12. Two boats are anchored 7.0 meters apart. They bob up and down, returning to the same up position every 10.0 seconds. The boats rise a vertical distance of 7.0 meters between their lowest and their
highest point. When one is up the other is down. There are never any wave crests between
the
boats. Determine the period, frequency, wavelength, amplitude and speed of the waves. PSYW
