Answer: The tissue paper will stick to the balloon because it is positively charged.
Explanation:
When the balloon is rubbed with a wool cloth, then the balloon will have more negative charges than the positive charges.
There is no charge on the tissue paper. It is neutral. When it approaches to the balloon then the additional negative charge on the balloon will attract the positive charge in the tissue paper.
The tissue paper will stick to the balloon because it is positively charged.
When wool is rubbed with a balloon, the wool is left with a positive charge as electrons have travelled from the wool to the balloon which means the balloon now has a negative charge.
Now that the balloon has a negative charge, you need to know: The tissue paper originally contains electrons and protons The fact that the balloon has a negative charge, it will ATTRACT protons because protons are POSITIVE and electrons are NEGATIVE. So once they are attracted, they will move closer to one another.
You draw 3 circles around the stations with the size of the circle equal to the distance from the earthquake. Then you simply find where the edge circles all overlap.
