All parts please

1. While visiting the Chicago museum of Science and Industry, you notice the large simple pendulum swings hack and forth once every T = 4.4? seconds. a. b. c. d. Calculate the frequency of oscillation (in Hertz) of the pendulum. (1) Calculate the angular frequency to of the pendulum in radiansf second. (1) Determine the length L in meters of the pendulum. {3) That evening, your friend told you that the length of the pendulum is actually 5 m and its period is 0.02 seconds slower than what you have measured. Determine the acceleration due to gravity in 111st at the museum. (3) Would the frequency of this 5 m pendulum be more, less or stay the same if you take this exact pendulum on the moon where gravitational acceleration is much less gum] = 1.625 m/sz. Calculate and comment. (2)
