<span>Even though the Sun has a greater mass than Earth, the Moon orbits Earth because it's closer to the Earth than to the Sun. Because of this proximity between the Earth and the Moon, the Earth has a stronger gravitational pull than the Sun does. Furthermore, the Earth's mass is 81 times that of the Moon, and so at this proximity, it is more than able to overpower what pull the Sun exerts on the Moon.</span>
Answer:
Clockwise
Explanation:
All of the planets rotate the same way around the sun.
Answer:
![\Delta T = 52.6 ^o C](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%2052.6%20%5Eo%20C)
Explanation:
As we know that radius of the brass ring is given as
![R_{brass} = 1.0000 cm](https://tex.z-dn.net/?f=R_%7Bbrass%7D%20%3D%201.0000%20cm)
radius of the sphere is given as
![R_{sphere} = 1.0010 cm](https://tex.z-dn.net/?f=R_%7Bsphere%7D%20%3D%201.0010%20cm)
now by thermal expansion formula we know that
![L = L_o(1 + \alpha \Delta T)](https://tex.z-dn.net/?f=L%20%3D%20L_o%281%20%2B%20%5Calpha%20%5CDelta%20T%29)
so we will have
![1.0010 = 1.0000(1 + (19\times 10^{-6})\Delta T)](https://tex.z-dn.net/?f=1.0010%20%3D%201.0000%281%20%2B%20%2819%5Ctimes%2010%5E%7B-6%7D%29%5CDelta%20T%29)
so we have
![\Delta T = 52.6 ^o C](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%2052.6%20%5Eo%20C)
