One possible unstructured activity that promotes resistance training would be climbing playground equimpent - A. 
This is by nature a unstructured ctivity. Furthermore, it promotes resistance training because you're forced to move and pull and push yourself. 
        
             
        
        
        
The atom must have gained 1 or more electrons or must have lost 1 or more electrons.
        
                    
             
        
        
        
Answer:
The x-component of the electric field at the origin = -11.74 N/C.
The y-component of the electric field at the origin = 97.41 N/C.
Explanation:
<u>Given:</u>
- Charge on first charged particle,  
- Charge on the second charged particle,  
- Position of the first charge =  
- Position of the second charge =  
The electric field at a point due to a charge  at a point
 at a point  distance away is given by
 distance away is given by

where,
 = Coulomb's constant, having value = Coulomb's constant, having value 
 = position vector of the point where the electric field is to be found with respect to the position of the charge = position vector of the point where the electric field is to be found with respect to the position of the charge . .
 = unit vector along = unit vector along . .
The electric field at the origin due to first charge is given by

 is the position vector of the origin with respect to the position of the first charge.
 is the position vector of the origin with respect to the position of the first charge.
Assuming,  are the units vectors along x and y axes respectively.
 are the units vectors along x and y axes respectively. 

Using these values,

The electric field at the origin due to the second charge is given by

 is the position vector of the origin with respect to the position of the second charge.
 is the position vector of the origin with respect to the position of the second charge.

Using these values,

The net electric field at the origin due to both the charges is given by

Thus, 
x-component of the electric field at the origin = -11.74 N/C.
y-component of the electric field at the origin = 97.41 N/C.
 
        
             
        
        
        
Explanation:
I think it will increase a little bit ... just image ... if the temperature is 0, the velocity will be 0 too. because the vibration of atom is so weak and the sound cant progation.
 
        
             
        
        
        
No 
It means the resultant electrical charges had canceled each other out so there is no field to be sensed .
