Objects 1 and 2 attract each other with a gravitational force
of 36.0 units. If the mass of Object 1 is halved, then the new
gravitational force will be units.

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
