Answer: Question 9 Not yet answered Marked out of 1 Not flaggedFlag question Question text Miss Chiff, the 7th grade science teacher, greets her students in an unusal manner. She stands at the door of her classroom, scuffing her feet back and forth on the carpet. As she does so, electrons move from the carpet to her shoes to her body. Miss Chiff is now charged with a ____ type of charge. Select one: a. neutral b. positive c. unbalanced d. negative Question 10 Not yet answered Marked out of 1 Not flaggedFlag question Question text When students enter the classroom, Miss Chiff reaches out and touches her students on the nose as they enter the classroom. As she does, some electrons leave Miss Chiff and move onto her students. Miss Chiff is now ___ negatively charged than before the contact with the student. The student is now charged with a ____ type of charge. Select one: a. more, negative b. less, positive c. more, positive d. less, negative Question 11 Not yet answered Marked out of 1 Not flaggedFlag question Question text In a lab report during the Static Electricity unit, Aaron suggests that a sample of wool became postively charged by gaining protons from the rubber balloon that is rubbed. Explain what is wrong with Aaron's statement. Select one: a. Protons only move from the nucleus when they are connected to an neutron and cannot bond with other objects. b. Protons only move from the nucleus when they are connected to an electron so the cahrge is always neutral. c. Protons are bound together in the nucleus. They can't move from atom to atom. d. Protons are bound together in the nucleus. They can only move outside the nucleus when the temperature rises.
