In hooke’s law, what does k represent? select one of the options below as your a. mass of the spring b. length of the spring c. force of the spring d. stiffness of the spring e. width of the spring

K represents the force of the spring

I think the correct answer from the choices listed above is option D. In Hooke's law, k represents the stiffness of the spring. It is a constant that is characteristic to a spring. Also, it is the slope of the graph of force versus length. Hope this answers the question.
