hey what is this 2 in between the question
please tell 
 
        
             
        
        
        
To solve this problem it is necessary to apply the concepts related to rate of thermal conduction

The letter Q represents the amount of heat transferred in a time t, k is the thermal conductivity constant for the material, A is the cross sectional area of the material transferring heat,  , T is the difference in temperature between one side of the material and the other, and d is the thickness of the material.
, T is the difference in temperature between one side of the material and the other, and d is the thickness of the material. 
The change made between glass and air would be determined by:





There are two layers of Glass and one layer of Air so the total temperature would be given as,




Finally the rate of heat flow through this windows is given as,



Therefore the correct answer is D. 180W.
 
        
             
        
        
        
A. anything less than 3.0 magnitude on a richters scale usually can't be felt by humans but instruments can pick it up.
 
        
                    
             
        
        
        
Answer:
<em>likely to decrease downstream in arid regions and increase downstream in temperate regions</em>
<em></em>
Explanation:
Arid regions are is a region with a severe lack of water, usually to the extent that affect the organisms living in the region. Arid regions are characterized by a very low depth of rainfall per year. Temperate region on the other hand experience more distinct seasonal change and wider temperature change. Temperate regions get a fairly large amount of rainfall per year.
In arid regions, the soil is very dry, and the rate of infiltration and percolation is high relative to the amount of rainfall available. The effect is that more water is infiltrated into the soil as you move downstream, leading to a decrease in the discharge of a stream as you move downstream. Most temperate region have soils that are usually saturated in the peak of the rainfall season, leading to a greater stream discharge as you move downstream.
