The epicenter of an earthquake is located in a sandy desert region. seismic waves move outward from the epicenter. a rocky region is located a few hundred miles from the desert. the particles of matter are more closely packed in rock than they are in sand. which statement correctly describes the change in seismic waves as they move from sand to rock?

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
