DENSITY Learning Objectives After completing this Lecture Tutorial, students should be able to: explain how density is different than weight. apply the concepts of density to explain plate movement at convergent boundaries. Part 1: Comprehension of Density Density is the amount of material in a given volume. It can be thought of as how compact something is. If two objects are the same size but one is heavier, it is more dense. 1. For each of the three rows below, circle which is more dense. One row will have the same density. a bucket of ping pong balls or a bucket of golf balls or There are the same density. or There are the same density. a small piece of granite or a large piece of granite or There are the same density. 2. Three students are discussing the density of different sized rocks. Student 1: I think a small rock is less dense than a large one. When you pick them up, the small rock is much lighter than the big rock. Since density is the same thing as weight, a heavier rock is…

Please help with number 6 I got a negative number could that be right?

5. Find x if x² (0.0010-x) 1.8 x 10-4
