Find the radius r of the orbit of a geosynchronous satellite that circles the earth. (note that r is measured from the center of the earth, not the surface of the earth.) use the following values if needed in this problem:
1) the universal gravitational constant g is 6.67×10−11nm2/kg2.
2) the mass of the earth is 5.98×1024kg.
3) the radius of the earth is 6.38×106m.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
