PHYSICS 7A Study Guide - Midterm Guide: David Catcheside, Angular Velocity, Lagrangian Point
Document Summary
You will be given 120 minutes to work this exam. No books are allowed, but you may use a double-sided, handwritten formula sheet no larger than an 8 by 11 sheet of paper. No calculators or other electronics are allowed (wouldn"t help much anyhow ). Your description of the physics involved in a problem is worth significantly more than the final answer by itself. Show all work, be careful with signs, and take particular care to explain what you are doing. Please express your answers using the symbols provided in the problem descriptions or define any new symbols you use, tell us why you"re writing any new equations, and clearly label any drawings that you make. Write your answers in a blue book (or green book), and do not use any extra scratch paper. Good luck: (25 points) two stars and a planet. Consider a pair of stars that form a binary solar system.
