Damian felt a shock from electricity when he touched the metal knob on a door after walking across the carpet in his bedroom. Which statement correctly describes the type of electricity that caused the shock Damian received?
The shock is an example of static electricity which occurred because of the buildup of electrons that were discharged when he touched the door knob.
The shock is an example of current electricity which occurred because his hand intercepted the steady flow of electrons that are traveling through the door knob.

The pictures show four balloons that have gained negative charges after being rubbed against hair. The four balloons are placed next to a wall. Which balloon will most likely stick to the wall?
W because the negative charges in the balloon are attracted to the pattern of charges in the wall
X because the negative charges in the balloon are attracted to the mixture of charges in the wall
Y because the negative charges in the balloon are attracted to the positive charges in the wall
Z because the negative charges in the balloon are attracted to the negative charges of the wall
