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 3 of 4:

dependent variable:	speed
independent variable:	tension

(graph: speed (m/s) on y - axis, tension (n) on x - axis, with data points showing increasing speed with increasing tension.)

Explanation:

In an experiment studying the effect of one variable on another, the independent variable is the one manipulated (tension here, as it's varied), and the dependent variable is the one measured (speed, as it depends on tension). The plot has tension (independent) on the x - axis and speed (dependent) on the y - axis, which is correct for showing the relationship. So this notebook entry correctly identifies the variables (independent: Tension, dependent: Speed) and the plot choice (tension on x, speed on y) is appropriate.

Answer:

This notebook entry is correct. The independent variable is Tension (the variable being manipulated), the dependent variable is Speed (the variable being measured as it depends on tension), and the plot has Tension (N) on the x - axis (independent variable axis) and Speed (m/s) on the y - axis (dependent variable axis), which is the proper way to display the relationship between these two variables for this study.
