A migrating robin flies due north with a speed of 12 m/s relative to the air. The air moves due east with a speed of 6.1 m/s relative to the ground. What is the robin's speed relative to the ground?

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.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
