Find a numerical value for ρ_earth, the average density of the earth in kilograms per cubic meter. Use 6378km for the radius of the earth, G=6.67×10−11m3/(kg⋅s2), and a value of g at the surface of 9.80m/s2.
13) For some pressure calculations density needs to be given in kilograms per cubic meter. Convert all the densities in #6 to kilograms per cubic meter. fare that is 1.75 cm X g a. Pine: 0.77 cm3 g b. Oak: 0.85 cm3 g C. Styrofoam: 0.050 cm3 a. g Pine: 0.77 cm3 b. Oak: 0.85 g cm3 C. Styrofoam: 0.050 g cm3
The Hindenburg was a 242-ton (220,000 kilograms) hydrogen-filled airship that ended in a disaster. The airship boasted 200,000 cubic-meters of volume and the lighter-than-air gas that filled it up was Hydrogen (a highly-flammable gas) instead of Helium. What was the maximum weight it was able to lift? The density 3 of gas at STP is 0.082 kg/m . Please show all work and write neatly :)
