Answer:
arge number of electrons free to move between the charged ions in the lattice.
Explanation:
The metallic bond occurs when an atom with few electrons is united in its last level, therefore the best way to decrease the total energy of the system is to lose all its electrons to remain with the configuration of a noble gas. The electrons that it loses cannot be acquired by other atoms since they all have few electrons, thus leaving a large number of electrons free to move between the charged ions in the lattice.
Some important characteristics emerge from this description of the metallic bond:
* It has many free electrons therefore its electrical conductivity is high
* As the charged ions are fixed, the material can be malleable, bent without breaking since the free electrons create the bond that keeps the system stable.
* As the electrons are free when heating a part of the material, these electrons acquire energy and rapidly propagate it to the other side, giving a high thermal conductivity
* As the temperature increases, the electrons acquire more kinetic energy, which is why there are more collisions between them and consequently the resistivity of the material increases.
False, it does. Hope this helped!
Power in physics terms depends on both work and time because of the equation P=W/T
Hope this helps :D
Answer:
The distance between earthquake center and the measuring station is 1350 kilometers.
Explanation:
Let the earthquake center be at a distance of 'S' meters from the recording station.
Now from the basic relation of distance, speed and time we know that
For a Primary wave (P wave) let us assume that it appraoches the measuring station after 
minutes
Thus making use of the above relation we have
Now since it is given that the secondary wave (S wave) reaches the measuring spot after 2 minutes or 120 seconds thus the time taken by secondary waves to reach recorder equals 
making use of the same relation we get
Solving equation 'i' and 'ii' we get
