Asimple pendulum consists of a brass sphere of mass m = 1 kg suspended on a string of length l β 1 meter. the pendulum oscillates with amplitude a = 1 cm and period t = 2 seconds. which of the following alterations will change the period of the pendulumβs oscillations to t β² = 1 second? 1. using a lighter brass sphere of mass m β² β 0.25 kg. 2. using a shorter string of length l β² β 0.25 meters. 3. using a longer string of length l β² β 2 meters. 4. using a longer string of length l β² β 4 meters. 5. using a shorter string of length l β² β 0.5 meters. 6. increasing the oscillation amplitude to a β² = 4 cm. 7. using a heavier brass sphere of mass m β² β 4 kg. 8. reducing the oscillation amplitude to a β² = 0.25 cm.
