In the novel rendezvous with rama by arthur c. clarke, rama is a gigantic space craft of alien origins. it is detected passing jupiter's orbit at a velocity towards the sun of 100 000 km/h. upon closer observation it is found that rama is a perfect cylinder; the interior is 50 km long with a diameter of 16 km; and it rotates once every 4 minutes. (a) is rama in an orbit bound to the sun? (jupiter's orbital radius is 5au) (b) is there gravity inside rama? if so how strong is it? could there be a breathable atmosphere with this gravity? (c) access to the interior is from airlocks located at the centre of the ends of the cylinder. there are then a series of ladders and stairs from the centre to the "surface" of rama. as the astronauts climb down the ladder they feel a force perpendicular to the ladder why is this? which direction is it in? (d) halfway along the long axis of rama in the interior there is a moat along the curved surface that forms a annular or cylindrical "sea". it is 10 km wide, with only a shal- low retaining cliff on one end but a 500 m high cliff at the other end. what is the maximum acceleration possible without the sea going over the high cliff? (e) assuming that rama's skin is about 1 km thick and that it's made out of material the same density as steel, how much rotational energy is stored in the rotation?

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
