2. Define Lightning conductor. How does it work?

device used to protect buildings from the damaging effect of the lightning.

A lightning conductor is used to save big buildings from the damage by lightning flashes.

Explanation:

The lightning conductor works on the principle of induction, such that when a charged cloud passes by the building, the conductor gets charge X opposite to that of the cloud through the process of induction.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
