SUMMARY
The discussion focuses on calculating the height a helium balloon ascends using its mass and the density of helium and air. The balloon has a radius of 40 cm, an empty mass of 250 g, and is tethered by a 2-meter thread weighing 50 g. The density of air is 1.29 kg/m³, while helium's density is 0.179 kg/m³. The key to solving the problem lies in determining the mass of the thread in relation to its length h, which is calculated as 25h grams, allowing for further calculations to find the height h.
