Question

select all the correct answers. when people use plastic combs on their hair, the combs become negatively charged. which statements about this situation are true? the comb loses electrons. the comb gains electrons. the hair loses electrons. the hair gains protons. the hair loses protons.

Explanation:

When two materials are rubbed together, electrons can be transferred. A negatively - charged object has gained electrons. In this case, the comb becomes negatively charged, so it gains electrons. Since electrons are transferred from one object to another, the hair loses electrons. Protons are in the nucleus and are not transferred during such triboelectric charging.

Answer:

• The comb gains electrons.
• The hair loses electrons.
