H a m m e r h e a d shark A hammerhead shark (Figure P18.51) has a 0.90-m-wide head. The shark swims north at 1.8 m/s. Earth’s field at this location is 5.0 x 10^-5 T and points 30° below the direction of the shark’s travel. Determine the potential difference between the two sides of the shark’s head.
