A student has rubbed a balloon on his hair. He holds it 15 centimeters away from the wall and it falls to the floor. He holds it 5 centimeters from the wall and it is attracted to the wall and “sticks” to the wall (as shown below). Which of the following best describes what has happened?
The electrons from his hair transferred to the balloon, causing it to be negatively charged. The positively induced wall attracted the balloon at a small distance.
The electrons from his hair repelled the protons, causing it to be positively charged. The neutral wall attracted the balloon at a small distance.
The protons from his hair transferred to the balloon, causing it to be positively charged. The negatively induced wall attracted the balloon at a small distance.
The protons from his hair repelled the electrons, causing it to be negatively charged. The neutral wall attracted the balloon at a small distance.

Static electricity is particularly fun in the winter when wool hats are worn more regularly. Which of the following correctly explains the static electricity occurring after wearing a wool hat?
The protons from hair are transferred to the wool cap, making the hair attracted to the air around it once the hat is removed
The electrons from hair are transferred to the wool cap, making the hair positively charged, Therefore, the hairs repel each other and move as far away from each other as possible.
The wool cap accumulates the protons and leaves the hair electrically negative.
The wool cap transfers its electrons to the hair making the hair electrically positive.
