Unformatted text preview: inflates a balloon by blowing into it. The end of the balloon is then tied. The balloon is rubbed with fur and develops an electrostatic charge. The balloon is placed against the ceiling and released. It remains “stuck” to the ceiling. The teacher then presents the following challenges to the students: • explain how the balloon received the electrostatic charge • explain why the balloon is attracted to the ceiling • provide a procedure that would determine if the charge on the balloon is positive or negative. Include a list of any additional equipment needed. • provide a procedure that could be used to determine if there is a relationship between the amount of rubbing and the amount of charge developed on an inflated balloon. Include a list of any additional equipment needed. Written Response—15% 1. Using concepts from Physics 30, provide a response to each of the teacher’s challenges. Marks will be awarded for the physics used to solve this problem and for the effective communication of your response. 24 25 Use the following information to answer the n...
