Two masses mi and m move under their mutual gravitational attraction in a uniform external gravita- tional field whose acceleration is g. choose as coordinates the cartesian coordinates x, y, z of the cen- ter ofmass vector r (taking z in the direction ofg) and the spherical coordinates r, θ and φ that define the relative vector r from mi and m2 (see hw problem set 1 for the definition of r). write down the lagrangian in terms of these 6 coordinates. calculate all 6 generalized momenta. which of these 6 momenta is conserved? write down the 6 euler-lagrange equations of motion.

Road users moving into your lane, brake lights, and abrupt changes in road surface are a. rare at night b. indicators of potential hazards c. not worth worrying about before you reach them d. no problem for experienced drivers

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
