Ahot-air balloon consists of a basket hanging beneath a large envelope filled with hot air. a typical hot-air balloon has a total mass of 539 kg, including passengers in its basket, and holds 2.62 ✕ 103 m3 of hot air in its envelope. if the ambient air density is 1.27 kg/m3, determine the density (in kg/m3) of hot air inside the envelope when the balloon is neutrally buoyant. neglect the volume of air displaced by the basket and passengers. hint kg/m3

1.05045 kg/m³
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
v = Volume of air in balloon =![2.62\times 10^3\ m^3](/tpl/images/0406/1680/cf6c2.png)
The net force on the balloon will be
