Question

jack and jill are conducting an experiment to determine the effect that the angle of an inclined plane has upon the acceleration of a hot wheels car that rolls along it. which notebook entry accurately identifies the variables and displays the best choice for a plot? choice 1 of 4:
dependent variable:
angle of incline
independent variable:
acceleration
graph: acceleration (m/s²) on y - axis, angle of incline (deg) on x - axis, with data points plotted

Explanation:

To solve this, we analyze the variables and the plot:

Step 1: Identify Independent/Dependent Variables

In an experiment, the independent variable is what is manipulated (angle of incline, as Jack/Jill change it), and the dependent variable is what is measured (acceleration, as it depends on the angle).

In the given choice:

• Dependent variable is incorrectly listed as “Angle of Incline” (should be acceleration).
• Independent variable is incorrectly listed as “Acceleration” (should be angle of incline).

Step 2: Analyze the Plot

The plot has:

• X - axis: Angle of Incline (independent variable, manipulated)
• Y - axis: Acceleration (dependent variable, measured)

This plot is correct in terms of axes (X = independent, Y = dependent), but the table’s variable labels are reversed.

However, since the question asks which notebook entry (including plot) is accurate, we focus on variable identification:

• Independent Variable: Angle of Incline (plotted on X - axis, manipulated).
• Dependent Variable: Acceleration (plotted on Y - axis, measured).

The given choice’s table has the variables reversed, so it is incorrect. (Note: Since the question likely expects identifying the error or correct labeling, the key is recognizing that independent = angle, dependent = acceleration, and the plot’s axes match this relationship, but the table’s labels are wrong.)

Answer:

The given choice is incorrect because:

• Independent Variable should be “Angle of Incline” (manipulated), Dependent Variable should be “Acceleration” (measured).
• The plot’s axes (X = Angle, Y = Acceleration) are correct, but the table’s variable labels are reversed.

(If selecting the correct option, it would have:

• Dependent Variable: Acceleration
• Independent Variable: Angle of Incline
• Plot: X = Angle (independent), Y = Acceleration (dependent))
