12. [-/4 Points UCIAIS A solid, uniform disk lies on a horizontal table, free to rotate about a fixed vertical axis through its center while a constant tangential force applied to the edge exerts a torque of magnitude 1.15x10 N-m for 2.20 s. HINT (a) Calculate the magnitude of the disk's change in angular momentum (in kg-m/s). kg-m²/s (b) Find the change in the disk's angular speed (in rad/s) if its mass and radius are 0.290 kg and 0.140 m, respectively rad/s
