Aclosely wound rectangular coil of 80 turns has dimensions 25.0 cm by 40.0 cm. the plane of the coil is rotated from a position in which it makes an angle of 37.0 degrees with a magnetic field of 1.10 t to a position perpendicular to the field. the rotation takes 0.0600 s. what is the average emf e induced in the coil

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
