- 1) If you want to know the speed of a long-wavelength wave (e.g. tsunami or tide), you can use the shallow-water wave velocity equation v=gd where g is acceleration due to gravity (~10 m/s2), d is water depth (in meters), and v = speed (in meters per second). a) Calculate the speed of a tsunami (in meters per second), assuming an average ocean depth of 4000m. b) Convert the speed of a tsunami from meters per second to meters per hour (note that 1 hr = 3600 seconds). c) Convert the speed of a tsunami from meters per hour to miles per hour (note that 1 mile = 1600m).1. Storms in the South Pacific can create waves that travel all the way to the California coast, 12000 km away. How long does it take them to travel this distance if they travel at 21 m/s? t D V hrsAn observer measured an interval of 10 s between seeing a lightning flash and hearing thunder.
