Question

With the scissor-over-comb technique, the angle of the comb will determine:

a) The length of the scissors' blades
b) The texture of the hair
c) The tension on the hair
d) The direction of the cut

Answer 1

The student will observe that the pieces of paper are attracted to the comb, which becomes statically charged by running it through their hair.

Step-by-step explanation:

The student, having run a comb through their hair several times, will observe that the pieces of paper are attracted to the comb. This phenomenon occurs because of the build-up of static electricity on the comb as a result of it being pulled through the hair, which creates an imbalance of electric charges. The comb becomes negatively charged, while the pieces of paper, being neutral, are attracted to the comb in an attempt to balance this charge difference.
