having problems staying logged in or are you experiencing issues? pleas section for solutions . anna litical and nellie newton conduct several trials in which they study the effect of varying the mass of a cart upon the acceleration of the cart when pulled with a constant force. which notebook entry accurately identifies the variables and displays the best choice for a plot? choice 1 of 4: dependent variable: acceleration independent variable: mass graph of acceleration (m/s²) vs mass (kg)

Explanation:

To determine the correct notebook entry, we analyze the experiment: the independent variable is what's manipulated (mass of the cart), and the dependent variable is what's measured (acceleration, as it depends on mass when force is constant, from Newton's second law \( F = ma \), so \( a=\frac{F}{m} \), acceleration is inversely proportional to mass). The plot has mass (independent) on the x - axis and acceleration (dependent) on the y - axis, which matches the identification of independent variable (mass) and dependent variable (acceleration) in Choice 1.

Answer:

Choice 1 of 4:
Dependent variable: Acceleration
Independent variable: Mass
(and the corresponding plot with Mass (kg) on x - axis and Acceleration (\( \text{m/s}^2 \)) on y - axis) is the correct one.
