How are objects in the sky used to measure longitude?

answer:

astronomers describe the position of objects in the sky by using coordinates. the easiest way to do this is to use coordinate systems which assume that all objects in space are at the same distance, on the inside of an imaginary celestial sphere.

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
