Question

3. Your hair stands on when you remove a woollen cap​

Answer 1

Answer:

DUE TO ELECTRIC CHARGES IN THE woollen CAP

Explanation:

WHEN the cap is removed from the hairs they get rubbed and electric charges formed

Answer 2

Answer:

When you take off your wool hat, it rubs against your hair. Electrons move from your hair to the hat. Now each of the hairs has the same positive charge. Remember, things with the same charge repel each other. So the hairs try to get as far from each other as possible. The farthest they can get is by standing up and away from the others.
