20. A uniform plate of mass M is placed on two fast-rotating identical wheels of radius r. The coefficients of kinetic friction between the plate and both wheels are μ, the distance between the centers of the two wheels is , the wheel on the right (left) rotates counterclockwise (clockwise) with angular speed ω (see Fig. 5), and the gravitational acceleration is denoted g. If the mass center of the plate is displaced by d from the center of the two wheels, what is the frequency the plate oscillates with? (Assuming the plate is so heavy that it always stays on the wheels.)(A) ω (B) (C) (D)

19. As shown in Fig. 4, an m1 = 1.0 kg block is placed on top of an m2 = 8.0 kg block, which lies on a frictionless surface. The coefficient of kinetic friction between the two blocks is 0.20; they are connected via a pulley and a string. A hanging block of mass m3 = 6.0 kg is connected to the mass m2 block via another pulley and string. Both strings are massless and the pulleys are frictionless. What is the acceleration magnitude of the blocks? (Gravitational acceleration g =9.8 m/s²) m1 m2 M3 Figure 4. A system composed of three blocks, strings, and pulleys. (A) 3.7 m/s² (B) 2.7 m/s² (C) 9.7 m/s2 (D) 8.0 m/s²

18. The effective resistance from a to b in Fig.3 is 4.0 2.What is the resistance of individual resistors in the circuit? (The resistances of all the individual resistors are the same.) (A) 4.02(B)2.0 Ω (C) 8.0 Ω (D) 0.8 2
