A helium balloon (in the shape of a sphere) has radius 7.10 m. For the density of air, please use 1.29 kg/m^3, and for Helium, use .179 kg/m^3 - Part A How much additional mass (payload) could this balloon lift? You should assume the balloon's skin, plus other parts of the balloon's structure have a total mass of 900 kg. Note however that this number does NOT yet include the mass of the helium filling the balloon, which you will need to account for! Express your answer using two significant figures. ▸ View Available Hint(s) m = for Part A for Part A undo for Part A redo for Part A reset for Part A keyboard shortcuts for Part A help for Part A Submit kg

Answer all parts!   Part A -  A cube of side length 21.0 cm floats in oil, 18.0% of its volume is in oil as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. Compare the volume of the cube Vcube and the volume displaced by oil Vdisplaced.       Answers: Vdisplaced = 0.18*Vcube   Vdisplaced = 0.5*Vcube   not enough information   Vdisplaced = 0.82*Vcube   Vdisplaced = Vcube   Part B - A cube of side length 21.0 cm floats in oil, 18.0% of its volume is in oil as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. What is the magnitude of the buoyant force on the cube, in Newton?   Part C - A cube of side length 21.0 cm floats in oil, 18.0% of its volume is in oil as shown. Use g = 10.0 m/s2. The density of the oil is 900 kg/m3. What is the density of the cube, in kg/m3?
