Hello @pjmavp, welcome to OpenStudy. Nice to see a new user on the site. However, a much more appropriate place for this question would be in the Physics section. You can access it by clicking the "Find More Subjects" link up at the top. It will open a menu where you can scroll down to physics. You are much more likely to receive the help you desire there!
