Buoyancy 39891

The balloon filled with hot air has a volume of 1440m3. How large a buoyancy force acted on the balloon in the air with a density of 1.3 kg / m3?

Correct answer:

F =  18364.32 N

Step-by-step explanation:

V=1440 m3 ρ=1.3 kg/m3  m=ρ V=1.3 1440=1872 kg  g=9.81 m/s2 F=m g=1872 9.81=18364.32 N
