9. The "seconds" pendulum in a pendulum clock built for a 19th century astronomical observatory has a period of exactly 2.0 seconds, so each one-way motion of the pendulum takes exactly 1.0 seconds. What is the length of such a "seconds" pendulum at a place where the acceleration of gravity is 9.79 m/s²?
