What is the mechanical work done by the initial load placed on a fiber if the fiber is linearly deformed by 3 nm? A.0 JB.3 x 10-8 JC.3 x 10-6 JD.1.5 x 10-5 J

To answer this question, we need more information. The work done on an object is calculated by the formula W = F * d * cos(θ), where W is the work done, F is the force applied, d is the distance over which the force is applied, and θ is the angle between the force and the direction of motion.

In this case, we know the distance (d = 3 nm), but we don't know the force (F) or the angle (θ). If we assume that the force is applied directly along the direction of motion (θ = 0 degrees), then the work done would be W = F * d.

Without knowing the force, we can't calculate the work done. Therefore, none of the options A, B, C, or D can be determined to be correct without additional information.
