# A transverse wave pulse travels in the \(+x\)-direction along a string stretched under a tension of \(16\text{ N}\). The string has a linear mass density of \(0.25\text{ kg/m}\). The graph shows the transverse displacement \(y\) of the string as a function of position \(x\) at time \(t = 0\text{ s}\). Which of the following pairs correctly identifies the position of the pulse peak at time \(t = 0.050\text{ s}\) and the direction of velocity of the string particle located at \(x = 0.30\text{ m}\) at time \(t = 0\text{ s}\)?

A transverse wave pulse travels in the \(+x\)-direction along a string stretched under a tension of \(16\text{ N}\). The string has a linear mass density of \(0.25\text{ kg/m}\). The graph shows the transverse displacement \(y\) of the string as a function of position \(x\) at time \(t = 0\text{ s}\). Which of the following pairs correctly identifies the position of the pulse peak at time \(t = 0.050\text{ s}\) and the direction of velocity of the string particle located at \(x = 0.30\text{ m}\) at time \(t = 0\text{ s}\)?

![A 2D graph with horizontal axis labeled x (m) and vertical axis labeled y (cm). The horizontal axis ranges from 0.0 to 0.5 with major tick marks at 0.1, 0.2, 0.3, 0.4, and 0.5. The vertical axis ranges from 0 to 4 with major tick marks at 0, 2, and 4. A single smooth triangular pulse curve begins at y = 0 at x = 0.00, rises linearly to a peak of y = 4 at x = 0.20, and decreases linearly back to y = 0 at x = 0.40. The region outside 0.00 to 0.40 lies flat on the horizontal axis at y = 0. An arrow above the pulse points horizontally to the right and is labeled +v. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785826324-OJ6Bme.jpg)
