Can someone check my answer ? i think that it is a, but i am not sure.
a battery converts what type of energy into electrical energy?
a) mechanical
b) nuclear
c) solar
d) chemical

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

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.

less than one you can't create energy

i think its c if i'm wrong
