Explanation:

To solve this, we analyze the context (likely a physics experiment on kinetic energy, where kinetic energy \( KE = \frac{1}{2}mv^2 \)).

Part I Independent Variable:

In typical kinetic energy experiments, if Part I investigates how kinetic energy changes with speed (while mass is constant), the independent variable (what’s changed) is speed. If it’s about time, but kinetic energy relates to speed/mass, speed is more likely.

Part II Independent Variable:

If Part II changes mass (keeping speed constant) to see its effect on kinetic energy, the independent variable becomes mass.

Dependent Variable (for both):

The dependent variable is what’s measured (depends on independent variable), so kinetic energy (since it depends on speed/mass).

Answer:

s (assuming standard kinetic energy experiment setup):

• In Part I, the independent variable was \(\boldsymbol{\text{speed}}\).
• In Part II, the independent variable changed to \(\boldsymbol{\text{mass}}\).
• The dependent variable for both was \(\boldsymbol{\text{kinetic energy}}\).

(Note: Exact answers depend on the experiment’s design, but this follows typical physics investigations on \( KE \) vs speed/mass.)
