Answer:
true
Explanation:
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. ... This is called diffuse reflection. Diffuse reflection is when light hits an object and reflects in lots of different directions.
 
        
                    
             
        
        
        
Answer:
W= 4.89 KJ
Explanation:
Lets take 
temperature of hot water T₁ = 100⁰C 
T₁ = 373 K
Temperature of cold ice T₂= 0⁰C
T₂ = 273 K
The latent heat of ice LH= 334 KJ
The heat rejected by the engine Q= m .LH
Q₂= 0.04 x 334 
Q₂= 13.36 KJ
Heat gain by engine = Q₁ 
For Carnot engine


Q₁  = 18.25 KJ
The work W= Q₁  - Q₂
W= 18.25 - 13.36 KJ
W= 4.89 KJ
 
        
                    
             
        
        
        
I believe the answer in Covalent Bond.
