Jake hangs two balloons from a desk so that they are close together but not touching. Jake rubs one balloon with a wool cloth. He does nothing to the other balloon. What happens when he lets go of the balloons?

Cecilia is combing her hair. What will most likely happen when she holds the comb near a small, uncharged object

Wanda rubs a balloon against her wool sweater, and the balloon sticks to the sweater. Then she observes the balloon sticking to a wall. Why is this a scientific investigation but not an experiment?

Immanuel Ibarra · Answer 1

The objects that are rubbed together will create charges among themselves due to friction.

(1) The balloon rubbed with a wool cloth will be charged.

(2) If she comb near a small, uncharged object nothing will change.

(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
