When combing your hair you scuff electrons

I’m studying and need help with a Physics question to help me learn.

Need help with some text questions from the exercise end of chapter from the Conceptual Physics text 11e by Hewitt• Ch. 22: Exercises 8 & 38 8. When combing your hair, you scuff electrons from your hair into your comb. Is your hair then positively or negatively charged? How about the comb? 38. If you rub an inflated balloon against your hair and place it against a door, by what mechanism does it stick? Explain. • Ch. 23: Exercises 1 & 26 1. What two things can be done to increase the amount of flow in a water pipe? Similarly, what two things can be done to increase the current in an electrical circuit? 26. Are automobile lights wired in parallel or in series? What is your evidence? • Ch. 24: Exercises 3 & 22 3. All atoms have moving electric charges. Why, then, aren’t all materials magnetic? 22. Your friend says that, when a compass is taken across the equator, it turns around and points in the opposite direction. Your other friend says that this is not true, that people in the Southern Hemisphere use the south magnetic pole of the compass to point toward the nearest pole. What do you say? • Ch. 25: Exercises 2 & 31 2. A common pick up for an electric guitar consists of a coil of wire around a small permanent magnet. Why will this type of pick up fail with nylon strings? 31. Why is it important that the core of a transformer pass through both coils? • Ch. 32: Exercises 6 & 28 6. Why does classical physics predict that atoms should collapse? 28. When and where do Newton’s laws of motion and quantum mechanics overlap? • Ch. 33: Exercises 37 & 47 37. A friend suggests that nuclei are composed of equal numbers of protons and electrons, and not neutrons. What evidence can you cite to show that your friend is mistaken? 47. Why is carbon dating ineffective in finding the ages of dinosaur bones? • Ch. 34: Exercises 1 & 14 1. Do today’s Nuclear power plants use fission, fusion, or both? 14. The water that passes through the reactor core of a water moderated fission reactor does not pass into the turbine. Instead, heat is transferred to a separate water cycle that is entirely outside the reactor. Why is this done? ...
