20. A uniform plate of mass M is placed on two fast-rotating identical wheels of radius r. Thecoefficients of kinetic friction between the plate and both wheels are μ, the distance between thecenters of the two wheels is f, the wheel on the right (left) rotates counterclockwise (clockwise)with angular speed w (see Fig. 5), and the gravitational acceleration is denoted g. If the masscenter of the plate is displaced by d from the center of the two wheels, what is the frequency theplate oscillates with? (Assuming the plate is so heavy that it always stays on the wheels.)edr r2wlMgFigure 5. A plate of mass M is placed on two rotating wheels making an oscillating motion.wd 2ugd(A) ω (B) (C) (D) 2µg

19. As shown in Fig. 4, an m1 = 1.0 kg block is placed on top of an m2 = 8.0 kg block, which lieson a frictionless surface. The coefficient of kinetic friction between the two blocks is 0.20; theyare connected via a pulley and a string. A hanging block of mass m3 = 6.0 kg is connected to themass m2 block via another pulley and string. Both strings are massless and the pulleys arefrictionless. What is the acceleration magnitude of the blocks? (Gravitational acceleration g =9.8 m/s²)m1m2M3Figure 4.

26. 下列何者為教育倫理的義務論主張? (A)績效 (B)尊重 (C)平衡 (D)成果

27. 實驗研究法在教育研究中經常有無法真正實驗的情形發生,例如伍老師進入學校現 場後才發現學校已經能力分班完畢,校長不肯答應重新隨機分組,隨機分派受試者 的可能便消失。伍老師只好在維持現有條件下,盡可能控制可能的誤差,找出三個 班級進行實驗,讓三個班分別接受不同的實驗教材教學。在經實驗後,研究者統計 前、後測成績,伍老師可以利用何種統計控制方法來排除前測時的差異,以看出排 除本來差異之後,是否參與實驗的三個班級之間還有明顯差異存在? (A)共變數分析(analysis of covariance) (B) T 分數或分數的常態化 (C)百分等級與百分位數 (D)次數分配(frequency distribution)及圖示法
