Hi. Can someone please walk me through the following problem?
A 0.12 kg balloon is filled with helium (density = 0.179 kg/m^3). If the balloon is a sphere with a radius of 5.2 m, what is the maximum weight it can lift?
This solution is provided in a 1 page .pdf file attached. It describes how to calculate total mass of helium in the balloon as well as net system weight. It provides guidance for the student to reach the answer themselves.
