The Moon completes one orbit around the Earth in approximately 27.3 days. What is the angular speed of the Moon in its orbit?
1.5×10−7 rad s−11.5 \times 10^{-7} \text{ rad s}^{-1}1.5×10−7 rad s−1
2.7×10−6 rad s−12.7 \times 10^{-6} \text{ rad s}^{-1}2.7×10−6 rad s−1
7.3×10−6 rad s−17.3 \times 10^{-6} \text{ rad s}^{-1}7.3×10−6 rad s−1
3.8×10−5 rad s−13.8 \times 10^{-5} \text{ rad s}^{-1}3.8×10−5 rad s−1
