Please answer all the questions, and, if possible, please post links to diagrams (when a diagram is required). Thank you very much in advance for your help.
P.S. In the case of answerers being interested as to the nature of my question, I have to study Physics at home, through the use of various books, with no teacher to help me. These are questions from one of the books (with no answers included), with which I have been struggling. Therefore, I would appreciate as detailed an answer as possible to them.
