Question

a balloon is rubbed against a wall. the picture on the left shows the balloon and the wall before rubbing. the picture on the right shows the balloon and the wall after rubbing. what happened when the balloon was rubbed against the wall? \\(\bigcirc\\) a. electrons were transferred from the balloon to the wall. \\(\bigcirc\\) b. protons were transferred from the wall to the balloon. \\(\bigcirc\\) c. protons were transferred from the balloon to the wall. \\(\bigcirc\\) d. electrons were transferred from the wall to the balloon.

Explanation:

When a balloon is rubbed against a wall, static electricity is involved. Protons are in the nucleus and do not transfer during rubbing (ruling out B and C). After rubbing, the balloon and wall attract (implied by the diagrams). For the balloon to become charged (e.g., negative) and the wall positive, electrons (negative charge) must transfer from the wall to the balloon, matching option D.

Answer:

D. Electrons were transferred from the wall to the balloon.
