According to the slope of the line, what is the mass of the Earth?
If the Earth's actual mass is recorded as 5.98 x 10
^{24}
kg, what is the accuracy of this data?
Using the equation of the line for this data, interpolate the orbital radius of a satellite that takes one day, or 24 hours, to make one revolution around the Earth.
