You have selected the correct answer and blobbed over it with your pencil.

I assume you must have looked at Saturn's average distance, found 1427,
divided that number by 6, got 237 and change, then looked at the others,
and found that 228 was the only one that's anywhere close.

Answer:

Mars

Explanation:

The distance between Sun and Saturn = 1427 Million km

one sixth of the distance between Sun and Saturn will be

$= \frac{1427\times 10^{6} }{6} km$

= 237.83 Million km

From the given data it is evident that the right answer will be Mars.

As the distance between Mars and Sun is 228 million km which is the closest value to the one sixth of the distance between Sun and Saturn.

Identify the physical mechanism that causes turbulent thermal conductivity.

myrzilka [38]

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.

Hope this Helps!!!

According to the Second Law of Thermodynamics, a. any process during which the entropy of the universe increases will be product

Iteru [2.4K]

Answer:

The correct option is;

a. Any process in which the entropy of the universe increases will be product-favored

Explanation:

According to the second law of thermodynamics, the change in entropy of a closed system with time is always positive. That is the entropy of the entire universe, considered as an isolated system, always increases with time, hence the entropy change in the universe will always be positive.

$\Delta S_{universe} = \Delta S_{system} + \Delta S_{surroundings} >0$

Therefore, any process in which the entropy of the universe increases will be product favored.
