I touched a negatively charged rod to a neutral object, and some negative charge was transferred to the object. This is an example of...
charging by induction
charging by polarization
charging by contact
not being smart - you should never do that
I bring a positively charged rod near a neutral metal sphere, which causes the negative charge within the sphere to move toward the rod, and the positive charge to move away from the rod. This is an example of...
charging by induction
charging by polarization
charging by contact
charging by friction
During a storm, convection currents cause a separation of charges in storm clouds, and then lightening strikes the ground due to...
the force of the convection currents
the attraction between negative and positive charges between the cloud and the ground
the negative and positive charges in the cloud repelling each other
the high potential energy in the cloud flowing to the low potential energy in the ground
