Two high precision pendulums move through their equilibrium positions once each second, so that the periods of each is precisely 2.000 s. One of them is in Copenhagen, Denmark and has a length of 0.99503 m. The other is in Quito, Ecuador and has a length of 0.98963 m. What is the ratio of the free-fall acceleration of gravity g at these two cities

Greg drew a diagram to compare two of the fundamental forces. which labels belong in the areas marked x, y and z? gravitational force electromagnetic force x. attractive y repulsive z: infinite range x: infinite range y attractive z. repulsive x. always attractive y: infinite range z: attractive or repulsive x. attractive or repulsive y infinite range z: always attractive
