Problem 25P

(II) A spherical balloon has a radius of 7.15 m and is filled with helium. How large a cargo cai it lift, assuming that the skin and structure of the balloon have a mass of 930 kg? Neglect the buoyant force on the cargo volume itself.

Step-by-Step Solution:

Solution 25P:

We have to calculate the maximum mass of the cargo that the balloon can lift from the given problem statement.
