Extracted text: A helium balloon is inflated to 1.08 bars (gauge) and released. It has a diameter of 0.3 m and can be assumed to be a smooth sphere. The mass of the latex balloon material is 3 g. The surrounding air is at 20°C. (a) Considering that the helium is pressurized, what is the density of the helium? (b) What is the total weight of the balloon including the helium and latex? (c) What is the magnitude of the buoyancy force? (d) What is the fastest upward velocity of the balloon? Don't account for elevation affecting the surrounding air properties.
