directions. what is the photon flux (photons per unit area per unit time) on a small screen at a distance 2.3 m from the lamp? assume the photons are uniformly distributed over the surface of a sphere of radius 2.3 m.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
