Answer:  
 
Explanation:
According to <u>Coulomb's Law:</u>  
<em>"The electrostatic force  between two point charges
 between two point charges  and
 and  is proportional to the product of the charges and inversely proportional to the square of the distance
 is proportional to the product of the charges and inversely proportional to the square of the distance  that separates them, and has the direction of the line that joins them".</em>
 that separates them, and has the direction of the line that joins them".</em>
<em />
Mathematically this law is written as: 
 
  
Where:
 is the electrostatic force
  is the electrostatic force
 is the Coulomb's constant
 is the Coulomb's constant  
 and
 and  are the electric charges
 are the electric charges
 is the separation distance between the charges
 is the separation distance between the charges 
Solving:
 
  
 
    
 
        
             
        
        
        
Answer:
The moment is 81.102 k N-m in clockwise.
Explanation:
Given that,
Force = 260 N 
Side = 580 mm
Distance h = 370 mm
According to figure,
Position of each point
 
 
 
We need to calculate the position vector of AB


We need to calculate the unit vector along AB


We need to calculate the force acting along the edge 


We need to calculate the net moment 

Put the value into the formula




Put the value into the formula


Negative sign shows the moment is in clockwise.
Hence, The moment is 81.102 k N-m in clockwise.
 
        
             
        
        
        
The strength of a field force changes with distance from the sourceof the field-stronger closer to the source, weaker farther away from the source. The source can be either a mass, a charged particle, or a magnetic pole.
        
             
        
        
        
Answer:
An object is said to be in motion when it changes its place with time and respect to its surrounding.

a. linear pairs, when added together, the angles will make 180 degrees, or a straight line. In this case No, for when you combine the two angles, it is not a straight line
b. False. Vertical angles make two opposite angles that are congruent
c. True. When added together, angles 1 and 4 make a straight line
d. False. As stated for question b, the two opposite angles must be congruent
hope this helps
