On a perfect fall day, you are hovering at low altitude in a hot-air balloon, accelerated neither upward nor downward. The total weight of the balloon, including its load and the hot air in it, is 24000 N.
Find the weight of the displaced air.
I got the weight=2.4×10^4 N but not the displaced air!!
Find the volume of the displaced air.
