It is a privilege, because not everyone might have resources for training, and therefore no driving skills.
Answer:
C
Explanation:
The potential energy decreases because Magnet 1 moves against the magnetic force. If it was increased it would be kinetic
The material is called paramagnetic or non magnetic material. Opposite to this are materials whose magnetic domains are aligned and possess asmagnetism which is due to its ferrous or iron content.
There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors).
A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity.
Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.
We have the equation for electric field E = kQ/
Where k is a constant, Q is the charge of source and d is the distance from center.
In this case E is inversely proportional to
So, 
= 485 N/C
= 0.208 cm
= 0.620 cm
= ?
= 
= 53.20 N/C
