17.[物理——选修3-3](15分)(1)(5分)在“用油膜法估测分子的大小”的实验中,下列做法正确的是。(填正确答案标号。选对1个得2分,选对2个得4分,选对3个得5分。每选错1个扣3分,最低得分为0分)A.用注射器吸取配制好的油酸酒精溶液,把它一滴一滴地滴入小量筒中,若100滴溶液的体积是1mL,则1滴溶液中含有油酸10^-2mLB.往浅盘里倒人适量的水,再将痱子粉或细石膏粉均匀地撒在水面上C.用注射器往水面上滴1滴油酸酒精溶液,同时将玻璃板放在浅盘上,并立即在玻璃板上描下油酸膜的形状D.将画有油酸膜轮廓的玻璃板放在坐标纸上,计算轮廓范围内正方形的个数,并求得油膜的面积E.根据1滴油酸溶液中油酸的体积V和油膜面积5就可以算出油膜厚度d=VS,,即油酸分子的大小

10.如图所示的电路中,电流表和电压表均为理想电表,电容器的电容C=410^-6F,定值电阻R1=1,R2=2,R3=3,R4=6,电源的电动势E=3V,内电阻r=0.75Ω,下列说法正确的是()A.开关S1闭合、S2断开时,电流表示数为0.5A,电压表示数为3VB.开关S1闭合、S2断开时,电容器的电荷量为3.210^-12CC.开关S1、S2闭合后,电流表的示数为0.4AD.开关S1闭合后,当开关S2由断开到闭合后稳定时,电容器电量的变化量为3.210^-12C

3.100卷3.如图甲所示,建筑工地经常用起重机升降建材,现以建材堆放点为原点在竖直平面内建立直角坐标系xOy,吊升某种材料的轨迹如图乙所示,该材料在水平方向的分v2,速度大小为v,,在竖直方向的分速度大小为v。材料可视为质点,下列说法正确的是D222甲A.材料一定做匀速直线运动B.材料一定做匀加速直线运动C.若材料做匀速直线运动,则vx=2vyx×vs=12yD.若材料做初速度为0的匀加速直线运动,则水平方向的分加速度大小为竖直方向分加速度大小的一半
