A tuned mass damper at the top of a skyscraper acts like a simple pendulum. If it sways with a frequency of 0.125 Hz, what is its length? (Assume the strength of Taipei's gravitational field to be 9.81 N/kg.) The length of the pendulum is_____-m. How many oscillations PER MINUTE does 0.125 Hz represent? А. 1.25 х 10-1 oscillations B. 1.33 x 10 oscillations C. 7.50 oscillations D. 8.00 oscillations
