With respect to the pivot point O, what is the magnitude of the initial angular momentum Li of the piece of clay and the final moment of inertia If of the clay-rod system? After the collisions the clay-rod system has an angular velocity w about the pivot.

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?

How to tell if a molecule is polar or nonpolar with electronegativity

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
