Machine Answer Sheet: Using a pencil, fill in Last Name, First Name, & Middle Initial, plus your 10-digit Purdue University ID number. Enter Instructor (Ritchie or Csathy), Course (PHYS 172), Date (12/15/09). Leave “Section” blank. You must include your Signature. The 14 machine-graded problems are worth 14 points each except for the first one which is worth 18 points (200 points total). If your answer is slightly different from any of the choices due to round-off errors, etc., then select the closest choice.
