Imagine that you live in Maine. Currently there is a high-pressure area over Maine. If a low-pressure area moves in, how will the direction of the wind change?

Asmall blob of putty of mass m falls from the ceiling and lands on the outer rim of a turntable of radius r and moment of inertia i0 that is rotating freely with angular speed ω0 about its vertical fixed-symmetry axis. (use any variable or symbol stated above as necessary.)

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
