Afan-shaped auditorium has inner radius of rₐ and outer radius of rₑ with angle of a.
the stage (at the center r ∂u/∂t=c²*(∂²u/∂r²+1/r*∂u/∂r+1/r²*∂² u/∂θ²)
a. derive the steady-state temperature distribution in the auditorium.
b. how would you expect the temperature distribution changing if the thermal diffusivity of air changes to (2c)² and why?

if they have a finite resultant

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
