Final answer:
The question involves applying physics concepts, specifically Hooke's Law, at the high school level to determine the displacement of a cord when force is applied, using the spring constant.
Step-by-step explanation:
The subject of this question is Physics, and it falls under High School level coursework. When calculating the displacement of a cord upon the application of a force, we must consider the spring constant (k), which represents the stiffness of the springs called into question. The force needed to stretch or compress a spring can be determined using Hooke's Law, F = kx, where x is the displacement from the unstretched length, and F is the applied force. In scenario 38, a force constant of a spring is calculated based on the work done to compress the spring; this implies that the force constant can also be estimated by dividing the work (W) by the displacement squared (x2), given by W = (1/2)kx2. The details provided in the reference information don't directly solve the given problem, but they do illustrate typical approaches to solving spring constant and displacement problems that can be adapted to the scenario described in the initial question.
