Prof. Matt Dobbs Page 1/6 Physics 257 Asst 6 Physics 257: Assignment 6 Due in-class before 1:05pm Thursday November 1, 2007 Use MATLAB for this assignment. For plots, remember to label your axes correctly and use the “graphs” checklist on page 7 of the lab book. For each question, show all your steps including the raw commands you issue in MATLAB . Assignments handed in after 1:05pm but before the end of the day will lose 25% of the grade. The Mount Washington Experiment—Part II This part of the assignment is a continuation of the last assignment – be sure to read the intro from that assignment. 1. Assume the two points sit on an exponential decay curve You calculated N 0 and τ last assignment. Calculate the errors on N 0 and τ using error propagation.
