The acceleration due to gravity becomes weaker by about
Chapter 12, Problem 1(choose chapter or problem)
The acceleration due to gravity becomes weaker by about three parts in ten million for each meter of increased elevation above the Earths surface. Suppose a skyscraper is 100 stories tall, with the same floor plan for each story and with uniform average density. Compare the location of the buildings center of mass and the location of its center of gravity. Choose one: (a) Its center of mass is higher by a distance of several meters. (b) Its center of mass is higher by a distance of several millimeters. (c) Its center of mass and its center of gravity are in the same location. (d) Its center of gravity is higher by a distance of several millimeters. (e) Its center of gravity is higher by a distance of several meters.
