9.如图所示,半圆形玻璃砖的圆心为O、半径为R,折射率n=2.一束单色光从C点垂直ABn=2。C面入射后,恰好在玻璃砖圆形表面发生全反射;当入射角为a时,光束折射后恰好能到达S点,α已知真空中的光速为,则A.OC间的距离为B.入射角=60^C.光束从C点传播到S点用时5cRRRcD.若用该单色光垂直照射整个AB面,则透光弧长为为R3

9.如图所示,间距为L的固定平行双轨道由足够长的水平光滑段和倾角为0的粗糙段构成,所在空间存在与导轨所在平面垂直、磁感应强度大小为B的匀弧磁场,质量均为m、电阻均为R的金属棒ab、cd垂直放在水平、倾斜导轨上且与导轨接触良好,起初cd桦恰好静止。现在ab棒在水平向右的恒力F作用下从静止开始向右加速,当ab棒达到最大速度时,d棉又恰好能静止;导轨的电阻不计,最大静摩擦力等于滑动摩擦力,重力加速度大小为g,下列说法正确的是A.cd棒与倾斜导轨间的动摩擦因数为sinθB.ab棒的最大加速度为1gsinθC.ab棒的最大速度为4mgRB^2L^2D.恒力F的最大功率为8m^2g^2R^2B^2L^2
