Which of these statements best explains why p waves arrive earlier than s waves at the seismic station?

a. s waves are generated after p waves arrive at the surface
b. s waves make longer lines on the seismogram than p waves
c. p waves are created first and s waves originate from p waves when they are reflected by solid rocks
d. p waves move straight through all medium and s waves move only through solids in a curvy motion

D. P waves move straight through all medium and S waves move only through solids in a curvy motion

Explanation:

The first kind of wave that is mentioned here is the P wave. This is also called the primary wave. This type of wave can move through solid rock and fluids. Because of this, this is the wave that arrives first at a seismic station. These are compressional waves. On the other hand, S waves are the second type of wave that you feel in an earthquake. These are slower and do not move through liquid mediums.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
