If a p-wave arrives at 2:10:00 and the s-wave arrives at 2:15:20, how many kilometers from the epicenter is a location?

2.67 x 10⁷km

Explanation:

Given parameters:

    Time of arrival of p-waves  = 2: 10: 00

    Time of arrival of s-waves = 2: 15: 20

Unknown:

Distance of wave from epicenter  = ?

Solution:

 To find the distance of the wave from the epicenter;

     Distance = 3 x 10⁸ x time interval

Time interval = Time of arrival of p-waves  - Time of arrival of s-waves

                       =  2: 10: 00 - 2: 15: 20

                       = 5min 20s

                       = 320s

Now, we need to convert the time to hrs;

        3600s  = 1hr

         320s  =  = hr

So,

   Distance =  3 x 10⁸  x   = 2.67 x 10⁷km

the answer is the first option

explanation:

just googled it m8. not that hard

lol

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
