四川省棠湖中学2019届高三上学期开学考试理综物理试题1.自然界中很多元素具有放射性,对放射性元素原子核衰变的特点,以下说法正确的是A. 衰变现象表明原子具有核式结构B. 根据玻尔的原子理论,氢原子的核外电子由高能级跃迁到低能级时,氢原子核发生衰变C. 放射性元素的半衰期不会因环境变化而变化D. 衰变过程中的质量是守恒的【答案】C【解析】【详解】A项:衰变现象表明原子具有复杂结构,故A错误;B项:根据玻尔的原子理论,氢原子的核外电子由高能级跃迁到低能级时,要释放一定频率的光子,故B错误;C项:半衰期是由原子核内部结构决定的,与原子所处的化学状态和外部条件无关,故C正确;D项:衰变过程中的质量数是守恒的,但质量不守恒,故D错误。

2.从同一地点先后开出n辆汽车组成车队在平直的公路上行驶,各车均由静止出发先做加速度为a的匀加速直线运动,达到同一速度v后改做匀速直线运动,欲使n辆车都匀速行驶时彼此距离均为s,则各辆车依次启动的时间间隔为(忽略汽车的大小)()A. 2v/aB. v/2aC. s/2vD. s/v【答案】D【解析】设某辆车从静止开始做匀加速直线运动经过时间t速度恰好达到v,其前面一辆车运动时间为t+△t,则,,联立上述方程得各辆车依次启动的时间间隔.故选D。

【点睛】设某辆车从静止开始做匀加速直线运动经过时间t速度恰好达到v,其前面一辆车运动时间为t+△t,根据两车的位移差为s即可求解.3.2016年8月16日凌晨,被命名为“墨子号”的中国首颗量子科学实验卫星开启星际之旅,这是我国在世界上首次实现卫星和地面之间的量子通信,构建天地一体化的量子保密通信与科学实验体系。

如图所示,“墨子号”卫星的工作高度约为500km,在轨道上绕地球做匀速圆周运动,经过时间t(t小于其运动周期),运动的弧长为s,与地球中心连线扫过的角度为β(弧度),引力常量为G。

则下列关于“墨子号”的说法正确的是()A. 线速度大于第一宇宙速度B. 环绕周期为C. 质量为D. 向心加速度小于地球同步卫星的向心加速度【答案】B【解析】试题分析:第一宇宙速度为最大环绕速度,即为轨道半径等于地球半径轨道上卫星的环绕速度;根据角速度的定义以及求解周期;根据比较向心加速度的大小.第一宇宙速度为近地卫星环绕速度,也为卫星最大环绕地球运动的速度,故由于“墨子号”轨道半径大于地球半径,所以其环绕速度小于第一宇宙速度,A错误;“墨子号”经过时间t (t小于太空电站运行的周期),它运动的弧长为s,它与地球中心连线扫过的角度为β(弧度),则太空站运行的线速度为,角速度为,环绕周期为,B正确;绕地球做匀速圆周运动,万有引力提供向心力,即,计算过程中卫星的质量相互抵消,不能计算卫星的质量,C错误;根据公式可得,所以半径越大,向心加速度越小,因为墨子号的运动半径小于同步卫星的运动半径,故“墨子号”向心加速度大于地球同步卫星的向心加速度,D错误.4.有一种电荷控制式喷墨打印机,它的打印头的结构简图如图所示。

A museum guide. Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake. This robot looking like a helicopter (直升机), is called the detector-bot . It's about 4 meters long, and it took about 4 years to develop the model. Its main functions (作用)are to collect information from the air, and send goods of up to 30kilos, to people stuck in an earthquake. This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, "Unlike other automatic machines, the most important feature of this robot is that it doesn't need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour. " This robot has a different function --- it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go. As well as a detector (探测器)that finds victims (遇难者)and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark. Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids. Experts have said that the robots will enter production, and serve as part of the national earth- quake rescue team as soon as next year. 4.Which of the following statements about the robot is true according to the passage?. A . It hasn't been put into production so far. B . It is a machine with a length of 10 meters. C . It is a machine carried by a helicopter. D . It weighs about 30 kilos. 5.Dr. Qi Juntong thinks this robot is different from the others mainly because _____. A . it has more functions B . it has a more advanced camera此卷只装订不密封 班级姓名准考证号考场号座位号C.it can change as the environment changesD.it can work by himself once given the information6.The underlined word "which" in paragraph 6 refers to_____.A.a camera B.a detectorC.a rescuer D.a doctor7.What is the passage mainly about?A.The appearance of the robot. B.An introduction to the robot.C.The reason for making the robot. D.Some information about earthquakes.Having friends may well keep you healthier and help you deal with stress better. Some studies show that people with close friends have a greater ability to fight disease than people who are alone.Place friendship in the first place. Find the time to be with friends even if it means letting the lawn(草坪) go unmowed(未割的) or the dishes unwashed for a while. When you can’t get together, use the phone to keep in touch.Open up to close friends. Keeping a deep friendship requires a level of “heartfelt” intimacy (亲密).Don’t be afraid to express your inner fears and disappointments. Listen to your friends when they have problems,but offer advice only when it’s wanted. Help raise friends’ self-esteem(自尊) when they are sad about a job loss, or other such events.Have different friends for different activities, such as going to the movies,singing in a choir,and joining in a bowling league.Don’t wait for a friend to ask for helps.

四川省棠湖中学2019届高三物理上学期第三次月考试题(含解析)

四川省棠湖中学届高三上学期第三次月考理综物理试题年是居里夫妇发现了放射性元素钋()周年。

若元素钋发生某种衰变,其半衰期是天,衰变方程为。

下列说法不正确的是. 该元素发生的是β衰变 . 原子核含有个核子. γ射线是衰变形成的铅核释放的 . 的经天,已发生衰变的质量为【答案】【解析】根据衰变方程为,可知,是,属于衰变,而射线是伴随着衰变产生的,错误;根据电荷数守恒和质量数守恒得,的电荷数为,质量数为,则核子数为,正确;射线是衰变形成的铅核释放的,正确;根据知,的经天,还剩余,故已衰变的质量为,正确..物体做匀加速直线运动通过的位移,已知它通过前所用的时间为,通过后所用的时间为,则物体的加速度的大小为. . . .【答案】【解析】【分析】根据匀变速直线运动中间时刻的瞬时速度等于这段位移的平均速度,可以求得两部分位移的中间时刻的瞬时速度,再由加速度的公式可以求得加速度的大小。

【详解】物体作匀加速直线运动在前一段所用的时间为,平均速度为:,即为时刻的瞬时速度;物体在后一段所用的时间为,平均速度为:,即为末速度所以加速度为:故应选:。

【点睛】利用匀变速直线运动中间时刻的瞬时速度等于这段位移的平均速度这个结论,可以很容易的做出这道题,本题就是考查学生对匀变速直线运动规律的理解。

.在空中同一位置水平抛出初速度不同的两个小球(忽略空气的影响),则在从抛出开始. 下降相同高度时初速度较大的球的速度与水平方向的夹角大. 下降相同高度时初速度较小的球在竖直方向上的速度较小. 通过同一水平距离时速度较大的球在竖直方向上的速度较大. 通过同一水平距离时速度较大的球在竖直方向上的速度较小【答案】【解析】【详解】、项:设球的速度与水平方向的夹角为,则,由可知,下降相同高度时,相同,初速度越大所以球的速度与水平方向的夹角越小,故、错误;、项:由水平方向的匀速直线运动可知,,初速度大的所用时间少,由可知,初速度较大的,竖直方向上的速度较小,故错误,正确。

1.2018年3月14日,英国剑桥大学著名物理学家斯蒂芬·威廉·霍金逝世,享年76岁,引发全球各界悼念。

在物理学发展的历程中,许多物理学家的科学研究推动了人类文明的进程,为物理学的建立,做出了巨大的贡献。

在对以下几位物理学家所做的科学贡献的叙述中,正确的是A. 卡文迪许将行星与太阳、地球与月球、地球与地面物体之间的引力规律推广到宇宙中的一切物体,得出万有引力定律,并测出了引力常量G的数值。

B. 根据玻尔理论,原子从激发态向基态跃迁时将释放出核能C. 布拉凯特利用云室照片发现,粒子击中氮原子形成复核,复核不稳定,会放出一个质子。

D. 爱因斯坦的光子说认为,只要增加光照时间,使电子多吸收几个光子,所有电子最终都能跃出金属表面成为光电子。

【答案】C【解析】【详解】牛顿将行星与太阳、地球与月球、地球与地面物体之间的引力规律推广到宇宙中的一切物体,得出万有引力定律,并测出了引力常量G的数值,选项A错误。

根据玻尔理论,原子从激发态向基态跃迁时将释放出光能,不是核能,选项B错误;布拉凯特利用云室照片发现,粒子击中氮原子形成复核,复核不稳定,会放出一个质子,选项C正确;根据爱因斯坦的光子说认为,只要入射光的频率小于截止频率,即使增加光照时间,也不可能发生光电效应,故D错误;故选C.2.气象研究小组用图示简易装置测定水平风速。

【答案】(1)如图所示:
(2)AC
【解析】 试题分析:(1)如图所示,注意滑动变阻器的接法是限流接法。
(2)根据公式
滑块的加速度
;木板的加速度
,滑块与平板车静止前取得相
同 的 速 度 时 : v0-a1t=a2t , 解 得 t=1s , v=1m/s, 选 项 A 正 确 ; 当 两 者 达 到 共 速 时 , 此 时 木 板 的 位 移
;滑块的位移
;此时滑块相对木板滑行的距离为
∆x=x1-x2=2.25m,达到共速后,因木板的加速度大于滑块的加速度,则滑块继续减速运动,直到停止在木 板上,但相对木板向前滑动,选项 B 错误;滑块相对木板向前滑动时木板的加速度
A. 线圈转速为 100π rad/s B. 0.01s 末穿过线圈的磁通量最大
C. 通过线圈的最大电流为 10A D. 伏特表的示数为 90V 【答案】C 【解析】 试题分析:线圈在中性面时磁通量最大,电动势最小,与中性面垂直时,通过的磁通量最小,变化率最大, 电动势为最大,电压表测量的为有效值
A. 电子一定从 A 向 B 运动 B. 若 > ,则 Q 靠近 M 端且为正电荷 C. 无论 Q 为正电荷还是负电荷一定有 < D. B 点电势可能高于 A 点电势 【答案】BC 【解析】 由于不知道电子速度变化,由运动轨迹图不能判断电子向那个方向运动,故 A 错误;若 aA>aB,则 A 点离 点电荷 Q 更近即 Q 靠近 M 端;又由运动轨迹可知,电场力方向指向凹的一侧即左侧,所以,在 MN 上电场方
