WebbView questions only. See Page 1. 20.A neutral plastic strip is rubbed with cotton and acquires a positive charge. Which of the following statements are true of the positively‐charged strip?a. It lost some electrons to the cotton during the charging process. b. It lost all of its electrons to the cotton during the charging process. WebbThe rubbing encourages PVC molecules to snatch electrons from the wool, so it becomes negatively charged. The wool loses some of its electrons and therefore becomes slightly … hannah moitozo

WebbWhen a piece of amber is rubbed with a piece of silk, the amber gains more electrons, giving it a net negative charge. At the same time, the silk, having lost electrons, becomes positively charged. (credit: Sebakoamber, Wikimedia Commons) What makes plastic wrap cling? Static electricity. WebbPlastic foam or Styrofoam TM is an insulator; it will hold its charge until it is discharged by current leaking into the air or along a moisture film on its surface. When you place the pie pan on the foam plate, the electrons on the foam repel the electrons on the pan. WebbFigure 1. This power adapter uses metal wires and connectors to conduct electricity from the wall socket to a laptop computer. The conducting wires allow electrons to move freely through the cables, which are shielded by rubber and plastic. These materials act as insulators that don’t allow electric charge to escape outward. hannah martin makeup lessons
