Question: A balloon filled with helium gas has an average density of qb = 0 . 3 1 kg / m ^ 3 . The density

A balloon filled with helium gas has an average density of qb =0.31 kg/m^3. The density of the air is about Qa =1.23 kg/m^3. The volume of the balloon is Vb =0.048 m^3. The balloon is floating upward with accelerationa. Express the weight of the balloon, W, interms of qb and Vb. Calculate the numerical; value of W in N. Express the buoyant Fb in terms of Qa and Vb. Calculate the numerical value of Fb in N/Express the total force F in terms ofW and Fb assuming tupward is the positive direction. Calculate the numerical value of F Ian N.Express the acceleration a in terms of F, Qb and Vb. Calculate the numerical value of a in m/s^2
