According to clocks on the ground (system s), streetlights a and b (situated 4 km apart) were both turned on at precisely 8: 00p. m. which one went on first according to an observer on a train (system s') which moves from a to b at 3/5 times the speed of light? how much later (in seconds) did the other light go on?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
