2011届高考第一轮总复习满分练兵场
2011届高考第一轮总复习满分练兵场一、选择题1．如图甲、乙、丙中，除导体棒ab 可动外，其余部分均固定不动，甲图中的电容器C 原来不带电．设导体棒、导轨和直流电源的电阻均可忽略，导体棒和导轨间的摩擦也不计，图中装置均在水平面内，且都处于方向垂直水平面(即纸面)向下的匀强磁场中，导轨足够长．现给导体棒ab 一个向右的初速度v 0，在甲、乙、丙三种情形下导体棒ab 的最终运动状态是 ( )A ．三种情形下导体棒ab 最终都做匀速运动B ．甲、丙中，ab 棒最终将以不同速度做匀速运动；乙中，ab 棒最终静止C ．甲、丙中，ab 棒最终将以相同速度做匀速运动；乙中，ab 棒最终静止D ．三种情形下导体棒ab 最终都静止 [答案] B[解析] 甲图中ab 棒运动后给电容器充电，当充电完成后，棒以一个小于v 0的速度向右匀速运动．乙图中构成了回路，最终棒的动能完全转化为电热，棒停止运动．丙图中棒先向右减速为零，然后反向加速至匀速．故正确选项为B.2．长为4L 的粗细均匀的金属杆围成一个正方形闭合框架，框架放在光滑的水平桌面上，另一根长为L 的同种材料、同样粗细的金属杆搁在其上，如图所示．匀强磁场垂直穿过框架平面，不计一切摩擦．当直杆ab 获得一个初速度沿框架从左向右运动的过程中( )A ．任一时刻ab 杆的加速度大小均是框架加速度大小的4倍B ．任一时刻ab 杆的加速度方向均和框架的加速度方向相同C ．ab 杆对地做匀减速运动，框架对地做匀加速运动D ．任一时刻ab 杆的发热功率均是框架发热功率的14[答案] A[解析] 任一时刻ab 和框架所受的安培力大小相等、方向相反，由于ab 质量只有框架质量的1/4，故ab 杆的加速度大小是框架加速度大小的4倍，A 正确，B 错误．由于安培力大小变化，ab 杆和框架的加速度是变化的，C 错．ab 杆在框架上滑动时，框架的等效电阻不断变化，D 错误．3．如图所示，闭合金属线框从一定高度自由下落进入匀强磁场中，磁场足够大，从ab 边开始进入磁场到cd 边刚进入磁场的这段时间内，线框运动的速度—时间图象不可能是( )[答案] B[解析] 当ab 边刚进入磁场时，若线框所受安培力等于重力，则线框在从ab 边开始进入磁场到cd 边刚进入磁场前做匀速运动，故A 是可能的；当ab 边刚进入磁场时，若线框所受安培力小于重力，则线框做加速度逐渐减小的加速运动，最后可能做匀速运动，故C 情况也可能；当ab 边刚进入磁场时，若线框所受安培力大于重力，则线框做加速度逐渐减小的减速运动，最后可能做匀速运动，故D 可能；线框在磁场中不可能做匀变速运动，故B 项是不可能的，应选B.4．(2009·浙江台州)如图所示，两光滑平行导轨水平放置在匀强磁场中，磁场垂直导轨所在平面，金属棒ab 可沿导轨自由滑动，导轨一端跨接一个定值电阻R ，导轨电阻不计．现将金属棒沿导轨由静止向右拉，若保持拉力F 恒定，经时间t 1后速度为v ，加速度为a 1，最终以速度2v 做匀速运动；若保持拉力的功率P 恒定，棒由静止经时间t 2后速度为v ，加速度为a 2，最终也以速度2v 做匀速运动，则 ( )A ．t 2＝t 1B ．t 1>t 2C ．a 2＝2a 1D ．a 2＝3a 1 [答案] BD[解析] 若保持拉力F 恒定，在t 1时刻，棒ab 切割磁感线产生的感应电动势为E ＝BL v ，其所受安培力F B ＝BIL ＝B 2L 2v R ，由牛顿第二定律，有F －B 2L 2v R ＝ma 1；由题意，棒最终以2v 做匀速运动，则F ＝2B 2L 2v R ，故a 1＝B 2L 2v mR.若保持拉力的功率P 恒定，在t 2时刻，有P v －B 2L 2v R ＝ma 2；棒最终也以2v 做匀速运动，则P 2v ＝2B 2L 2vR ，故a 2＝3B 2L 2v mR＝3a 1，选项D 正确，C 错误；由以上分析可知，在瞬时速度相同的情况下，恒力F 作用时棒产生的加速度比拉力的功率P 恒定时产生的加速度小，故t 1>t 2，选项B 正确，A 错误．5．如图所示，一个边长为a 、电阻为R 的等边三角形线框，在外力作用下，以速度v 匀速穿过宽均为a 的两个匀强磁场．这两个磁场的磁感应强度大小相等，方向相反．线框的运动方向与底边平行且与磁场边缘垂直，取逆时针方向的电流为正．若从图示位置开始计时，关于线框中产生的感应电流i 与运动时间t 之间的函数图象，正确的是 ( )[答案] A[解析] 根据楞次定律，电流应先为逆时针，故B 错；当线框同时在两个磁场中切割磁感线的时候，形成同向电流，所以峰值应为谷值的一半，C 错；根据公式ε＝BL v sin θ可知ε∝L ，故图象应为分段线性函数，故A 正确，D 错误．6．(2010·浙江省部分重点中学联考)如图a 所示，在光滑水平面上用恒力F 拉质量为m 的单匝均匀正方形铜线框，边长为a ，在1位置以速度v 0进入磁感应强度为B 的匀强磁场并开始计时t ＝0，若磁场的宽度为b (b >3a )，在3t 0时刻线框到达2位置速度又为v 0并开始离开匀强磁场．此过程中v －t 图象如图b 所示，则 ( )A ．t ＝0时，线框右侧边MN 的两端电压为Ba v 0B ．在t 0时刻线框的速度为v 0－Ft 0mC ．线框完全离开磁场的瞬间(位置3)的速度一定比t 0时刻线框的速度大D ．线框从进入磁场(位置1)到完全离开磁场(位置3)的过程中产生的电热为2Fb [答案] D[解析] t ＝0时，线框右侧边MN 的两端电压为外电压，为34Ba v 0，A 项错误；从t 0时刻至3t 0时刻线框做匀加速运动，加速度为F m ，故在t 0时刻的速度为v 0－2at 0＝v 0－2Ft 0m，B 项错误；因为t ＝0时刻和t ＝3t 0时刻线框的速度相等，进入磁场和穿出磁场的过程中受力情况相同，故在位置3时的速度与t 0时刻的速度相等，C 项错误；线框在位置1和位置3时的速度相等，根据动能定理，外力做的功等于克服安培力做的功，即有Fb ＝Q ，所以线框穿过磁场的整个过程中，产生的电热为2Fb ，D 项正确．7．如图所示，相距为d 的两条水平虚线L 1、L 2之间是方向水平向里的匀强磁场，磁感应强度为B ，质量为m 、电阻为R 的正方形线圈abcd 边长为L (L <d )，将线圈在磁场上方高h 处由静止释放，cd 边刚进入磁场时速度为v 0，cd 边刚离开磁场时速度也为v 0，则线圈穿越磁场的过程中(从cd 边刚入磁场一直到ab 边刚离开磁场) ( )A ．感应电流做功为mglB ．感应电流做功为2mgdC ．线圈的最小速度可能为mgRB 2L 2D ．线圈的最小速度一定为2g (h ＋L －d ) [答案] BCD[解析] 根据cd 边刚进入磁场和cd 边刚离开磁场时速度大小相等，对这一过程应用动能定理可得线圈进入磁场的过程克服安培力做功为mgd ，出磁场的过程同样要克服安培力做功mgd ，所以总共产生电能2mgd ，则感应电流做功2mgd ，所以A 错误、B 正确；若进入过程中出现匀速运动情况，则安培力与重力相等⎝⎛⎭⎫mg ＝B 2L 2v min R ，所以存在最小速度为mgRB 2L2的可能，C 正确；对整个过程应用动能定理可得D 正确．8．如图所示，ab 、cd 是固定在竖直平面内的足够长的金属框架．除bc 段电阻为R ，其余电阻均不计，ef 是一条不计电阻的金属杆，杆两端与ab 和cd 接触良好且能无摩擦下滑，下滑时ef 始终处于水平位置，整个装置处于垂直框面的匀强磁场中，ef 从静止下滑，经过一段时间后闭合开关S ，则在闭合S 后 ( )A ．ef 的加速度可能大于gB ．闭合S 的时刻不同，ef 的最终速度也不同C ．闭合S 的时刻不同，ef 最终匀速运动时电流的功率也不同D ．ef 匀速下滑时，减少的机械能等于电路消耗的电能 [答案] AD[解析] 闭合前，ef 自由落体，到闭合时，设瞬时速度为v ，此时ef 所受安培力F 安＝B 2l 2vR，F 安可能出现大于2mg的情况，故A 正确．不同时刻闭合S ，可能会出现三种情况：(1)F 安＝mg 时，ef 正好从此时匀速运动，速度v ＝mgRB 2l2(2)F 安<mg 时，ef 加速至F 安＝mg 后再匀速运动，此时速度v ＝mgRB 2l 2(3)F 安>mg 时，ef 减速至F 安＝mg 后再匀速运动，此时速度v ＝mgRB 2l2.所以最终速度v ＝mgR B 2l 2及最大功率P ＝E 2R ＝B 2l 2v2R与S 闭合时刻无关．匀速下滑时重力势能→电能→内能．所以应选A 、D.二、非选择题9．由于国际空间站的运行轨道上各处的地磁场强弱及方向均有所不同，所以在运行过程中，穿过其外壳的地磁场的磁通量将不断变化，这样将会导致________现象发生，从而消耗国际空间站的能量．为了减少这类消耗，国际空间站的外壳材料的电阻率应尽可能________(填“大”或“小”)一些．[答案] 电磁感应 大[解析] 电阻率较大，电阻也较大，同样的电磁感应现象，产生的电动势一定，由P ＝U 2R可知，电阻较大时，消耗的电功率较小，可以减少能量消耗．10．(2009·合肥市一模)如图所示，光滑的金属导轨间距为L ，导轨平面与水平面成α角，导轨下端接有阻值为R 的电阻，质量为m 的金属细杆ab 与绝缘轻质弹簧相连静止在导轨上，弹簧劲度系数为k ，上端固定，弹簧与导轨平面平行，整个装置处在垂直于导轨平面斜向上的匀强磁场中，磁感应强度为B .现给杆一沿导轨向下的初速度v 0，杆向下运动至速度为零后，再沿导轨平面向上运动达最大速度，大小为v 1，然后减速为零，再沿导轨平面向下运动……一直往复运动到静止(导轨与金属细杆的电阻忽略不计)．试求：(1)细杆获得初速度瞬间，通过R 的电流大小； (2)当杆速度为v 1时离最初静止时位置的距离L 1；(3)杆由初速度v 0开始运动直到最后静止，电阻R 上产生的焦耳热Q .[答案] (1)BL v 0R (2)B 2L 2v 1kR (3)12m v 20[解析] (1)由E ＝BL v 0；I 0＝ER 可得I 0＝BL v 0R.(2)设杆最初静止不动时弹簧伸长x 0，kx 0＝mg sin α当杆的速度为v 1时弹簧伸长x 1，kx 1＝mg sin α＋BI 1L此时I 1＝BL v 1R ，L 1＝x 1－x 0 得L 1＝B 2L 2v 1kR.(3)杆最后静止时，杆在初始位置，由能量守恒可得Q ＝12m v 2011．(2010·潍坊)如图甲所示，平行金属导轨竖直放置，导轨间距为L ＝1m ，上端接有电阻R 1＝3Ω，下端接有电阻R 2＝6Ω，虚线OO ′下方是垂直于导轨平面的匀强磁场．现将质量m ＝0.1kg 、电阻不计的金属杆ab ，从OO ′上方某处垂直导轨由静止释放，杆下落0.2m 过程中始终与导轨保持良好接触，加速度a 与下落距离h 的关系图象如图乙所示．求：(1)磁感应强度B ；(2)杆下落0.2m 过程中通过电阻R 2的电荷量q .
