A narrow, monochromatic beam of light has a wavelength in a vacuum of 0.3.10^-12m A. determine the period, frequency of that light in a vacuum
B. calculate the speed and wavelength of that light as it travels through a transparent medium with a refractive index of 1.2

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

i think the answer is tomato juice? not entirely sure though
