Diamonds structure is defined by series of multiple covalent bonds. Given that it is made of a very strong bond, this makes some of its bulk properties relatable to this. Example its density which is larger than most of the crystalline. Another is its intensive property of its temperature, given that the diamond is hard to break down, it also has high melting point.
It is a nuclear reaction, where the nucleus of an atom splits into smaller parts

Answer:
Work done = 13605.44
Explanation:
Data provided in the question:
For elongation of 2.1 cm (0.021 m) work done by the spring is 3.0 J
The relation between Energy (U) and the elongation (s) is given as:
U = 
................(1)
where,
k is the spring constant
on substituting the valeus in the above equation, we get
3.0 = 
or
k = 13605.44 N/m
now
for the elongation x = 2.1 + 4.1 = 6.2 cm = 0.062 m
using the equation 1, we have
U = 
or
U = 26.149 J
Also,
Work done = change in energy
or
W = 26.149 - 3.0 = 23.149 J
