In what direction and how fast (in mm/y) is the Frodo Continent moving relative to the Galadriel Islands? Show your equations and explain where each number came from. Hint: Assign positive and negative signs to the different directions of motion. Specific suggestion: make all plate motion to the right (east) have positive velocities and make all plate motion to the left (west) have negative velocities.

Avalue that describes how heavy an object is and is related to the force of gravity is

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.

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?
