11. The orbit of the international space station's (ISS) is nearly circular, is about 413 km above the Earth's surface, and has a period T of 92.7 minutes. Given that the Earth's radius is 6,378 km, determine the magnitude of acceleration of the ISS as a fraction of
$$g = 9.80 \frac{m}{s^2}$$. Hint: draw a picture of the situation first!
a. $$a = 0.032 g$$
b. $$a = 0.054 g$$
c. $$a = 0.93 g$$
d. $$a = 0.88 g$$
e. $$a = 1.1 g$$
