there are 3 atoms in each silver sulfide
 
        
             
        
        
        
Answer:

Explanation:
The attached figure shows the whole description. Considering the applied force is 100 N. 
The acceleration of both blocks A and B, 
Firstly calculating the mass m using the second law of motion as :
F = ma
m is the mass


m = 125 kg
It suddenly encounters a surface that supplies 25.0 N a friction, F' = 25 N



So, the new acceleration of the block is  . Hence, this is the required solution.
. Hence, this is the required solution.
 
        
             
        
        
        
Atoms is basic particles ,electrons,neutrons and the Regions of the atom are called electron shells and contain the electrons. So “a neutral core surrounded by mostly empty space”sounds pretty sure to me :)
        
                    
             
        
        
        
False only some eukaryotes have cell wall like plants, fungi, and some bacteria.
        
                    
             
        
        
        
That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:
