Can someone please help me ASAP If light travels at 3.00 x10^8 m/s, how long will it take light from the sun to reach a planet that is 6.45 light years away? How far will the light have traveled in meters? (Light year- distance travelled by light in one year. Use a value of exactly 365 days for a year.)

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?
