An object has a mass of 1 kg. When measured, it gives the following readings: 1.05 kg, 0.95 kg, 1.02 kg, 0.98 kg, 0.94 kg and 1.06 kg. What is the absolute and relative uncertainty? My teacher says that the absolute uncertainty is 0.005 but I say that it's 0.06. Which one is correct?​

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.
