Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.
Answer:
The best point of reference is the starting position of the toy car.
Explanation:
To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.
The answers are a, igneous, and b, sedimentary. Hope this helped!

Your experiment has an accurate outcome. The only variable that should be changing is what you have already determined to be the independent variable. All other variables must be controlled (sometimes called constant) in order to preserve the accuracy of the experiment and ensure that the only thing impacted the change in the dependent variable is directly caused by the independent variable.
