You are the navigator of a ship at sea. You receive radio signals from two transmitters A and B, which are 90.0 km apart, one due south of the other. The direction finder shows you that transmitter A is at a heading of 32° south of east from the ship, while transmitter B is due east. Calculate the distance between your ship and transmitter B.

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?
