Answer:
3.6μF
Explanation:
The charge on the capacitor is defined by the formula 
q = CV 
because the charge will be conserved 
q₁ = C₁V₂ 
q₂ = C₂V₂ where C₂ V₂ represent the charge on the newly connected capacitor  and the voltage drop across the two capacitor will be the same 
q = q₁ + q₂ = C₁V₂ + C₂V₂
CV = CV₂ + C₂V₂
CV - CV₂ = C₂V₂
C ( V - V₂) = C₂V₂
C ( V/ V₂ - V₂ /V₂) = C₂
C₂ = 0.9 ( 10 /2) - 1) = 0.9( 5 - 1) = 3.6μF
 
        
             
        
        
        
M= Height of image/height of the object
If, M>1, then height of image>height of object.
And therefore, image is larger than the object.
        
                    
             
        
        
        
There are 3 significant figures, if that answers the question.
        
                    
             
        
        
        
Answer:mechanical waves.
Explanation:
Mechanical waves require the particles of the medium to vibrate in order for energy to be transferred. For example, water waves, earthquake/seismic waves, sound waves, and the waves that travel down a rope or spring are also mechanical waves.
