An electric circuit is anything in which electric current flows. Typically it refers to things with wiring like the electronics in your phone, but it can be made of anything that conducts electricity.
Say you have a battery, it basically has a bunch of electrons under a potential (think of gas in a tank under pressure), but the only way for the electrons to move is to move through a conductor, which are molecules with loosely held electrons. If you take a copper wire and touch each end to the two terminals you’ve completed an electric circuit because the electrons can now flow. But you can also put things partway through the wire like a lightbulb, which when the electrons run through it generates light.

Answer:
The distance in kilometers is 4012 ×
km.
Explanation:
We know that the conversion of 1 millimeters is equal to 
meter. And then the conversion of 1 meter is equal to km. Then the conversion of 1 millimeter to km will be
1 mm = m
1 m = km
So, 1 mm = × km = km.
As here the the distance is 4012 mm, then the distance in km will be
4012 mm = 4012 × km.
So the distance is 4012 × km.
