A hot air balloon has a volume of 440 x 10^3 calculate the buoyant force that the surrounding cold air exert on the balloon given that the density of the surrounding is 2.58 kg/m3.
Answers
Answer:
Buoyant Force = Weight of the volume of cold air displaced by the balloon due to it's presence. (That's what actually archimedes noticed)
So how to find -- Weight of the volume of cold air displaced by the balloon due to it's presence?
What is the volume displaced? 440000m³? Then how much mass does this volume of air correspond to? Think about it! and atlast multiply the mass with "g" to get the right answer!
