the balloon is rubbed on the sweater. negative charges move from the sweater to the balloon. think about the charges each object has after the objects are rubbed together. which model shows the charges after rubbing?
Answer
# Explanation:
## Step1: Understand charge - transfer
When negative charges move from the sweater to the balloon, the sweater loses negative charges and becomes positively - charged. The balloon gains negative charges and becomes negatively - charged.
## Step2: Analyze the models
In the first model, the sweater has positive charges and the balloon has negative charges which is consistent with the charge - transfer described. In the second model, both the sweater and the balloon have positive charges which is incorrect as the balloon should gain negative charges.
