(10%) Problem 4: A balloon filled with helium gas has an average density of Ob = 038 kg/m. The density of the air is about 9, = 1.23 kg/m . The volume of the balloon is V, = 0.063 m. The balloon floats upward with acceleration a. Wotton, Hannah - hannah.wotton @uconn.cdu a Otheexpertta.com @theexpertta.com - tracking id: 8C84-FD-99-45-BB64-16491.
