2013年上海市中考物理试卷-答案
R 1与R 2两端的最大电压变化分别为：1U =15V 6V=9V △﹣，2U =12V 0V=12V △﹣，当电压表接入CD 两点间时，电压表示数的变化量最大，即U =12V 最大△。
五、实验题23.【答案】质量；玻璃板；串联；并联【解析】（1）实验室中，常用天平来测量物体的质量，测量时应将砝码放在天平的右盘内，被测物体放在左盘内，不能颠倒，这是天平自身的结构决定的；（2）在做平面镜成像特点实验时，用玻璃板代替平面镜，目的是为了确定像的位置与大小；（3）电流表属精密的测量仪器，连接时应与被测电路串联，并使电流正进负出，即电流表“+”接线柱接在电路中靠近电源正极的一端。
由于电压表与被测电路并联，故电压表应与被测电阻并联。
24.【答案】同一；35.0；5.0或10.0【解析】（1）根据凸透镜成像规律中实验的要求，首先把凸透镜、蜡烛、光屏放在光具座上，点燃蜡烛并调整蜡烛、凸透镜、光屏的高度，让烛焰、凸透镜、光屏三者中心放在同一高度上，这样才能使像成在光屏的中心；（2）由“蜡烛放置在距B 点5.0厘米处，保持透镜在A 点位置不变，移动光屏，可在光屏上得到大小不同的两个像”可知，在光屏上得到的像是实像，那么所选透镜的焦距一定不是15.0 cm 的，因为如果选择透镜的焦距为15.0 cm ，蜡烛放置在距B 点5厘米处，保持透镜在A 点位置不变，移动光屏，那么不能在光屏上得到像，而成为一束平行光；如果选择透镜的焦距为5.0 cm ，蜡烛放置在距B 点右边5.0厘米处，即蜡烛置于光具座35.0厘米刻度处时，此时u 2f ＞，保持透镜在A 点位置不变，移动光屏，在光屏上将得到倒立缩小的实像；当蜡烛放置在距B 点左边5厘米处，即蜡烛置于光具座25．0厘米刻度处时，此时u 2f ＞，保持透镜在A 点位置不变，移动光屏，在光屏上将得到倒立缩小的实像；但比蜡烛置于光具座35.0厘米刻度处时所成的像还要小；如果选择透镜的焦距为10.0 cm ，蜡烛放置在距B 点右边5厘米处，即蜡烛置于光具座35.0厘米刻度处时，此时2f u f ＞＞，保持透镜在A 点位置不变，移动光屏，在光屏上将得到倒立放大的实像；如果选择透镜的焦距为10.0 cm ，蜡烛放置在距B 点左边5.0厘米处，即蜡烛置于光具座25.0厘米刻度处时，此时u 2f ＞，保持透镜在A 点位置不变，移动光屏，在光屏上将得到倒立缩小的实像；综上所述，比较两次所成的像，当蜡烛置于光具座35.0厘米刻度处时，所成的像较大；实验中所用透镜的焦距可能是5.0或10.0厘米。

(2)如图所示,∵☉P 与☉Q 外切,∴圆心距PQ=AP+CQ=x+(13-y). ∵QM 是PB 的垂直平分线,∴BQ=PQ=y,即y=x+(13-y),又由(1)知y=25+b 22b ,则{y =x +(13-y ),y =25+x 22x ,解得{x =2513,y =9713. ∴x=2513.(3)连结EQ,∵EC=EF=4,∠EFQ=∠ECQ=90°,EQ=EQ,∴△ECQ≌△EFQ,∴∠EQC=∠EQF,又DM 为BP 的垂直平分线,则可得∠PQM=∠BQM,∴2(∠EQF+∠PQM)=180°,∴∠EQM=90°,则可知∠EQC=∠APB,又∵∠ECQ=∠PAB=90°,∴△APB∽△CQE,∴EC CQ =AB AP ,413-y =5x ,代入(1)中的y=25+x 22x, 整理之后可得13x 2-130x+125=0,解得x=65±10√2613, 检验,当x=65±10√2613时,在定义域内,∴x=65±10√2613.。
