Q1) Atmospheric pressure near the Venusian surface is 92
times larger than the standard atmospheric pressure at sea level on
Earth, so Venusian ATVs are built like tanks to avoid getting
crushed like a soda can. The company that builds them is stationed
on Earth where new ATVs are field tested during deep sea dives. To
what depth must a vehicle be submerged in Earth’s ocean to
approximate the atmospheric conditions on the surface of
Venus?
A. 500 m B. 900 m C. 1300 m D. 1700 m
Q8) The surface gravity of Venus is similar to that of
Earth, but the density of the Venusian atmosphere is 65 kg/m3 at
the planet surface. This gives tourists a spring in their step when
they exit their ATVs to go for a stroll on foot as the buoyancy of
the atmosphere reduces their apparent weight. How does a person’s
apparent weight compare to their actual weight on Venus? Assume the
average density of the human body is 985 kg/m3.
A. apparent = 6.6 % of actual B. apparent = 15.2 % of
actual C. apparent = 84.8 % of actual D. apparent = 93.4 % of
actual
Q9) While traveling between worlds, the cylindrical
cruise ship spins to simulate Earth gravity for its passengers. As
the occupants walk along the inner surface of the cylinder, they
feel stuck to the “ground” just as if they were walking on Earth.
How quickly must a ship with a diameter of 200 m spin in order to
simulate 1 g? Give your answer in revolutions per
minute.
