Science Buddies: "Ask an Expert"

hi

howtodo,

Welcome to science buddies. It seems like the questions you posted are a copy of a homework questionnair of some kind. If you have a specific question to clarify one or more aspects of these topics, we'd be more than happy to help where possible. However, the experts at science buddies try not to complete homework assignments the student should be completing. We'd like the opportunity to help overall understanding, so if there is something you dont understand about the research required to answer these questions, please repost those.
