Please help with physics homework!!!! Ive tried and tried and tried show me up! IT’s dealing with waves.?
Please help me solve this problem i hope you can help it would be very much appreciated. VERY MUCH!
Earthquakes produce two kinds of seismic
waves: he longitudinal primary waves (called
P waves) and the transverse secondary waves
(called S waves). Both S waves and P waves
travel through Earth’s crust and mantle, but
at different speeds; the P waves are always
faster than the S waves, but their exact speeds
depend on depth and location. For the pur-
pose of this exercise, we assume the P wave’s
speed to be 8220 m/s while the S waves travel
at a slower speed of 4820 m/s.
If a seismic station detects a P wave and
then 63.5 s later detects an S wave, how far
away is the earthquake center?
Answer in units of km.
8220-4820=3400
3400*63.5=215900
215900 m=215.9 km
