On the planet xenos, an astronaut observes that a 1.59 m long pendulum has a period of 1.57 s. what is the free-fall acceleration on xenos?

Hey.. ♥️♥️ me in solving this question

Energy flows from the producer level to the level. is called

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.
