A) the pressure in the wire
B) Young's modulus for the material of the wire
C) the tensile stress in the wire
D) the tension in the wire
E) the percent change in the length of the wire

Quizplus · Accepted Answer

The slope of this graph represents the Young's modulus for the material of the wire, which is a measure of the wire's stiffness and its resistance to deformation. It is calculated as the ratio of stress to strain, which is the slope of the graph.
