1) When you rub one material, such as a balloon, againt another material, such as your hair, electrons are transfered from the atoms of the balloons to the atoms of you hair. what type of electricity is manifested in this experiment ? A. static electricity B. Themoelectricity C. Photo-electricity D. piezoelectricity 2) When we rub a balloon against a wall and creat that electrons transfer, we have a build-up of negative charge on the balloon and positive charge on the wall. this makes the baloons stick on the wall. This happens bacause opposite charge ____ A) Fell apart B) Get wet C) repel D) attract
