When yоu drive yоur cаr, аir flоws аround it and the rubber tires have a large frictional force to help you grip the road as you drive. You may have noticed that if you get right out of your car after driving it, you get a slight shock when you touch any part connected to the metallic frame. For this reason it is always recommended that you ground the car before putting the metal gas pump nozzle into your tank opening. With as much detail as you can, using the vocabulary from chapter 5, please explain why you get shocked, and why it does not dissipate (fade away) immediately. Please comment on the moment before the shock occurs and what must happen. For an extra bonus point, can you where the charge comes from?
