The Moon has a mass of M = 7.3·1022 kg,a radius of R = 1.7·106 m and a rotation period of T = 27.3 days.Scientists are planning to place a satellite around the Moon that always remains above the same position (geostationary). (a)Calculate the distance from the Moon’s surface to this satellite. (b)Explain if such a Moon satellite is possible in reality.

B.2 This question concerns the possible tidal disruption of a spherical moon on a circular orbit of radius r about a host planet. The planet has mass Mp, radius R and mean density pp; the moon has mass M, radius Rm rand mean density Pm You may ignore any forces beyond the moon-planet system. (i) Show that tidal forces lead to a differential acceleration, between the face of the moon closest to the planet and the moon's centre, of amplitude...

An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1960 x 103 seconds (about 23 days) on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 295.0 x 106 m and the planet has a radius of 3.70 x 10% m, calculate the moon's radial acceleration a.

The mass of the moon is 7.34 × 1022 kg, and its radius is about 1.74 × 106 m (a) What is the value of “gmoon”, that is, the acceleration of gravity for a falling object near the surface of the moon? (b) What is the escape speed (from the moon) for an object on the surface of the moon? (c) What is the escape speed from the earth for an object that is as far from the earth as...

A gramophone record consists of a uniform circular disk of radius R and total mass M with a hole punched through it's center with a radius r. a) Show that the moment of inertia of the record about the perpendicular axis passing through it's center is 1/2 M(R^2 + r^2). b)A gramophone record having a mass of m=100g, radius =15cm and hole of radius 3cm is rotating freely on a turntable at 33 revolutions per minute with no friction. A...

Moon effect. Some people believe that the Moon controls their activities. If the Moon moves from being directly on the opposite side of Earth from you to being directly overhead, by what percentage does (a) the Moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? Assume that the Earth–Moon (center-to-center) distance is 3.82 × 108 m, Earth's radius is 6.37 × 106 m, Moon's mass is 7.36 × 1022 kg, and Earth's mass...
