Fig. 28-6 shows two long, parallel current-carrying wires. the wires carry equal currents i1 = i2 = 20 a in the directions indicated and are located a distance d = 0.5 m apart. calculate the magnitude and direction of the magnetic field at a point located at an equal distance d from each wire.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Who was the first scientist to measure speed as distance over time?
