Suppose that the mass of the Earth doubles, but it maintains the same density and the same spherical shape. How would the weight of objects change on the Earth's surface?
A proposed space station consist set of a circular tube that will rotate about its center (like a tubular bicycle tire), Fig. 5-39. The circle formed by the he told Uber has a diameter of 1.1 km. What must be the rotation speed (revolution still per day) if an effect nearly equal to gravity at the surface of the Earth (say, 0.90 g) is to be felt?
When will you attract the sun more: today at noon, or tonight at midnight? Explain.
