A spherical balloon is made from a material whose mass is 3.40 kg. The thickness of the material is negligible compared to the 1.40 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 280 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m³ and the molar mass of helium is 4.0026×10-3 kg/mol. Find the absolute pressure of the helium gas.
A spherical shell centered at the origin has an inner radius of 4 cm and an outer radius of 6 cm. The density, δ, of the material increases linearly with the distance from the center. At the inner surface, δ = 9 g/cm3; at the outer surface, g = 13 g/cm3 (a) Using spherical coordinates, write the density, δ, as a function of radius, p. (Type rho for ρ) (b) Write an integral in spherical coordinates giving the mass of the shell (for...
Steel has a density of 8.0 g/cm3. Let's plan building a spherical shell, made out of 2.0 cm thick steel. The perfectly spherical shell will have outer diameter of 2.0m. You can think of such a shell as a solid sphere, and then you cut out a sphere that has a 2.0cm smaller radius. 2. How heavy is that hollow sphere? Would this sphere float in water? a. b.
2. A spherical balloon is made from a material whose mass is 3.30 kg. The thickness of the material is negligible compared to the 1.55 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 295 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m3 and the molar mass of helium is 4.0026x10-3 kg/mol. Find the absolute pressure of the helium gas. Pa
