The discussion centers on the absence of the point (0, -3) in the initial graph of a traveling sinusoidal wave. Participants question why this point was not included and why a y versus time graph was not utilized. Clarifications are sought regarding the significance of units in the context of the problem. The conversation highlights the importance of understanding the wave equation and its parameters. Ultimately, the initial omission of (0, -3) raises questions about the completeness of the graph representation.
The answer is (B) but I don't really understand why.
Based on formula of Young Modulus:
$$x=\frac{FL}{AE}$$
The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A##
I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
