Physics 10 Midterm exam 1 Part A – Essay Questions October 3, 2003 Last name____________________ First name___________________SID___________ Essay questions (20 pts): pick one and only one to answer. Write a page or two (or whatever is appropriate) on this sheet. Cover the important points in a clear and concise manner – as if you have only a few minutes to tell the President, Mayor, or your roommate, what that person needs to know. Clear, effective writing is important. 1. Describe the physics behind satellites that orbit the earth. Be sure to relate LEO, GEO, and the moon in your discussion, and note any practical uses for each kind of artificial satellite. 2. Suppose it is announced that a laboratory in downtown Berkeley accidentally released some radioactive gases into the environment, and this would cause an exposure to people who worked nearby of about 1 millirem (0.001 rem) over the next year for each person who works there. Assume 1000 people work there. The mayor of Berkeley asks you to speak to the public to alert them to the risks they face. What would you say? Give numbers when appropriate.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
