While the Earth spins around its axis and orbits around the sun, then suppose we remove the sun from its location, will Earth continue to spin around its axis and orbits around the point where the sun used to be? Why or why not?
Calculate the force of gravity on the same 1-kg mass if it were 6.4 × 10 6 m above Earth’s surface (that is, if it were two Earth radii from Earth’s center).
If somebody tugged hard on your shirt sleeve, it would likely tear. But if all parts of your shirt were tugged equally, no tearing would occur. How does this relate to tidal forces?

Remember that the Moon keeps one side toward Earth at all times.Discuss whether the values found in both parts seem consistent with the fact that tidal effects with Earth have caused the Moon to rotate with one side always facing Earth.arrow_forward
- If the semi-major axis, a, is measured in AU and the orbital period, p, is measured in years, then Kepler's 3rd law allows us to calculate the mass of the object they are orbiting using the following equation: M = a3/p2 Furthermore, the mass that is calculated by this equation is given in solar masses (MSun) where, by definition, the Sun's mass is 1 MSun. Now, suppose I were to tell you that the mass of Jupiter is equal to 4.5e7 MSun.

What is the maximum interval the satellite could maintain a communication link with a ground station? Assume the satellite passes directly overhead the station, but must be at least 15° above the horizon to establish and maintain the communication link. Report your answer in minutes using three significant digits (e.g. 123).
