Answer

Cord 3 has the greatest tension, then Cord 2, and finally Cord 1 has the least amount of tension.

Work Step by Step

Tension force in this situation is strictly determined by how much weight is pulled by the cords. The greater the weight, the greater the tension. Cord 3 is pulling the most amount of weight(18kg), so it has the most tension. Cord 2 is pulling 5kg less mass(13kg), so it has less tension. Cord 1 is pulling the least mass(10kg), so it has the least tension.
