(2)在“用单摆测定重力加速度”的实验中,实验装置如图甲所示。①先用游标卡尺(50分度)测量摆球的直径,如图乙所示,摆球直径为cm。②(单选)下列操作正确的是A.摆长应为绳长和摆球直径之和B.为使实验效果明显一点,摆球的初始摆角可以达到30^C.若实验中有直径相同的铁球与木球,应选择铁球作为摆球D.测量周期时,应从摆球经过最高点开始计时,这样摆球速度小,时间测量更精确

8.如图所示,半径R=1.2m的半球形碗固定于水平面上,碗口水平且AB为直径,O点R=1.2mv1为碗的球心。将一弹性小球(可视为质点)从A点沿AB方向以速度v水平抛出,小球与碗内壁碰撞一次后恰好经过B点;若将该小球在AB直径上离(32R处的C点沿CB方向以速度v2水平抛出,小球与碗内壁碰撞一次后恰好返回C点。假设小v2球与碗内壁碰撞前、后瞬间小球沿切线方向的速度不变,沿法线方向的速度等大反向,重力加速度g=10m/s^2,则A.3m/s,6m/sB.3m/s,3m/sC.6m/s,6m/sD.6m/s,3m/s

则磨石受到的摩擦力大小为4.如图所示,某中学新校区装修时,工人用质量为m的磨石对斜壁进行打磨,当对磨石施加方向竖直向上、大小为F的推力时,磨石恰好沿斜壁向上匀速运动,已知磨石与斜壁之间的动摩擦因数为A.(F-mg)cosθB.(F-mg)sinθC.(F-mg)cosθD.(F-mg).
