Question

2 a scientist tests if speed affects the number of bugs smashed on a windshield while traveling on a highway. what is the independent variable? a the speed of the car b the type of bugs found on the car c the highway the car travels on d the number of bugs on the windshield

Explanation:

To determine the independent variable, we recall that the independent variable is the one that is manipulated or changed to observe its effect on another variable (the dependent variable). In this experiment, the scientist is testing how speed affects the number of bugs smashed. So, the speed of the car is the variable being manipulated (independent variable), while the number of bugs smashed is the dependent variable (affected by speed). Option B (type of bugs) and C (highway) are not the focus of the test, and D is the dependent variable.

Answer:

A. The speed of the car
