Hi @Wayneb! Welcome to OpenStudy! This question is not biology-related. You should post questions according to the disciplines they belong to. In this case, the question should be posted in the Physics' group [ http://openstudy.com/study#/groups/Physics ] Doing so would be following the code of conduct of OpenStudy :) Always make good use of OpenStudy :)
