A sound wave enters a new medium where sound travels faster. How does this affect the frequency and wavelength of the sound?
OA The frequency increases and the wavelength decreases.
OB. The frequency decreases and the wavelength increases.
Ос. . The frequency stays the same and the wavelength increases.
OD. The frequency stays the same and the wavelength decreases.
O E. Neither the frequency nor the wavelength is affected.

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?
