Plaster Mix Ratio
Mix cement and sand in the ratio of 1:6 (1 cement:6 sand) for inner plastering of bricks. And for outer plastering mix it in the ratio of 1:4. On a brick wall never do plastering of thickness more than 12 or 15mm. At one go, avoid plastering of more than 12mm thickness.
Answer:
point B where 
has the largest Q value at section a–a
Explanation:
The missing diagram that is suppose to be attached to this question can be found in the attached file below.
So from the given information ;we are to determine the point that has the largest Q value at section a–a
In order to do that; we will work hand in hand with the image attached below.
From the image attached ; we will realize that there are 8 blocks aligned on top on another in the R.H.S of the image with the total of 12 in; meaning that each block contains 1.5 in each.
We also have block partitioned into different point segments . i,e A,B,C, D
For point A ;
Let Q be the moment of the Area A;
SO ; 
where ;
For point B ;
Let Q be the moment of the Area B;
SO ; 
where ;
For point C ;
Let Q be the moment of the Area C;
SO ; 
where ;
For point D ;
Let Q be the moment of the Area D;
SO ; 
since there is no area about point D
Area = 0
Thus; from the foregoing ; point B where has the largest Q value at section a–a
Answer:
0.9VDC
Explanation:
When testing transistors, it is important to use 0.9 VDC minimum voltage difference across the base-emitter junction.
Answer: True
Explanation: Yes , we can recycle glass endlessly, as many times as we want without the degradation of quality and purity factor because they are made from the widely available domestic components for example:- sand , limestone etc. These material are responsible for the successful recycling process of glass which does not produce any loss.
