Question

if an earthquake wave having a wavelength of 9.82 km causes the ground to vibrate 13.0 times each minute, what is the speed of the wave?

Answer 1

The speed of the earthquake wave is 2.13 km/s.

Step-by-step explanation:

To find the speed of the earthquake wave, we can use the formula:

speed = frequency * wavelength

In this case, the frequency is 13.0 times per minute, which we can convert to Hz by dividing by 60.0 (since there are 60 seconds in a minute). So the frequency is 13.0 / 60.0 = 0.217 Hz. The wavelength is given as 9.82 km.

Now we can plug these values into the formula:

speed = 0.217 Hz * 9.82 km = 2.13 km/s

Therefore, the speed of the earthquake wave is 2.13 km/s.
