Answer:
C = 17 i^ - 7 j^ + 16 k^
,   | C| = 24.37
Explanation:
To work the vactor component method, we add the sum in each axis
C = A + B = (Aₓ + Bₓ) i ^ + (
 + 
) i ^ + (
 + 
) k ^
Cₓ = 12+ 5 = 17
 = -37 +30 = -7
 = 58 -42 = 16
Resulting vector
C = 17 i ^ - 7j ^ + 16k ^
The mangitude of the vector is
| C | = √ c²
| C | = √( 17² + 7² + 16²)
| C| = 24.37
 
        
             
        
        
        
Answer:
v =2.02
Explanation:
v^2=0.05-4.9
v^2=-4.85
square root both side 
v=2.02
^^^^this is a not a perfect square  
 
        
             
        
        
        
Although the sample is not shown in this question, we can conclude that it would be reasonably easy for David to provide evidence of the color, consistency, temperature, and texture of the soil.
<h3 />
<h3>What are these properties an example of?</h3>
These are all examples of the physical properties of a sample. Since we cannot see the sample that David is using, it would be safest to assume that he would have no trouble providing evidence as to the physical properties of the soil, the: 
- Color
 - Consistency
 - Temperature
 - Texture
 
are all examples of this. 
Therefore, we can confirm that David can provide evidence of the color, consistency, temperature, and texture of the soil.

Answer:
the electric field strength of this charge is two times the strength of the other charge
Explanation:
Using the relationship between electric field and the charge, which is inversely proportionality. Let the the magnitude of the first charge be Q and the respective electric field be E. It implies that;
E1/E2 = Q2/Q1
E2 = E1 x Q1/Q2
       = E x Q/ (Q/2)
        = 2E
