"Listen After sliding down a plastic slide on a dry summer day, 5.6 x 10 electrons are transferred from your body to the slide. What is the total magnitude of charge that was transferred? 1.39 x 10-4 C 3.50 x 1028 C 8.97 x 10-10 C 2.86 x 10-29 C Question 20 (1 point) ) Listen Why does lightning strike a lightning rod instead of the roof-top upon which it is mounted? 18 The lightning rod has a lower charge density on its surface compared to the flat surfaces of the roof-top 21 The lightning rod has the same polarity (positiveegative charge) as the bottom of the clouds just before the lightning strike 24 top Electric field lines are more concentrated around the lightning rod than the roof- All of the above
