As the parcel of air rises, it cools. What happens to the density of the parcel when it cools? It becomes more dense, and sinks. What happens at the surface when the parcel sinks? Sinking air creates a zone of high pressure at the surface. H A. Quick (HTF)—DO NOT DISTRIBUTE

6/29/20 Angular Momentum Angular momentum of a particle Conservation of Angular momentum In an isolated system, the angular momentum of the system remains constant, no matter what changes take place within the system. A puck of mass m = 1 kg is attached to a taut cord passing through a small hole in a frictionless, horizontal surface. The puck is initially orbiting with speed v i = 466 m/s in a circle of radius r i = 6.3 x10 6 m. If the radius reduce to r i = 5.4 x10 6 m, v = 543 m/s r mv mr L 2

Analog in earth system Particle at Equator: orbiting with speed v i = 466 m/s in a circle of radius r i = 6.3 x10 6 m. Moving to 30 o north: to r i = 5.4 x10 6 m, v i = 543 m/s Stationary Observer at 30 o north: v i = 389 m/s

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
