Larry filled a milk carton completely with water and tightly secured the cap. he then placed it in the freezer. when he looked at the container two days later, he saw that the frozen water had expanded, breaking the container. what type of weathering is modeled by larry’s experiment?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
