Determine the magnitude of Earth's gravitational field for \((a)\) a 70. 0-kg person standing at Earth's surface, \((b)\) a \(700.0-\mathrm{kg}\) satellite in orbit \(150 \mathrm{~km}\) above Earth's surface, and \((c)\) the Moon (use \(3.844 \times 10^{8} \mathrm{~m}\) for the center-tocenter distance between Earth and the Moon).
