- P Some fish have a density slightly less than that of water and must exert a force, by swimming, to stay barely submerged. What magnitude of force, in newtons, must an 82-5-kg grouper exert to stay submerged in salt water (with density 1025 kg/m³) if its body density is 1015 kg/m³?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!
