For the diagram below, a siren is going off in the distance to the left. The diagram shows the diffraction of the siren's sound wave around the wall. If you were behind the wall (position labeled "X") what would you hear? wall spurd waves for source to the left, moving to the right. X O A. You would hear the siren, but the pitch would sound higher. O B. You would hear the siren and think it was located at the opening in the wall. O C. You would not hear anything because there is no sound wave at that position. O D. You would not hear anything, because the wall would block the sound of the siren.β

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?
