144. If your car gets struck by lightning in a thunderstorm, will you be safe. Why? Yes

145. Answer: You will be safe because your cars metal chassis acts like a Faraday Cage.

146. Answer: You will be safe because your cars metal chassis acts like a Faraday Cage. The charged particles travel around the outside of the car and into the ground.

152. A Faraday cage is a metallic enclosure that prevents the entry or escape of an electromagnetic field.
