Sonia was experimenting with electric charges. she tied two inflated balloons together, held them next to each other, and rubbed both with a piece of wool. what did sonia observe, and why?

Sonia will experience repulsion in two balloons

Explanation:

Here when we rub the balloon with the woolen cloth then due to friction between the cloth and balloon electrons from balloon will transfer to woolen cloth.

Due to transfer of electron the balloon will get positive charge which is given by

so here since both balloons are rubbed against woolen cloth so both balloon will get some positive charge

now we know by the property of charge that two similar charges will always repel each other so here two balloons will repel each other after they rubbed against woolen cloth.
