Do you speak a little English cuz I can’t help you if a can’t understand you
        
             
        
        
        
It’s B. Sound travels faster through solids than liquids. Have you ever put your head on a desk, and tap the desk? That’s an example of it going faster through solids
        
                    
             
        
        
        
Answer:

Explanation:
From the question we are told that:
Height 
Time 
Generally the Newton's equation for Initial velocity upward is mathematically given by
  
  
  
Generally the velocity at  elevation and depression occurs  as ball arrives and passes through S=28
  
  
Generally the Newton's equation for time to reach initial velocity  is mathematically given by
  
  
  
  
 
        
             
        
        
        
Answer:
Increases.
Explanation:
The electric potential increases when the two positive charges of same magnitude bring close to one charge to another because there is repulsive force between them due to same charge and when the two opposite charges move away from each other, the potential energy decreases. When two opposite charges are brought closer together, electric potential energy decreases while on the other hand, when we move opposite charges apart from each other than the work done against the attractive force that leads to an increase in electric potential energy.
