(1)如图甲所示,先用多用电表“×1”挡粗测其电阻为然后用图乙所示的螺旋测微器测得其直径为20097mm,再再用图丙所示的毫米刻度尺测得其长度为为10.20cm.2+9.7×0.01=2.097

9.如图所示,在M、N两点固定带电荷量分别为+Q和-q(Q>q)的点电荷,以M连线的中点O为圆心的圆周上有A、B、C,D四点。下列判断正确的是A.A点的电场强度大于B点的电场强度B.C点的电场强度方向与D点的电场强度方向相同C.A、C两点间的电势差等于A、D两点间的电势差D.试探电荷一q在A点的电势能大于在B点的电势能

某兴趣小组对老师演示惯性的一个实验进行了深入的研究。如图甲所示,长方形硬纸板放在水平桌面上,纸板一端稍稍伸出桌外,将一块橡皮擦置于纸板的中间,用手指将纸板水平弹出,如果弹的力度合适,橡皮擦将脱离纸板,已知橡皮擦可视为质点,质量为m1=20g,硬纸板的质量为m2=10g,,长度为l=5cm。,橡皮擦与纸板、桌面间的动摩擦因数均为u1=0.2,纸板与桌面间的动摩擦因数为u2=0.3,,认为最大静摩擦力等于滑动摩擦力,重力加速度为g。(1)手指对纸板的作用时间很短,可认为作用结束后,纸板获得速度v0但位移近似为零,则要使橡皮擦脱离纸板,v0需满足的条件?(2)若要求橡皮擦移动的时间不超过o=0.2s,,求纸板被弹出的最小速度?
