Answer:
4.68227 °C
Explanation:
 = Mass of object = 500 kg
 = Mass of object = 500 kg
 = Mass of water = 25 kg
 = Mass of water = 25 kg
c = Specific heat of water at 20°C = 4186 J/kg°C
h = Height from which the object falls = 100 m
g = Acceleration due to gravity = 9.8 m/s²
The potential energy and heat will balance each other

The temperature change in the water is 4.68227 °C
 
        
             
        
        
        
The charge of the copper nucleus is 29 times the charge of one proton:

the charge of the electron is

and their separation is

The magnitude of the electrostatic force between them is given by:

where 

 is the Coulomb's constant. If we substitute the numbers, we find (we can ignore the negative sign of the electron charge, since we are interested only in the magnitude of the force)
