Answer:
E = 3 × 10¹⁰ J
Explanation:
Mass, m = 100 kg
We need to find energy made by the loss of 100 kg of mass. The formula between the mass and energy is given by :
E = mc²
Where c is speed of light
Putting all the values, we get :
E = 100 kg × (3×10⁸ m/s)²
= 3 × 10¹⁰ J
So, the required energy is 3 × 10¹⁰ J.
 
        
             
        
        
        
Answer:
Static electricity is a type of energy that is produced by friction. 
Explanation:
Static electricity may be the result when there is an imbalance between the negative charges and the positive charges in the surroundings. They are non contact forces. They pull of push without actually touching the body. The charged particles interact by pulling or pushing the uncharged particles. 
These charges are released when they come closer to some uncharged or other charged particles like the electrostatic charges. It is the charge build up in an area. 
 
        
             
        
        
        
Answer:
The equation is: CuCO3(s) → CuO(s) + CO2(g) 
Explanation:
Copper carbonate decomposes at high temperatures, generating the products carbon dioxide (CO2) and copper oxide (II) CuO. In this type of decomposition reaction, a substance is broken generating two different compounds.
 
        
             
        
        
        
A mineral occurs naturally, meaning that even though there are artificial substances that might be described as mineral-like they are not minerals
