A wave of 0.3 m wave height and period 1.2 seconds is generated in a wave tank. The wave tank is 150 m. long, 3 m wide, and 4 m deep and filled with fresh water to a depth of 3 m. The density of water is 997 kg/m3. Required: a)Evaluate the wave celerity, length, group celerity, and energy in one wavelength. b)Determine the water particle velocity and pressure at a depth of 1 m below the still water level (SWL) and 0.2 m ahead of the wave crest. Use SI Units. c)Is the wave breaking

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
