1. A sinusoidal wave with a height of 85 cm and a period of 5.935 sec is propagating in the ocean, at a depth of 11 meters. Determine the following: (a) The wave length. (6 points) (b) The velocity and the acceleration vectors (magnitude and direction) of the uid particles at points B and C, as shown in Figure 1, at t = 0, and at the time the wave trough passes over point B. (16 points) (c) The wave pressures at points B and C, at t = 0, and at the time the wave trough passes over point B. (10 points) (d) The minor and the major axes of the elliptical trajectories of the water particles at points B and C. (10 points) Drawing NOT to scale!
