The correct answer is "It will be stiffer than the other".
Explanation:
If two springs have different spring constants, then the one with the larger one will be stiffer than the other. The spring constant is the amount of force required to move the spring a fixed amount of distance. The formula for the constant is given by the load divided by the distance traveled. If the load is the same, the one who travels the shortest distance will have a higher constant and be stiffer than the other.
The spring constant determines how far the spring will stretch for a given applied force: <span>F=kx→k=<span>Fx</span></span><span>. If we place the same mass on the two springs, which means we have placed the same force on them, the one that stretches </span>least<span> has the largest spring constant. Hope this helps!
