Aspherical balloon has a radius of 6.55 m and is filled with helium. the density of helium is 0.179 kg/m3, and the density of air is 1.29 kg/m3. the skin and structure of the balloon has a mass of 990 kg . neglect the buoyant force on the cargo volume itself. part a determine the largest mass of cargo the balloon can lift. express your answer to two significant figures and include the appropriate units.

Explanation:

Mass of the helium gas filled inside the volume of balloon is given as

now total mass of balloon + helium inside balloon is given as

now we know that total weight of balloon + cargo = buoyancy force on the balloon

so we will have

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
