Answers
Answer:
1=During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod
2=.Safety precautions indoors
Avoid water during a thunderstorm. Lightning can travel through plumbing.
Avoid electronic equipment of all types. Lightning can travel through electrical systems and radio and television reception systems.
Avoid corded phones. ...
Avoid concrete floors and walls.
3=Hence, an electrical discharge occurs within the clouds or between the clouds and the ground when sufficient negative and positive charge gathers inside the cloud and when the electric field becomes sufficiently strong. ... This produces bolt.
