Question

Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticable, but upon reaching shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of 646 km and traveled a distance of 3630 km in 6.15 h. (a) What was the speed (in m/s) of the wave

Answer 1

Answer:

v =163.95 m/s

Explanation:

Given that,

The wavelength of wave, $\lambda=646\ km=646\times 10^3\ m$

Distance covered, $d=3630\ km=3630\times 10^3\ m$

We need to find the speed of the wave. We know that,

speed = distance/time

So,

$v=\dfrac{3630\times 10^3\ m}{22140\ s}\\\\=163.95\ m/s$

So, the speed of the wave is equal to 163.95 m/s.
