A sirmple pendulum consists of a brass sphere of mass m = 1-kg Suspended on a string of length L1-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 pendulum's oscillations to T' 1 second? 1 Using a longer string of length E4-meters 2 Using a shorter string of lengthE0.25-meters. O 3. Increasing the oscillation amplitude to A'= 4-cm. O 4. Using a lighter brass sphere of mass m R 0.25-kg. O 5. Using a heavier brass sphere of mass ma's 4-kg. O 6. Reducing the oscillation amplitude to A' 0.25-cm. O 7. Using a longer string of length L' 2-meters. O 8. Using a shorter string of length L' 0.5-meters.
