Marianne designs an experiment involving electrically charged objects. She wants to know which objects will be attracted to a negatively charged balloon. Identify the test variable, the outcome variable, and the control variable for this experiment.
Answers
Answer:
When one object is rubbed against the another, static electricity can be created because the rubbing creates a negative charge, carried by electrons
Explanation:
When one object is rubbed against the another, static electricity can be created because the rubbing creates a negative charge, carried by electrons
Explanation:
When we rub a balloon on our head, it causes opposite static charges both on hair and balloon. When the part of the balloon has a negative charge. Balloons, the electrical insulators, resist electric charges flowing through them. So only a part of the balloon has negative charge (where the wool is rubbed) and other places remain neutral.
• When a balloon is rubbed to wall, it will be attracted to the wall. The charge is not immediately discharged as the wall is an electrical insulator.
• When we rub the balloon against metal, the extra electrons in the balloon quickly leave the balloon and move into the metal so the balloon is no longer attracted and does not adhere.
