A spherical cavity is excised from the inside of the sphere. The cavity has radius a4 and is centered at position h⃗ , where |h⃗ |<34a, so that the entire cavity is contained within the larger sphere. Find the electric field inside the cavity.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

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.

i would say the answer is food.

hope this !
