1. You are asked to conduct an experiment on mass in motion. You are given a 100 g ball, a 100 cm long ramp with a 30° angle and three block with masses 100 g, 50 g and 25 g. Describe how you would collect data to show momentum of the 100 g ball. Identify independent and dependent variables. (10 points) I would first create a list of the independent and dependent variables

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.
