A hydrogen-filled blimp cruises slowly at a low altitude. Its maximum useful payload, including crew and cargo, is 6,857 kg. How much less payload can be carried if the blimp were filled with helium? Use for the volume of the gas-filled interior space a value of 1,332 m3. The density of helium gas is 0.16 kg/m3 and the density of hydrogen gas is 0.08 kg/m3.
Express result as a positive number in the unit [N] (i.e.. the payload's weight) and to three significant figures. If you must use scientific notation, please enter as follows: e.g. 0.000123 = 1.23E-4.
