Sara walks across a rug on the floor when the doorbell rings. She opens a door and gets a shock. What type of charge will Sara have after the shock? Explain how you know in 1-2 sentences.(2 points)
Sara will have a positive charge after the shock. This is because when she walks on the rug, the friction causes her to accumulate extra electrons, giving her a negative charge. When she touches the doorknob, the excess electrons flow from her to the doorknob, leaving her with a positive charge.
can you do it more simpler
Sara will have a positive charge after the shock because during the friction on the rug, electrons move from the rug to Sara, giving her extra electrons. When she touches the doorknob, the extra electrons transfer from Sara to the doorknob, leaving her with a positive charge.
can you be more simple
Sara will have a positive charge after the shock because when she walks on the rug, she collects extra electrons. These electrons transfer to the doorknob when she touches it, leaving her with a positive charge.
