What effect did changing the angle have on the period of oscillations? a. As the angle increased, the period decreased. b. The angle has no effect. c. When the angle was less than 15 degrees, changing the angle had no effect on the period. When the angle was much larger, the period was shorter. d. When the angle was less than 15 degrees, changing the angle had no effect on the period. When the angle was much larger, the period...
