As the length of simple pendulum increases, the period of oscillationAremains constantBdecreasesCincreasesDnone of theseAnswer: C. increases Read Explanation: The length of the string affects the pendulum's period. That is, the longer the length of the string, the longer the pendulum's period.The formula for determining the period of a pendulum is T = 2π √L/g, where,L - the length of the pendulum g - acceleration due to gravity Read more in App
