Question 1. A wave of period 10s approaching the shore has a height of 1m in deep water. Calculate (use ?=1.03×103 kg m-3)
(a) The wave speed and group speed in deep water =
(b) The wave steepness in deep water =
(c) The wave power per metre length of crest in deep water =
(d) The wave power per metre length of crest in water 2.5 m deep =
Question 2. Ice particles and super cooled water droplets exist in the same cloud at a temperature if T = 260 K. The water vapor pressure in the cloud is P h2o = 2.50mb. Develop an argument that shows the liquid droplets will tend to evaporate and the ice particles will tend to grow.
