What happens when you rub a plastic object with a cloth?

• Electrons move from the plastic to the cloth.

• The plastic becomes negatively charged.

• The cloth becomes positively charged.

• Electrons move from the cloth to the plastic.

Why does a person's hair stand on end when touching a Van de Graaff generator?

• The hair becomes positively charged and repels each other.

• The hair becomes negatively charged and attracts each other.

• The hair becomes neutral and falls flat.

What is the role of the metal dome in a Van de Graaff generator?

• It neutralizes the charge.

• It stores positive charge.

• It stores negative charge.

• It prevents the generator from working.

How can static electricity cause a spark during aircraft refueling?

• By building up a positive charge on the fuel.

• By building up a negative charge on the aircraft.

• By building up a neutral charge on the refueling truck.

• By building up an electrostatic charge in the refueling pipe.

What is a common method to prevent sparks during refueling?

• Using non-conductive materials.

• Grounding both the refueling truck and the airplane.

• Increasing the speed of fuel flow.

• Using a plastic refueling pipe.
