Question

A balloon filled with a lighter gas occupies a volume of 1500 m^3

Answer 1

Answer:

The volume of the balloon is =1500m3. The density of air is. ρ=1.3kgm−3. The acceleration due to gravity is g=9.8ms−2........................

Answer 2

Answer:

hi,

A floating object displaces its own weight/mass of the fluid it floats in.

air density = 1.3 kg/m³

volume of balloon = 1500 m³

mass of balloon + mass of gas in it = 1650 kg

volume of air displaced by balloon and gas in it = (1650)/1.3 = 1269 m³

excess volume = 1500 - 1269 = 231 m³

mass of air in excess volume = 231(1.3) = 300 kg

force of gravity on excess mass of air = 300(9.81) = 2946 N
