What (e) If the answer to part (a) is \"yes,\" IS LIU Uni 3A tsunami is detected at 12:00 h on the edge of the continental shels a expected waming system. At what time can the tsunami be to reach in shoreline? 200 m 0.005 Kaming system sensor

Solution

Velocity of Tsunami waves = g x (h)^0.5 m/s ; where g is the gravitational acceleration ~ 10 m/s² and h is the depth of the warning system sensor where it is recorded. [ N.B. : for the formual see : https://en.wikipedia.org/wiki/Tsunami]

So, v = 10 x (200)^0.5 = 141.42 m/s

The distance from warning system sensor to the shoreline = 200/0.005 = 40000 m.

So, time to be taken by the tsunami wave to reach the shoreline after it is detected = 40000/141.42 =282.84 s i.e. 4 minutes and 43 seconds or time : 12:04:43.
