A simple pendulum has a length of 45 cm. When the pendulum arm is rotated to an initial angle of 12 degrees from the vertical and released, it swings with a period of 0.60 seconds. If the pendulum arm is instead rotated to an initial angle of 6 degrees from the vertical and released, what will its new period be?
