Question #b0cef
1 Answer
The mass of air inside the balloon is 630 kg.
The total weight of the balloon is 8900 N.
Explanation:
So, you know that you have a balloon filled with air. The volume of the balloon is equal to
The density of the air will tell you what mass of air occupies exactly
To get the total weight of the balloon, you need to calculate its total mass first. Since the material and equipment add a mass of 280 kg to the mass of air, the total mass will be
This means that the total weight of the balloon will be
I'll leave both values rounded to two sig figs, despite the fact that you only gave one sig fig for the volume of the balloon.
