Answer:
Each carbon atom is covalently bonded to four other carbon atoms in diamond. A lot of energy is needed to separate the atoms. This is because covalent bonds are strong. This is the reason why diamond has a high melting point.

Answer:
435 m
Explanation:
The precision with which the distance to the source of the earthquake can be estimated is equal to the difference in distance covered by the S- and P-waves in the time of 0.125 s.
The distance covered by each type of wave is given by
where
v is the speed of the waves
t is the time
For S-waves,
v = 3.74 km/s
t = 0.125 s
So the distance covered is
For P-waves,
v = 7.22 km/s
t = 0.125 s
So the distance covered is
So, the precision with which the distance can be determined is:
