Use the formula B(at the center)= (4 pi * 10^(-7) ) * I (current) / ( 2 radius)
and you will get the answer that will be 6.
There is no chart provided in this statement. However, the current that flows within an electrically charged item is dependent on how it is arranged. There are two kinds of current and these are, parallel and circuit currents. Current that flows in parallel current is less than when it is farther away from the electric source; current that flows in a series current flows at a constant rate regardless of how far it is from the electrical source.
B they belong to the same family of elements
The answer would be B.
Semantics means the study of words and their meanings.
Hope this helped!
