Answer:
True
Explanation:
Nonrenewable resources ARE limited in supply. They don't get replaced at the speed they get made. For example: we pump crude oil from the ground at a rate that makes it impossible for crude oil to be replaced. Crude oil takes millions of years to produce
 
        
             
        
        
        
12. The answer would be C. 1.50 s. This is because if you divide 60 by 40, you will get 1.5.
13. For this one I'm not sure, but what I can tell you is that the heavier something is the faster it will sink, the lighter it is, it will float. 
 
        
             
        
        
        
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
 
        
             
        
        
        
Answer:
If you mean Lewis dot diagrams, aka electron-dot diagrams, then these are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.
