In an experiment to find out how the height from which a student drops a ball affects how high the ball bounces, the independent variable is the ___ * **What is changed?

Question 2 options:

A)

force acting on the ball

B)

height from which the ball is dropped

C)

height the ball bounces

D)

diameter of the ball

B and D

Explanation:

While doing this experiment, the variable that you can change it's the height from here you drop it and if the analysis pretend to establish the relation between diameter and bouncing, it can be the diameter

The independent variable is the height from which the ball is dropped.

for the second part what is changed is the Height from which the ball is dropped (B)

Explanation:

An independent variable is a factor that is completely subject to the control of the scientist, that is the variable which the scientist can change at will. In this case, the independent variable is the height from which the ball is dropped because the student will drop the ball from different heights pre-determined by him, inorder to study and record the effect of how it affects the height to which the ball bounces, which then becomes the dependent variable.

so the height is changed.
