Sedimentary rocks are the result of igneous rocks<span> breaking down.This is a slow process so there is not as much broken down as there is not broken down.</span>
        
                    
             
        
        
        
Answer:
Explanation:
Let the charge on proton be q . 
energy gain by proton in a field having potential difference of V₀
= V₀ q 
Due to gain of energy , its kinetic energy becomes 1/2 m v₀²
where m is mass and v₀ is velocity of proton 
V₀ q = 1/2 m v₀²
In the second case , gain of energy in electrical field 
= 2 V₀q , if v be the velocity gained in the second case 
2 V₀q = 1/2 m v² 
1/2 m v² = 2 V₀q = 2 x 1/2 m v₀²
mv² = 2  m v₀²
v = √2 v₀
 
        
             
        
        
        
Each hour 430 quintillion Joules of energy from the sun hits the Earth.
In a year it is very hard to determine because of the night and different light levels. 
 
        
             
        
        
        
I can think of two of them:
-- carbon monoxide
-- black soot
        
             
        
        
        
Answer:
Δx = 1.2 m
Explanation:
The CHANGE of spring length) (Δx) can be found using PS = ½kΔx²
Δx = √(2PS/k) = √(2(450)/650) = 1.17669... ≈ 1.2 m
The actual length of the spring is unknown as it varies with material type, construction method, extension or compression, and other variables we have no clue about.
