The mean radius of the Earth is 6.37 x 106 m, and that of the Moon is 1.74 x 108 cm. From these data calculate (a) The ratio of the Earth’s surface area to that of the Moon and (b) The ratio of the Earth’s volume to that of the Moon. Recall that the surface area of a sphere is 4πy2 and the volume of a sphere is 4/3 πr3
Answer to relevant QuestionsOne cubic meter (1.00 m3) of aluminum has a mass of 2.70 x 103 kg, and 1.00 m3 of iron has a mass of 7.86 x 103 kg. Find the radius of a solid aluminum sphere that will balance a solid iron sphere of radius 2.00 cm on an ...Approximately how many raindrops fall on a one-acre lot during a one-inch rainfall? Explain your reasoning.The radius of a solid sphere is measured to be (6.50 ± 0.20) cm, and its mass is measured to be (1.85 ± 0.02) kg. Determine the density of the sphere in kilograms per cubic meter and the uncertainty in the density.The consumption of natural gas by a company satisfies the empirical equation V = 1.50t + 0.008 00t 2, where V is the volume in millions of cubic feet and t the time in months. Express this equation in units of cubic feet and ...A creature moves at a speed of 5.00 furlongs per fortnight (not a very common unit of speed). Given that 1 furlong = 220 yards and 1 fortnight = 14 days, determine the speed of the creature in m/s. What kind of creature do ...
