Question

) One can estimate the speed of a tsunami wave by the formula v = (y g)½. Determine the value of v if y = 5400 meter (note: g = 9.80 m/s2). a.) 110 m/s b.) 230 m/s c.) 390 m/s d.) 67 m/s Answer __________ 2.) Convert v = 230 m/s to units of kilometer/hour. a.) 12 km/hr b.) 106 km/hr c.) 828 km/hr d.) 524 km/hr Answer __________ 3.) If vtsunami = (y g)½ , then the vtsunami values can be summarized as follows: a.) vdeep water > vshallow water b.) vdeep water = vshallow water c.) vdeep water vshallow water d.) none of the above is true Answer __________ 4.) An earthquake occurs on the ocean floor 20 kilometers west of the coast of Peru in South America and the resulting sudden earth movement produces a tsunami wave. Estimate the time required for the wave to propagate to Hawaii. (Similar earthquakes are a matter of historical record within the past twenty years.) a.) 4 hours b.) 0.4 hours c.) 12 hours d.) 2 days Answer __________ 5.) An earthquake occurs 20 kilometers east of the main islands of Japan and the resulting sudden earth movement produces a tsunami wave. Estimate the time required for the wave to propagate west to the main islands of Japan. (Again, this is a matter of historical record, quite checkable online.) a.) 4 hours b.) 0.4 hours c.) 12 hours d.) 2 days
