2. A spherical balloon is made from a material whose mass is 2.60 kg. The thickness of the material is negligible compared to the 1.25 m radius of the balloon. The balloon is filled with helium (He) at a temperature of 325 K and just floats in air, neither rising nor falling. The density of the surrounding air is 1.19 kg/m² and the molar mass of helium is 4.0026x10-kg/mol. Find the absolute pressure of the helium gas. Pa

A helium-filled balloon, whose envelope has a mass of 0.26 kg,
is tied to a 3.6-m long, 0.053-kg string. The balloon is spherical
with a radius of 0.40 m. When released, it lifts a length
h of the string and then remains in equilibrium, as in the
figure below. Determine the value of h. Hint:
Only that part of the string above the floor contributes to the
load being supported by the balloon. (The density of air is 1.29
