Solving appled density problems Archimedes telis us the lifting power of a balioon (how much mass it can lift) is equal to the dilference between the mass of the balloon and the mass of the air it displaces. That is, if the barlogn occuples the same volume as 10kg of air, but the balloon only waighs 2kg, then the basoon can lit 8kg Airships have sometimes been filled with hydrogen (H2), but hydrogen is very flammable, and atter the Hindenburg caught fire and crashed in 1937 with serious loss ot life airships have nearly always been filled with helium (he) instead. Suppose n nee alrthip Star of Balogna wil have the shape of a chander 40 . m long, with a radlus of 4.0m, and war woigh 850 , kg without any gas inside ic Suppose atio the average passenger weighs 80kg : Calculate how mary passongers the Bologna couls carry if it were filled with hydrogen, and also if it were nilled with heilum
