Say the density of air is 1.23 kg/m3 and the density of helium
is 0.164 kg/m3 when both are at STP. Let's model a balloon as a
sphere of radius 0.12 m, with mass 2 g.
1) What is the mass of the helium that would fill a single
balloon?
2) What is the buoyant force on a single balloon?
3) What is the net force on a single balloon?
4) If we attach 0.5 m of string (properties: 800...

Would the speed of sound in a monatomic gas like helium be the
same as it would be in air (primarily a diatomic gas)? Why? Assume
that both gases have the same density and exist at the same
pressure.
Yes. If the pressure and density of both gases are the same,
then the speed of sound must be the same.
No. The energy that goes into molecular bonds in the diatomic
gas makes the effective spring constant of the gas...

A helium balloon ride lifts up passengers in a basket. Assume
the density of air is 1.28 kg/m3 and the density of
helium in the balloon is 0.18 kg/m3. The radius of the
balloon (when filled) is R = 5.2 m. The total mass of the empty
balloon and basket is mb = 126 kg and the total volume
is Vb = 0.068 m3. Assume the average person
that gets into the balloon has a mass mp = 73 kg...
