A mountain climber with a mass M ponders the idea of attaching a helium-filled balloon to himself to reduce his weight, so his effective weight will be P*Mg, where P is a numerical factor in the range of 0.0 .. 1.0:
When P = 0.0, the climber will be just barely floating above the surface
When P = 1.0, there is no lifting at all
Density of the Air = 1.21 kg/m3
Density of Helium = 0.178 kg/m3
If the balloon is perfectly spherical, calculate it's diameter provided the following values:
M = 70 kg
P = 0.9 .
The balloon itself is Physics-1010 perfect, i.e. the shell of the balloon is zero mass.
Enter two digits after the decimal point.
