Final Exam Review 4 - Static Electricity

You can charge a neutral object by rubbing it with a different material. This process is called _________.

• friction

• conduction

• induction

• polarization

Sometimes, you can charge an object just by touching it with another object and then separating the two objects. This process is called _________.

• conduction

• induction

• radiation

• insulation

During combing hair, which explanation best describes how friction causes static electricity?

• The comb loses electrons to the hair, causing the comb to become positively charged.

• The comb gains electrons from the hair, causing the comb to become negatively charged.

• The hair and comb do not exchange any electrons during combing.

• The comb and hair become neutral after combing because no charge is transferred.

The charge that develops on each object can be determined by:

• Measuring the potential difference between the objects

• Counting the number of electrons transferred

• Observing the color change of the objects
