1_山东卷(解析) ——2022年普通高中学业水平等级考试

山东省2022年普通高中学业水平等级考试B由衰变规律可知,经过n个半衰期剩余碘125的质量m余=12nm0,n=18060=3,故m余m0=18,B正确㊂A火箭先向上做加速度逐渐减小的变加速直线运动,加速度为零时速度最大,则动能最大,故A正确;火箭受到重力㊁高压气体的推力和空气阻力的作用,火箭所受合力的冲量等于其动量的增量,合力做的功等于其动能的增加量,C㊁D均错误;高压气体释放的能量只有一部分转化为火箭的动能,B错误㊂C将取走的A㊁B处圆弧上的电荷补回去,由对称性和微元法可知,整个带电圆环在O点产生电场的合场强等于零,由此可知,剩余部分带电环上的电荷与A㊁B处带电圆弧上的电荷产生的电场等大反向,由点电荷的场强公式㊁电场的叠加规律和几何关系可得,A㊁B处带电圆弧上的电荷产生的电场在O点的合场强E1=kqAR2,方向由O指向C,由题意可知,qA=Q2πRΔL,D处的点电荷q在O点产生电场的场强与E1等大同向即可,故q应为负电荷,由kq(2R)2=kQ㊃ΔLR2㊃2πR,解得q=2QΔLπR,故C正确㊂D由单匝线圈所接电压表的读数有:n11=2200.1,则n1=2200,另外Um=2202V,故A错误;由n1nBC=U1UBC和U2BCR=P代入数据解得,UBC=12V,nBC=120,则I=UBCR=1A,故B错误;由ω=2πf=100πrad/s,得f=50Hz,T=1f=0.02s,故C错误;R接在AC两端时,I=UACR=3012A=2.5A,故D正确㊂C设活塞质量为m,大气压强为p0,左图中缸内气体压强为p1,右图中缸内气体压强为p2,活塞的横截面积为S,则p1S=mg+p0S,即p1=mgS+p0,p2S=p0S,即p2=p0,因此在该过程中气体压强变小,体积增大,气体膨胀对外做功,则外界对气体做的功W<0,由于是绝热容器,即Q=0,根据热力学第一定律ΔU=Q+W可知ΔU<0,即理想气体内能减小,气体温度降低,选项A错误;理想气体的温度降低,分子平均动能减小,但并不是所有气体分子的运动速率都会减小,选项B错误;根据理想气体的分子运动速率分布规律,当温度降低时,速率大的分子占比将会减小,选项C正确,D错误㊂技巧点拨㊀分析封闭的气体的压强问题时,常常需要对活塞受力分析,利用平衡条件分析,进而分析封闭的气体的压强㊂C根据题意,卫星绕地球的周期t=Tn,设地球质量为M,地心与卫星中心距离为r,卫星绕地球做匀速圆周运动,根据万有引力提供向心力可知GMmr2=mr2πtæèçöø÷2,则GM=r32πT/næèçöø÷2,且GM=gR2,h=r-R,代入化简得h=3gR2T24π2n2-R,故选C㊂Aa光的全反射临界角C1满足sinC1=11.42<22,即C1<45ʎ,b光的全反射临界角C2满足sinC2=11.40>22,即C2>45ʎ㊂当光线垂直AB射入之后,部分光路如图,光在介质中OC界面的入射角为45ʎ,则a光发生全反射,b光既有折射又有反射㊂当入射点从A向B移动时,经OC面反射后的光线,在PM上的入射点从Q向P移动,根据几何关系可知,入射角从Q处的0ʎ一直增大81到P处的45ʎ,所以b光不会发生全反射,a光会在P点发生全反射,恰好从M射出,故选项A正确㊂B根据a=v2r可知,在BC段㊁CD段的最大速率分别为vBC=a1r1=6m/s,vCD=a2r2=2m/s,在BC段㊁CD段的速率不变,因此在两圆弧段运动的最大速率v=2m/s,通过两圆弧的时间为t2=πr1v+πr2v=7π2s,小车从A点以最大速率v0=4m/s匀速经过一段距离l之后开始减速,恰好到B点时速率为2m/s,根据匀变速直线运动规律得v2-v20=-2a1(8m-l),解得l=5m,在AB段经历时间t1=lv0+v-v0-a1=94s,因此总时间为t=94+7π2æèçöø÷s,选项B正确㊂易错提醒㊀通过固定圆弧的时间,取决于沿圆弧运动的速率,BC和CD两段圆弧半径不同,但通过的速率相等,因此必须先要找出符合题意的最大速率㊂在AB段运动的最短时间的对应条件是整个阶段的平均速度最大,因此必须先以最大速度做匀速直线运动,然后匀减速运动到B点㊂AC因为t=0时位于原点O的质点在正向最大位移一半的位置,故该质点的振动方程为y=20sin2πT㊃t+π6æèçöø÷cm,由图得T=12s,故t=7s时该质点的位置y7=20sin2π12ˑ7+π6æèçöø÷cm=-103cm,因该简谐波传播方向未知,故选A㊁C项㊂ACD图乙是干涉图样,在发生干涉时也有衍射,故A正确㊂遮住一条缝时是单缝衍射,若狭缝变宽,则图丙中亮条纹宽度变小,故B错误㊂由Δx=Ldλ知,增大L时,Δx变大,故C正确㊂屏上P点到双缝的路程差满足Δx=(2n+1)λ2(n=0,1,2,3 )时,P点处一定是暗条纹,D正确㊂BD网球击中墙壁时,竖直速度减为零,故击出时vy=2g(H-h)=12m/s,t上=vyg=1.2s,击出时vx=v20-v2y=5m/s,水平位移x=vxt=6m,故图示中θ=37ʎ,网球击中墙壁前瞬间,在垂直墙面方向上的速度分量vxʅ=vxcosθ=4m/s,在平行墙面方向上的速度分量vxʊ=vxsinθ=3m/s,碰墙后vxʅᶄ=0.75vxʅ=3m/s,故碰墙后速度为v=v2xʊ+vxʅᶄ2=32m/s,撞墙后着地点到墙壁的距离为d=vxʅᶄ㊃2Hg=3.9m,故B㊁D正确㊂BC在t=0至t=π2ω的过程中,l有先变大后变小,故E先增大后减小,故B正确,A错误㊂在t=0至t=π4ω的过程中,有效切割长度l有=Lcosωt,E=12Bl2有ω=BL2ω2cos2ωt,由三角函数求导知识可得,E的变化率ΔEΔt=BL2ω2㊃sinωtcos3ωt变大,故C正确,D错误㊂易错点拨㊀从t=0至t=变大,E的变化率需要对答案(1)12㊀(2)0.20㊀(3)0.13解析(1)由F-t图像可知,弹簧伸长5.00cm时弹力91F=0.610N,则k=Fx=0.6100.05N/mʈ12N/m㊂(2)由牛顿第二定律可知a=Fm,图线的斜率k=1m,由丙图中图线Ⅰ的斜率可求得mʈ0.20kg㊂(3)由丙图中图线Ⅱ的斜率可求得mᶄʈ0.33kg,则待测物体的质量mᵡ=mᶄ-m=0.13kg㊂答案(1)A1㊀60㊀(2)100㊀(3)无解析(1)回路中的电流I<ER0=10mA,即不可能使A2半偏,故选用的电流表为A1;当A1半偏时,回路中的电流I=5mA,若不考虑电池内阻,有I=ER0+RA1+R,代入数据解得此时滑动变阻器接入电路的阻值R=60Ω㊂(2)电流表指针指在满刻度的35处,此时回路中的电流Iᶄ=6mA,由Iᶄ=ERx+RA1+R,解得Rx=100Ω㊂(3)若考虑电池内阻,则I=ER0+RA1+R+r,Iᶄ=ERx+RA1+R+r,其中RA1+R+r不变,故未考虑电池内阻,对Rx的测量值无影响㊂答案(1)MmaρgV㊀(2)p0+ρgH1p0+ρgHm解析(1)鱼静止在水面下H处时,重力与浮力平衡,此时B室气体压强不变,仍等于外界压强,气体密度不变,B室体积增加部分所受浮力即为鱼所受的合外力,故有ρgΔV=Ma则充入B室的气体质量Δm=mVΔV=MmaρgV(2)鱼静止于水面下H处时,B室内气体压强p=p0+ρgH鱼静止于水面下H1处时,B室内气体压强p1=p0+ρgH1静止时B室体积不变,仍为V,气体温度不变,压强改变,为变质量问题㊂设从静止于H处变为静止于H1处时需要往B室充入p压强下ΔVᶄ体积的气体,由玻意耳定律,有p(V+ΔVᶄ)=p1V则ΔVᶄ=p1-ppV,且m1-mm=ΔVᶄV可得m1m=p1p解得:m1=p0+ρgH1p0+ρgHm答案(1)0.1㊀(2)0.36m解析(1)电动机输出功率P输=UI-I2RP输=F拉vT绳=m0g小车及车上粮食匀速上行时,设斜坡倾角为θT绳+F拉=(m1+m2)gsinθ+k(m1+m2)g卸粮后,小车匀速下行时T绳+km1g=m1gsinθ由以上各式得k=0.1,sinθ=0.5(2)关闭电动机后,小车与粮食向上减速运动,设加速度大小为a,由牛顿第二定律有(m1+m2)gsinθ+k(m1+m2)g-T=(m1+m2)a对配重受力分析,由牛顿第二定律有T-m0g=m0a由运动学公式有02-v2=-2aL由以上各式得L=67185mʈ0.36m答案(1)mv20sin2β2qL㊀(2)qBdm㊀(3)(d,d)㊀(4)2(2+1)πmqB解析(1)离子甲在电场中的运动可看成是类平抛运动的逆过程在z轴方向上:L=v0cosβ㊃t在y轴方向上:v0sinβ=at由牛顿第二定律有qE=ma02联立可得E=mv20sinβcosβqL=mv20sin2β2qL(2)当离子甲以最大速度vm进入磁场Ⅰ时,离子在yOz平面内做圆周运动,轨迹半径设为R1,由洛伦兹力提供向心力有Bqvm=mv2mR1离子运动半周后从y轴上y=2R1处沿z轴负方向进入磁场Ⅱ,在与磁场Ⅱ平面垂直的平面内做圆周运动,轨迹半径设为R2,则有22Bqvm=mv2mR2为使离子甲能始终在磁场中运动,对应于最大速度时粒子在磁场中运动的轨迹半径应满足R1ɤd㊁R2ɤ3d联立取二者中较小值可得vm=qBdm(3)根据洛伦兹力提供向心力,Bqv=mv2R,离子甲在磁场Ⅰ㊁Ⅱ中轨迹半径分别为RⅠ=mvqB=d2㊁RⅡ=22d离子在磁场Ⅰ中转动半周从y轴上第二次穿过xOy平面,在y轴上位置坐标y=2RⅠ=d由RⅡ=2RⅠ可知,离子在磁场Ⅱ中转动半周恰好从x轴上第三次穿过xOy平面回到磁场Ⅰ中,在x轴上位置坐标x=2RⅠ=d离子回到磁场Ⅰ中后在x=d的平面内做圆周运动,转动半周第四次穿过xOy平面,此时位置坐标为(2RⅠ,2RⅠ)即(d,d)(4)离子乙在两磁场区域中运动的轨迹半径分别为RⅠᶄ=4mvᶄqB㊁RⅡᶄ=2RⅠᶄ由于12mv2=12ˑ4mˑvᶄ2解得RⅠᶄ=d,RⅡᶄ=2d㊁vᶄ=qBd4m由于离子甲在两磁场区域内运动轨迹半径分别为RⅠ=d2㊁RⅡ=22d则在离子甲完成两次周期性运动处㊁离子乙完成一次周期性运动处轨迹产生第一个交点,则两离子运动到第一个交点处的时间差为Δt=π(RⅠᶄ+RⅡᶄ)vᶄ-2π(RⅠ+RⅡ)v=2(2+1)πmqB技巧点拨㊀带电粒子垂直进入匀强磁场中后做匀速圆周运动,轨迹平面垂直于磁场;粒子能不能从某磁场边界穿出磁场区域的临界状态是轨迹与该边界相切;界面两侧均存在磁场时可形成在边界两侧的周期性运动㊂答案见解析解析(1)A与B发生弹性碰撞,mA<mB,则A碰撞后反弹,以向右为正方向,满足mAv0=mA(-vA)+mBvB12mAv20=12mAv2A+12mBv2B解得vA=2m/s,vB=2m/s(2)与挡板碰前A向右匀速运动时,B静止不动,与挡板碰后,A先向左匀速运动,后向左做匀减速运动,A未减速时B的加速度大小满足μ2(mA+mB)g=mBaB解得aB=3m/s2A减速时加速度大小为aA=μ1mAgmA=4m/s2经过分析,A和B碰撞后运动的v-t图像如图所示,设碰后A匀速运动的时间为t2,减速运动的时间为t3,则有t3=vAaA=0.5s12A减速运动的位移大小x3=vA2t3=0.5m根据题意,x3为减速阶段的位移,即A开始减速时Oᶄ已向右移动了0.5m,则有vBt2-12aBt22=0.5m解得t2=13s(另一解舍去)故B光滑部分长度d=vAt2+x3=76m(3)A㊁B碰后经过时间t2后A和B之间有摩擦力,此时B的速度为vBᶄ=vB-aBt2=1m/sB的加速度满足μ1mAg+μ2(mA+mB)g=mBaBᶄ解得aBᶄ=133m/s2B在此后减速运动的位移xB满足2(-aBᶄ)xB=0-vBᶄ2解得xB=326mA对B的摩擦力所做的功为Wf=-μ1mAgxB=-365J(4)碰撞前对小球:MgL=12Mv2碰撞后对小球:MgL(1-cos5ʎ)=12Mvᶄ2若为弹性碰撞,则有vᶄ=M-mAM+mAv解得MmA=1+1-cos5ʎ1-1-cos5ʎ若为完全非弹性碰撞,则有Mv=(M+mA)vᶄ解得MmA=cos5ʎ1-cos5ʎ故1+1-cos5ʎ1-1-cos5ʎ<MmA<cos5ʎ1-cos5ʎ22。

AToday almost everyone knows computers and the Internet. If I ask you “What is the most important in your life?”, maybe you will say “Computers and the Internet. ”The first computer was made in 1946. It was very big but it worked slowly. Today computers are getting smaller and smaller. ?But they work faster and faster. What can computers do? A writer has said, “People can’t live without computers today. ”The Internet came a little later than computers. It is about twenty-five yearslater than computers. ?But now it can be found almost everywhere. We can use it to read books, write letters, do shopping, play games or make friends.Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making the “unreal friends”that they can’t put t heir hearts into study. Many of them can’t catch up with others on many subjects because of that.We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.26. The Internet can not be used for ____.A. studying?? ??????B. thinking??? ?????C.?shopping????D. playing27 .When the first computer was invented, it was ____.A. large and worked quickly????? ?????B. small and worked slowlyC. large but worked slowly??????? ???D. small but worked quickly28.

These “unreal friends”often meet each other.C. Students use the Internet to make “unreal friends”.D. Students know the friends on the Internet very well. ?30. What does the writer think of the Internet?A. It is helpful, but we can’t do everything on it.B. It can make students study harder.C. It is not good for students. ???D. It is wonderful. ?BHere’s an unusual story:a diamond ring was recently found in an egg. The magician,Liu Qian,discovered it, in front of an audience of millions at CCTV’s Spring Festival Gala. Liu’s magic tricks have made the centuries-old art of magic fashionable once again, and made him the hottest magician in China.As a seasoned young magician from Taiwan, Liu is popular worldwide for his magic shows. Countries he has performed in include the United States, Japan, South Korea and the UK.Witnessing something impossible happen right before your eyes is the root of people’s love for magic.Liu is known for his interaction (互动) with his audiences. He has a unique understanding of showmanship (演出技巧).It’s actually thinking rat her than one’s operation skills that is more important to achieving a successful magic show. We think carefully about how to design the shows creatively, to make them appear more interesti ng. ” Liu said.Liu Qian’s success dates back to his childhood. Born in 1976 in Taiwan, hefound himself attracted to a magic toy in a shop when he was seven years old. At the age of 12, he won Taiwan’s Youth Magic Contest, which was judged by the great American magician, David Copperfield.Yet, Liu never planned on becoming a professional magician. He studied Japanese literature at university and only hoped to be a magician in his spare time. However, his failure to find a proper job after graduation pushed him towards magic as a career. He has performed on streets, roads and fields, for passers-by, policemen and farmers.“Street shows are the biggest challenge for us magicians. We have to deal with unexpected situations and tough crowds,” Liu said.31. The story is about________.A. how Liu Qian became China’s hottest magicianB. why people love magicC. what magic tricks areD. how fashionable magic is32. The underlined word “Witnessing” means _____.A. LookingB. ProvingC. SeeingD.Signing33. People love to watch magic because________.A. they can’t figure out the secret of magicB. it arouses (激发) their curiosityC. they love watching magicians make the impossible happenD. it is a centuries-old art34. Which of the following is the key reason that Liu Qian decided to makemagic his career?A. He was interested in magic when he was littleB. He had won Taiwan’s Youth Magic Contest.C. He became an amateur magician in his spare time.D. He couldn’t find an acceptable job after graduation.35. From the story we learn that Liu Qian________.A. is at the age of 12B. is popular worldwide for his magic showsC. planned on becoming a magician from his childhoodD. does street show to make more moneyCOne of the most popular American singers of the 20th century was Elvis Presley. He made the Rock& Roll music popular all over the world. He sold millions of records and made many successful films, and he helped change the direction of popular music in the 1960s.Elvis Presley was born in 1935. His parents were simply country people who often took him to church,where he learned to sing, and he never forgot the kind of songs that he used to sing in church as a child.When he was young ,Elvis moved from Toledo to Memphis in Tennessee, where he attended high school. But he was not a very good student. His only real interest was singing. He began to sing in the style that is popular in the style that was called “country and western.”In 1955 he recorded some songs for his mother’s birthday. The peopleat the studio liked his singing and his music. It was country and western music, but it also sounded a little like the music which black people used to sing in the American south, It was called “blues”.Shortly after that, Elvis met Tom Parker, who became his manager and arranged concerts for him across the United States and new recordings as well. Soon Elvis became famous around the country. Later Elvis went to Hollywood and began to appear in films such as Love Me Tender and King Creole.But Elvis found it difficult to live with success. Like many other famous people, he began to take drugs and his health started to suffer. When he died at an early age of 42 in 1977, his many millions of fans were shocked.“The King is dead!”the newspaper said. But today his memory and his music live on and will always be remembered as the King of Rock& Roll.36. From the passage we can see ____.A. the church songs didn’t help Elvis develop his own styleB. Elvis sang songs in the style that was called “blues”C. Elvis didn’t get any help from his parentsD. the church songs helped Elvis’ development in his singing37. Who was Tom Parker?A.

For example, you may be a shy person and you don’t like it; you wish you are an outgoing person. You might then think that you are not smart enough. All these give reasons to you not to like yourself. Fortunately, there are always things you can do to make you like yourself. Here are some tips:1. Write your success storiesOne reason we may not like ourselves is that we are too focused on whatwe don’t have that we forget about what we(already) have. So make a list of your achievements; write your success stories. They do not have to be big things; there are a lot of small but important achievements in our life.2. Accept things you can’t changeThere are some things you cannot change,such as your background and your past. So learn to accept them. You will feel much relieved if you treat things you can’t change the way they deserve:just accept them,smile,and move on.3. Focus on your strengthsInstead of focusing on your weaknesses,focus on your strengths. You always have some strengths which give you a unique person. Recognize your strengths and build your life around them.4. Stop comparing yourself with othersYou are unique. You can never be like ___________,and neither can other people be like you. The way you measure your success is not determined by other people. Instead,it is determined by your own life purpose. You have everything you need to achieve your life purpose,so it’s useless to compare yourself with others.41.
