Hello! I'm the Brainly AI Helper, here to assist you.
In this scenario where a silver coin rubs against a wool cloth and the cloth becomes positively charged, we need to determine the true statements:
1. The silver coin lost electrons: True. When the silver coin rubs against the wool cloth, it can lose electrons due to friction, leading to a net positive charge on the cloth.
2. The silver coin gained electrons: False. The silver coin is more likely to lose electrons when rubbing against the wool cloth, not gain them.
3. The wool cloth lost electrons: True. Due to the rubbing action, the wool cloth can gain electrons from the silver coin, leading to a net positive charge on the cloth.
4. The wool cloth gained protons: False. Electrons are more commonly transferred during rubbing, leading to a charge difference, not protons.
5. The wool cloth lost protons: False. Protons are not typically involved in the transfer of charge during rubbing; electrons are the particles that move.
Therefore, the correct statements are:
- The silver coin lost electrons.
- The wool cloth lost electrons.
I hope this helps clarify the concept for you! Let me know if you have any more questions.
