X/10. It is √gd, so A water wave is a shallow-water wave if the water depth d is less than shown in hydrodynamics that the speed of a shallow-water wave is v = waves slow down as they move into shallower water. Ocean waves, with wavelengths of typically 100 m, are shallow-water waves when the water depth is less than 10 m. Consider a beach where the depth increases linearly with distance from the shore until reaching a depth of 5.4 m at a distance of 100 m. Part A How long does it take a wave to move the last 100 m to the shore? Assume that the waves are so small that they don't break before reaching the shore. Express your answer to two significant figures and include the appropriate units. At = Value Units ?
