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 St. Petersburg, Russia and has a length of 0.99548 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

i think the answer is a, hope this : )

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
