A student is designing an experiment on force and motion. The student has 3 tables with the same wood surface, 3 blocks made of the same material, but different mass (100 gram, 200 gram, and 300 gram). The student is pulling the block across the table using a spring scale. What do you think the student is testing in this experiment. Type the QUESTION you think is being asked/tested in this experiment.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
