Final answer:
When a comb is run through hair and becomes statically charged, it will attract small pieces of paper due to the creation of a static electric field that polarizes the neutral paper pieces.
Step-by-step explanation:
The subject in question relates to static electricity, which is a concept in physics. When a comb is run through the hair several times, it often becomes electrically charged due to the transfer of electrons, a process known as triboelectric charging. This causes the comb to exhibit static electric properties.
Upon bringing the charged comb near small pieces of paper, the student will observe that the pieces of paper are attracted to the comb. This attraction occurs because the paper pieces, being neutral, are polarized by the charged comb, causing the side of the paper pieces closer to the comb to become slightly more positively charged, thus resulting in an attraction due to the comb's negative charge.
