Answer:
Option A is correct.
Eddies due to enhanced mixing of fluid
Explanation:
Turbulent thermal conductivity is thermal conductivity that arises from the turbulent flow of fluids. It comes into play when a particukar fluid moves into turbulent regiom of flow where flow is no longer orderly and streamlines aren't discernable with the fluid layers all warping into one another forming vortices.
It is represented as K and is shown mathematically through the heat flux at turbulent flow
q = vCρT' = - K (∂T/∂y)
where
K = turbulent thermal conductivity
T' = the eddy temperature relative to the mean value,
C = Heat capacity the fluid
q = the rate of thermal energy transport by turbulent eddies.
The physical mechanism that cause turbulent thermal conductivity are similar to the causes of turbulent flow of fluids.
This includes sharp changes in fluid pressure and velocity of flow which is evident in eddies that come about in the enhanced mixing of fluids.

Answer: (A) 3.0=A
Explanation: In order to explain this problem we have to use the OHM law, given by: V=R*I
Besides, we have to consider the resitance equivalent for a parallel connection. This is given by:
1/Re=1/R1+1/R2
If we connect the same resistance, the equivalent resistance is R/2.
Initlally the current is 1.5 A when one resistance is connected to the batttery. When a second resistance with the same value is connected in parallel to the battery, we have V=Re*Ifinal= (R/2)*Ifinal
also we know that V=R*Iinitial so Iinitial=V/R
then Ifinal= 2*V/R=2*Iinitial
