The Law of the Conservation of Energy is stating that the total mechanical energy is always conserved or in simpler terms, not used or saved.
Magnetic field 'B' at a distance 'r' from an substantially
large conductor carrying current 'i' = (2x10^ -7)('i' ) / r
Magnetic field 'B' beyond the wire= (2x10^ -7)(8.15x10^18x1.6x10^ - 19 ) /0.046
=5.7 x10^ -12 tesla
As electrons move from west to east, the conventional current is from east to
west.
By means of Maxwell's right handed corkscrew rule, the way of magnetic field is
from south to north.
Answer:
Option (D)
Explanation:
Refraction is defined as the phenomenon where the light changes its course of path while travelling from one type of medium to another. This also affects the speed of the light. This process results in the formation of images by the human eyes and lenses.
This process appears to be bending of light. When a light passes from a lighter to a denser medium, it gets bend towards the normal. And when the light passes from a denser to a lighter medium then it gets bend away from the normal.
Thus, the correct answer is option (D).
The magnitude of the electric current is directly proportional to the "Electric Charge" <span>of the electric field.
Hope this helps!</span>
