Using knowledge of hydrostatics, estimate the total mass of the earth's atmosphere by using atmospheric pressure and the earth's surface area. Show all work.
Acceleration of Gravity 6 Re 2R 4R Re Distance from Earth's Center 24 Earth's average sea level radius is 6.37 x 10 m, and the mass of the Earth is 5.98 x 10 kg.The gravitational constant, G = 6.67 x 10"N-m/kg . What is "g" at a distance of 2R from the center of the Earth? 2 Select one: a. 4.9 m/sec b. 1.25 m/sec? O c. zero, because you are weightless in space 2 O d. 2.45 m/sec
2. Atmospheric Mass Venus and Earth have about the same mass and radius, but the atmospheric pressure on the surface of Venus is measured to be 90 times larger than the pressure at the surface of the Earth. (a) Assuming Venus' atmosphere is pure CO2 and Earth's atmosphere is pure N2, estimate the atmospheric scale height for each planet. For simplicity you can assume that both atmospheres are isothermal with T = 550 K for Venus and T = 250...
The Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x10^5 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 10.2 m long and 14.5 m wide?
Concern has been expressed that warming of the atmosphere, resulting from industrial pollution, could cause the polar ice caps to melt. If the polar ice caps of the earth were to melt and the water returned to the oceans, the oceans would be made deeper by about 44.7 m. This will effect the earth's rotation. Make an estimate of the resulting change in the length of the day, assuming that all of the earth's surface is covered with oceans. Assume...
