Astudent is given 2 small, identical ice cubes and places the ice cubes on blocks of two unknown materials. the ice cube on block #1 melts in 37 seconds. the ice cube on block #2 melts in 24 seconds. based on this information, what should the student deduce about the unknown material of the blocks? question 2 options: block #1 is a better conductor because it caused the ice to melt more slowly than the ice on block #2 block #1 is a better insulator because it caused the ice to melt more rapidly than the ice on block #2 block #2 is a better conductor because it caused the ice to melt more rapidly than the ice on block #1 block #2 is a better insulator because it caused the ice to melt more rapidly than the ice on block #1

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?
