Question

in the controlled experiment,a scientist is studying how long it takes parachutes of different sizes to fall to the ground.what are the manipulated/experimental variables?

Answer 1

In this question, two things need to be considered and they are the manipulated variable and the dependent variable. The manipulated variable is the size of the parachute taken for the experiment and the dependent variable is the time taken by the parachute to fall to the ground. I hope the answer has come to your help.

Answer 2

Answer: The size of the parachutes.

Explanation: In this experiment we have two variables: The size of the parachute and the time that the parachute needs to cover a given distance (from a plane to the ground, for example)

The only thing that the scientist can modify, the independent variable, is the size of the parachute, and this will impact in the dependent variable, the time it needs to fall to the ground.
