Can you solve these physics riddles? ft Simone Giertz - Part 1/3

The force due to air resistance should be greater on the heavier ball (once they've both reached terminal velocity). The heavier ball experiences a force m1g due to gravity (where m1 is the mass of the heavier ball), and the lighter ball experiences a force m2g due to gravity  (where m2 is the mass of the lighter ball). For the balls to move at constant velocity, the definition of terminal velocity,  they each must experience an equal and opposite force due to air resistance. So ball 1 experiences m1g due to the air and ball 2 experiences m2g. Since g, the acceleration due to gravity,  is constant for both, the heavier ball experiences a greater force due to air resistance since m1>m2.
