Joe's boat leaves the harbor and heads straight for treasure island, which is 37 degrees north of west. joe travels 23 km to reach the island. moe leaves a little while later and first heads north to try and get a glimpse of some dolphins (that had earlier been sighted by her friends). moe travels 11 km due north and reaches nomans island. at this point she is disappointed at having seen no dolphins and heads straight for treasure island. what is the distance traveled by moe from nomans island to treasure island?

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?
