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

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
