calculate the magnitude of the polarisation for a dielectric material in an electric field of 10^6 V/m, given that the susceptibility of the material is 4.38

What is the unit of electric charge in the MKS system?

A ball hits a wall horizontally at 6m/s, it rebounds horizontally at 4.4 m/s, the ball is in contact with the wall for 0.04s, what is the acceleration?

I am trying to figure out an important puzzle/riddle.

What am I describing?

Iron ingots set like bricks in a wall/barrier formation.
Between the ingots is burning wood and coal.
Molten copper is poured over this structure filling the gaps between the iron ingots.
Finally the barrier solidifies as a solid object. Iron ingots using copper as the mortar between the ingots.

What would be the abilities of a barrier with such a construction?
