- Four small spheres of mercury coalesce to form a single sphere. Compared with the combined surface area of the smaller spheres, the surface of the big sphere is Chose the correct answer: more. triple than the small spheres. double than the small spheres. less.A)At what altitude would a geostationary sattelite need to be above the surface of Mars? Assume the mass of Mars is 6.39 x 1023 kg, the length of a martian solar day is 24 hours 39minutes 35seconds, the length of the sidereal day is 24hours 37minutes 22seconds, and the equatorial radius is 3396 km. The answer can be calculated using Newton's verison of Kepler's third law.2. A comet is traveling in outer space with a velocity of 2000 m/s.
