answer the question plz

(b) It is proposed to install a wave energy converter at a site where the water depth is 45m and the seawater density is 1025kg/m3. At the proposed site a pressure transducer is located 7m below the still water level (SWL). Figure 1 shows pressure measurements obtained from the transducer. The wave period is 10s and the maximum pressure is 80.77kN/m2. Determine the following: 1. The length and height of the waves at the site. [4 marks] 2. When in the wave cycle the pressure at a point 7m below SWL is equal to 67.18kN/m2. If the pressure is equal to 67.18kN/m2 more than once in the wave cycle, you are required to determine time for each occurrence. [6 marks] 3. The pressure at a point 7m below the SWL under the wave trough, 0 -crossing between crest and trough, 0-crossing between trough and crest
