I have a balloon that has a mass of 11 g. When I fill it up with helium such that it blows up to a perfect spherical shape with diameter of 50 cm. 2.1 Determine the overall mass of the blown-up balloon Take the density of helium to be 0.1785 kg/m3 (5) (2) 2.2 Will the balloon float or will it fall down if it is held by a string 2.3 Explain your answer in 2.2 using the Archimedes principle (3) 2.4 Determine the tension in the string Assume the skin of the balloon has negligible volume (4) 2.5 If the string is suddenly cut, determine the time it takes for the balloon to rise up to 100 m from the original height. Ignore changes in atmospheric pressure and also drag force on the (6) balloon. I have a balloon that has a mass of 11 g.
