Part 2: Pendulum A simple pendulum a small weight attached to the end of a bismuth thread has a period of 3.4 when at a temperature of 13". The temperature then increases to 41"C. Determine the change in the pendulum's period period change 0.00125 Part 3: Standing waves in a string The fundamental frequency on a nickel string that is fixed at both ends is 65 H. The string is then change as a result assuming the tension remains constant ed 137c and as such its length changes. Determine how much the fundamental frequency will MacBook Air
