Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...

12) Consider a party balloon filled with helium with a small mass m hanging from it, as depicted in Figure 2. The balloon can be approximated as a sphere with volume V = 0.035 m. The mass of the rubber and string (i.e. the balloon's mass when it is not filled with helium) is 0.0025 kg. a) If the balloon with the mass hanging is floating in equilibrium, what is the value of the hanging mass?
