1. Un CD-ROM, que tiene un radio de 6 cm, gira a una velocidad de 2500 rpm. Calcula: a) El módulo de la velocidad angular en rad/s, b) Su frecuencia y c) el periodo.

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

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.

If anyone who can me with this hw? i would really appreciate it
