Alarge helium filled balloon is used as the center piece for a graduation party. the balloon alone has a mass of 225 kg and it is filled with helium gas until its volume is 323 m3.
assume the density of air is 1.20 kg/m3 and the density of helium is 0.179 kg/m3.

(a) calculate the buoyant force (in n) acting on the balloon. (enter the magnitude. round your answer to at least three significant figures.)

(b) find the net force (in n) on the balloon and determine whether the balloon will rise or fall after it is released. magnitude n direction rise d

(c) what additional mass (in kg) can the balloon support in equilibrium? (if the balloon will fall after it is released, enter 0.)
