Find the minimum radius of a helium balloon that will lift her off the ground. the density of helium gas is 0.178 kg/m3, and the density of air is 1.29 kg/m3. neglect the weight of the deflated balloon itself (but not the weight of the helium). assume that the shape of the balloon is a sphere. neglect the buoyant force of the air on the woman.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
