A. Because metal is a good conductor of heat.
If a frying pan wasn't a good conductor of heat it's purpose of cooking things wouldn't really be resolved. Without heat it couldn't cook well. I think lol that's my way of thinking.
Hope I helped :)
        
                    
             
        
        
        
The only evidence you have that you exist as a self-aware being is your conscious experience of thinking about your existence. Beyond that you're on your own. You cannot access anyone else's conscious thoughts, so you will never know if they are self-aware.
        
             
        
        
        
Answer:
a)   C = 4,012 10⁻¹⁴ F, b)  Q = 1.6 10⁻¹¹ C
, c)   U = 3.21 10⁻¹¹ J
Explanation:
a) The capacitance of a capacitor is
        C = k e₀ A / d
Let's calculate
        C = 4 8.85 10⁻¹² 17 10⁻⁴ / 0.150 10⁻²
        C = 4,012 10⁻¹⁴ F
b) let's look  the charge
         C = Q / ΔV
          Q = C ΔV
          Q = 4,012 10⁻¹⁴ 400
          Q = 1.6 10⁻¹¹ C
c) The stored energy
         U = ½ C ΔV²
         U = ½ 4,012 10⁻¹⁴  400²
         U = 3.21 10⁻¹¹ J
 
        
             
        
        
        
since centripetal acceleration is always towards the center of the circle
so at the given position where speed and acceleration is given the center coordinate will be towards the center of circle
also we know that



so the coordinates of the center will be


so the coordinate is (3.20 m, 4.04 m)
