The angular momentum of a freely rotating disk around its center is ldisk. you toss a heavy block horizontally onto the disk along the direction shown. friction acts between the disk and the block so that eventually the block is at rest on the disk and rotates with it. we will choose the initial angular momentum of the disk to be positive. 1) what is the total, the magnitude of the angular momentum of the disk-block system

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.

Diverging mirrors and lenses always produce images

Formulating a hypothesis: part i since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of " because when writing your hypothesis
