9. (3 pts) The Spongebob Squarepants Macy's Thanksgiving parade balloon has a volume of 368 m3 The temperature for the parade is 45°F and the pressure is 0.987 atm, what mass of helium is in the balloon (in kg)?
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? Suggestion: Write Newton's Second...
