Question

Review | Constants Part A A water wave is a shallow-water wave if the water depth d is less than ~ 1/10. It is shown in hydrodynamics that the speed of a shallow-water wave is v= Vgd, so waves slow down as they move into shallower water. Ocean waves, with wavelengths of typically 110 m , are shallow-water waves when the water depth is less than 11 m. Consider a beach where the depth increases linearly with distance from the shore until reaching a depth of 4.4 m at a distance of 110 m. How long does it take a wave to move the last 110 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. μΑ ? Δt = Value Units Submit Request Answer
