Conductors are objects which permits the free flow of electrons(electric current). Examples of conductors include metals such as silver, copper, iron etc.

Insulators are objects which doesn’t permit the free flow of electrons(electric current).Examples include non metals such as wood, plastic, wool etc.

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.
