Ling built a circuit with three light bulbs. She observed that all three light bulbs glowed. then she removed one light bulb, and the others stopped glowing. She claimed that the other light bulbs had burned out. How could Ling gather evidence to support her claim?

State one advantage and one disadvantage of using a plane mirrior as a driving mirrior

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

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?
