Question

omars class is learning about circuits in science class this week. his teacher explained that a circuit must be a closed loop to allow the current to flow.
which of the following is an example of a real - life closed loop?
race car track
ladder
horseshoe
street

Explanation:

A closed loop is a continuous, circular - like path. A race car track is a continuous loop where a car can go around and around without having to stop and reverse direction to continue moving in the same general circular path. A ladder is a linear structure with rungs (not a loop). A horseshoe is a U - shaped (open at one end) object. A street is usually a linear path (even if it has curves, it is not a complete loop in the sense of a circuit's closed loop analogy).

Answer:

race car track
