Which of the following BEST matches the definition of interdependence?

Scientists conducted an experiment to show whether the ability to see an object affects a person's idea of the mass of the object. They used the following procedure: Obtain two cardboard boxes of different sizes. Place rocks in each box so that both boxes have the same mass. Close each box and tie a string to it so that participants lift each box using the string. Blindfold half of the participants in the experiment. Ask participants to lift each box using the string and report which one they think has more mass. Record results. The table shows the results of the experiment

For this assignment, you will develop several models that show how light waves and mechanical waves
are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief
description of the interaction between the wave and the material. You will also compose two typewritten
paragraphs. The first will compare and contrast light waves interacting with different materials. The
second will explain why materials with certain properties are well suited for particular functions.
