Question

stan dingwaives and anna conda are conducting a study of the effect of varying tension in a wire upon the speed of wave traveling through the wire. which notebook entry accurately identifies the variables and displays the best choice for a plot? choice 2 of 4: dependent variable: tension independent variable: speed graph with speed (m/s) on y - axis, tension (n) on x - axis, data points

Explanation:

In an experiment studying the effect of tension on wave speed, the independent variable (the one manipulated) is tension, and the dependent variable (the one measured/affected) is speed. Here, the notebook entry incorrectly swaps them: dependent should be speed, independent should be tension. The plot has tension (N) on the x - axis (independent variable's axis) and speed (m/s) on the y - axis (dependent variable's axis), which is correct for the plot, but the variable labels in the table are wrong. So this notebook entry does not accurately identify the variables (even though the plot axes are correct for the correct variable roles).

Answer:

This notebook entry does not accurately identify the variables (incorrectly swaps dependent and independent variables: dependent should be speed, independent should be tension; though the plot axes are correct for the correct variable roles).
