An earthquake emits both s-waves and p-waves which travel at different speeds through the earth. a p-wave travels at 9000 m/s and an s-wave travels at 5000 m/s. if p-waves are received at a seismic station 2.00 minute before an s wave arrives, how far away is the earthquake center?

the distance is 1350 Km

Explanation:

To solve this problem we will use the formulas of contant velocity motion:

Because the waves have to travel the same distance we can set the following equallity:

We know that the s waves arrive 2 minutes later, that is 120 seconds:

Rearranging the last equation we have :

As we said before they have to travel the same distance, so:

what type of charge does it have? negative

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.
