A balloon is released from a tall building. The total mass of the balloon including the enclosed gas is 2.0 kg. Its volume is 5.0 m. The density of air is 1.3 kg/m. 12.What is the average density of the balloon? A) 0.2 kg/m B) 0.4 kg/m3 C) 0.8 kg/m D) 1.0 kg/m E) 1.2 kg/m 13. Will the balloon rise, fall, or remain stationary, and why? A) The balloon will fall because its density is greater than that of air. B) The balloon will remain stationary because its density is less than that of air. c) Tho balloon will riac booauco tho upword buoyant forco io groator than its woight. D) The balloon will fall bocause tho upward buoyant force is loss than its woight. E) The balloon will fall because the downward buoyant force is greater than the upward buoyant force.
