九师联盟高三九月质量检测巩固卷
九师联盟高三九月质量检测巩固卷哎,九月到了,时间真是飞得像脱缰的野马,转眼间又是一年高三,大家都在忙着准备这次的质量检测。
说实话,心里那叫一个五味杂陈,紧张、期待、还有点小兴奋,简直像是在过山车上,刺激得很。
每天早上起床,看着镜子里那张愁眉苦脸的脸,心里默念:“加油啊!要是能把这些知识都牢牢抓住就好了。
”可现实嘛,书本一打开,满眼的公式、定理,头都大了。
真是应了那句老话,“不怕困难,就怕心烦”。
大家一块儿复习的时候,总是免不了要互相调侃。
有的同学看了几道题,脸上的表情就像是吃了柠檬似的,苦得厉害。
别提有多搞笑了,旁边的朋友立马就来一句:“别紧张,题不会吃人!”结果大家笑得前仰后合。
说到底,这种轻松的氛围真的是对抗压力的良药。
学习嘛,不就是个坚持的过程吗?每天早上起来对着书本,感觉像是在和知识摔跤,有时候摔了个四脚朝天,有时候却又能翻个身,找到一点点小窍门。
我们班的李老师也总是笑着说:“同学们,知识就像一块饼,大家分着吃,谁也别争。
”听得大家都乐了。
可谁知道,真正复习起来,拼的是谁的战斗力啊。
尤其到了临考前那几天,简直就是“飞蛾扑火”,拼命想把脑袋里的知识塞满。
大家互相加油,形成了一种不言而喻的默契。
每当看到谁在努力,就想为他打call,“兄弟,加油!你是最棒的!”在这个过程中,还是要感谢那些陪着我们一起熬夜的小伙伴。
每当深夜,那灯光透过窗帘,映出一张张专注的脸,仿佛是为了追逐梦想在奋斗的勇士。
回想起以前,谁不想躺在床上多睡一会儿呢?可是,想着未来的路,就像是给自己打了鸡血,心里顿时又充满了干劲。
我们常常会说:“再苦再累,咬牙坚持,总会见到曙光。
”这句话成了我们的座右铭,反复默念,给彼此打气。
这个过程也不是一帆风顺的。
有时候复习得特别累,心情就像是被压在了沙子底下,透不过气来。
这个时候,大家就会聚在一起,聊聊那些轻松的话题,打打游戏,释放一下压力。
生活总是要有些乐趣,不然怎么撑得过去?于是,我们就像打仗一样,时而认真复习,时而开怀大笑,保持一种平衡,才能走得更远。

使钩码的质量远小于小车的质量解析:(1)实验必须平衡摩擦力、必须调节定滑轮高度,使牵引小车的细线与长木板平行,目的使小车受到的合外力等于细线的拉力,必须先接通电源,后释放小车;由于是探究加速度与合外力关系,因此要保证小车的质量不变,改变钩码质量来改变合外力,选项A 、B 、D 正确,C 错误.(2)根据逐差法可得小车的加速度大小.(3)若不断增加小桶中砂的质量,图像中各点连成的曲线将不断延伸,当重物质量无限大时,重物将近似自由落体运动,所以加速度a 的趋向值为g ;为避免图线出现弯曲,可采取的措施是:使钩码的质量远小于小车的质量.13.解:(1)甲车启动后,速度达到20m/s 所用的时间乙车启动后在末的速度因此当乙车速度达到20m/s
