Aparallel-plate air-filled capacitor having area 40 cm² and plate spacing 1.0 mm is charged to a potential difference of 600 v. (a) find the capacitance. (b) find the magnitude of the charge on each plate. (c) calculate the total stored energy. (d) determine the magnitude of the electric field between the plates (ignore fringing! fields at the edges).

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?
