2. (5 points) Solar radiation strikes Earth's atmosphere each day. These collisions knock electrons off of atoms and create very many ions. Rain carries the electrons to the ground so that, to a good approximation, Earth's surface can be thought of as a uniform shell of negative charge-Q and the atmosphere can be thought of as a concentric shell of positive charge +Q. What is the magnitude of the resulting electric field (due to this arrangement of charges) that an...

Question: Write at least two paragraphs discussing things that you learned from the background portion of this lab. Be sure to include your interpretation of why nuclear fusion does not occur naturally on the Earth as well as why we do not yet have the technology to replicate the process. lab/Background Information: Nuclear fusion is a very important physical process that governs how the Universe evolves. It occurs naturally in stars, but has not been observed to occur naturally anywhere...
