很傻的物理题.重20N的物体在斜面上匀加速下滑,斜面倾角为37度,若斜面光滑,求加速度大小

1、你把天线往下拉,稍微弯一点没关系,下面还有空缺,小心折过来
2、你看一下,车底和遥控器上有评率,在一张贴纸上,如果不同就能比赛,相同的话别比了,会撞的.
3、你可以买牙箱和锂电池加速.别的我不会,叫你两招
闪电漂移.
先加速,到弯道减速,然后转向,并且迅速刹车,大概刹半秒立马加速,不要一下到三档,慢慢推上去,就能漂移.如果出问题了,松油门,加转向就能刹车.
旋风乱舞.
加速,转弯,一直转,就可以自转了.小心控制,控制不好就松油门,朝另一个方向转,就能刹车.

唾手可得
信手拈来
易如反掌
手到擒来
小菜一碟
家常便饭
不费吹灰之力

四六不懂
老糊涂
一脑子浆糊

1.形容人傻,傻得连小孩子都知道的常识也没有
俗语/习惯说法:"连三岁小孩儿都不如!"
2.形容事情简单,连小孩子都会.
暂时没想出来...
也可以说,"连三岁小孩儿都会"吧...
成语:妇孺皆知,(fù rú jiē zhī)
孺：小孩.指妇女、小孩全都知道.形容众所周知.
这个成语更多的是讲一件事情,大家都知道而不一定是说事情简单,连小孩子都会.

作文向日葵其实很傻 【答案】:秋天，走进校园，一缕清香扑鼻而来，那一定是桂花。情人节时，女孩子们受伤拿的那些花，白的、红的、黑的，哦！那是玫瑰花。母亲节时，妈妈们含着炽热的泪水，深情地接过孩子送去的花，哦！那是康乃馨。面对人们对她们深厚的感情，向日葵伤心极了。 这天，向日葵伤心地对太阳公公说：“太阳公公，为什么我长得这么高大，在花中鹤立鸡群。但人们却还总是把玫瑰花、月季花、康乃馨之类的一些花说的那么美呢？我也是花啊！人和人是平等的。为什么花和花却不能平等呢？这不公平！” 太阳公公拧拧我的鼻子，亲切地说：“孩子，她们是比你漂亮，但是......” “哼！连你也来挖苦我！呜呜~~我真的那么不如她们吗！”向日葵打断太阳公公的话，自卑地说。 太阳公公马上说：“不是的啊，人们常说‘人不可相貌’，其实花也是不可相貌的啊！玫瑰花她们并不是比你好。因为你能结出丰厚、好吃的果实，而她们不能。她们能开出妖艳、美丽的花朵，而你不能。其实，你们是平等的。” 向日葵听了以后深受启发。原来每个人都有自己的用处，我就是所谓的“幕后英雄”。

对的.
齐次线性方程组的基础解系不是唯一的 !
如果需要正交化的话, 得出 (-1,0,1)后, 可这样计算另一个解向量:
令 x1=x3=1, 代入x1+x2+x3=0 得 x2=-2
即得正交的基础解系 (-1,0,1), (1,-2,1)

从语法上讲are you finished 和 have you finished都是对的,have you finished比较强调动作上的结束,比较接近“你终止了吗?你做完了吗?”.are you finished 比较强调感觉上的结束,“你够了吗?你有完没完?”.但是是 finished ,不是finish.

愚公为的是自己的子子孙孙和太平村,愚公想要子子孙孙的太平村的所有村民走向富裕的道路.之所以才去挖山叫子子孙孙去吃这苦头.

Μπορείτε πραγματικά ανόητο

全部吗?
I thought that I will not have the idol, because the present makes a debut newly a singer song has not been able to let me shock, I will not be that kind of me to think the very silly matter--Pursues the star. I once looked down upon the human who pursues the star, I thought that is very silly, because you, even if does again for him many, he will not give you anything. But, when I after hearing opera2 which Wang Lixin sings, I liked him, might say, I was because of he advantageous sound, that could not be broken through porpoise sound. From infancy to maturity, I admire the human who will sing, will specially sing the treble, today I met. He is Hunan Changde person, only then 18 years old, this year only then just rose high three. “18 years old, such performance is very really loathful, because you sing the skill exceeds many 28 year-old” these words, is the appraisal committee identically to his appraisal, is also because of his unique treble, made him to crash in national 13, it is a pity, it, in 7 entered in 6 competitions, because of the number of votes reason, left the joyful male voice stage. But, we will never forget that this 18 year-old big boys, he have given us too many joys; He has given us too many courages; He has given us too many moves; He has given us in this ordinary summer the extraordinary singing sound .So long as has him, we will not feel sad, he will be that kind frank and the sincere person.
2）Regards a singer, can use the appearance really to weigh? Wang Lixin is not commander-in-chief in the numerous contestants, can only say is lovable, his eye is very limpid, is very pure. Even if the appearance prominent is also what kind, regards a singer, must think whether his singing sound does move us, must think his moral character quality .I from do not have like a person blindly, has not met the singing sound in the past's 12 years to be able to move my heart's person, but, notes Wang Lixin in me, I recognized, he is in my heart's god. I believed that likes Wang Lixin the oak tree confusing, has the similar disposition and the ideal person with Wang Lixin, we are deeply loving music at least, understands the appreciation true music.
3）Under his stage's lovable, was a stage cannot unfold by far, now many people pursue the star are only the only semblances. Actually, I thought that what any entertainers are the hope are been affirmative is the strength, but is not other, neglected the strength to pursue the star is blind. I no longer thought that pursued the star is the very silly behavior, depth in which, could understand, this was the matter which remembered with eternal gratitude.
4）You have the sound which the heaven grants,
you have a unique self-confidence,
the charm which you on the body send out,
you are most special only.
5）I like the expression which you smile,
I, so long as you live the happiness,
I can listen to you to sing am a kind of good fortune,
I will protect forever you.
6）Wang Lixin the good sound only wants to sing to you listens,
I am willing in here,
to accompany you to love your one century,
Wang Lixin the good sound only want to sing to you listen,
the wind or rain Jing Huoji,
I will give you the infinite courage.
7)How in the future could pass,
regardless of how also did have me,
your smiling face warm oak tree confused the pit of the stomach,
Wang Lixin the good sound only wanted to sing to you listens,
I was willing in here,
to accompany you to love your one century, Wang Lixin the good sound only want to sing to you listen,
the wind or rain Jing Huoji,
I will give you the infinite courage.

首先N=1时,6能被6整除
设当N=K时,K^3+5K能被6整除
当N=K+1时,
n^3+5n=K^3+5K+3K(K+1)+6
因为
K^3+5K能被6整除
K和(K+1)中肯定有一个是偶数
所以
3K(K+1)+6能被6整除
所以
如果当N=K时,n^3+5n能被6整除
当N=K+1时,n^3+5n也能被6整除

写出你小时候为什么傻也可以.
直接写开头“小时候,我很傻,想起来自己也不由自主的笑起来...”等等.
写小时候你干什么而“傻”.
如果可以就在加一段.
结尾可以首尾呼应.
其实我觉得这个题目不好写...

向日葵对太阳说：“谢谢你，你给了我阳光与温暖，让我开花、结果……”
太阳答道：“不用谢，让地球上的万物茁壮成长是我的义务！”

方法不对,事倍功半.方法正确,事半功倍.

社会本就是黑暗的,对别人好不一定就能得到好处.要知道,13岁的你慢慢开始融入社会,不能只是当别人的奴隶了,要做自己的主人,在社会上要敢于竞争.当然不是说去对别人拳打脚踢的.对于不还你钱的同学,你再也不要借钱了.你需要的是宽容对待,许多问题都是由宽容化解的.有的同学吃不惯这一套,你自然不能忍受,人的忍受是有限度的,每个人都是平等的,你有什么地方值得别人这样对待你.现在的你就是要懂得知道社会,去适当地反抗.强大需要靠自己,你有好的功夫,为什么要受欺负?而你一再退避下去只会招来他们的更加嚣张.

The classroom is cleaned by the students.
翻译：教室被同学们打扫.
教室The classroom
被打扫is cleaned （be动词+过去分词 表被动）
由同学们by the students（by+某人）
The classroom was cleaned by the students.
翻译：教室被同学们打扫了.
教室The classroom
被打扫了was cleaned （be动词+过去分词 表被动）
由同学们by the students（by+某人）
is 表一般现在时,was 表一般过去时,要看你所表达的意思.如果说教室常被学生打扫,教室是学生打扫的,表示经常发生的动作或存在的状态,那就是选第一种.如果说教室被学生们打扫了,打扫过了,那就选第二种,表示过去发生的动作.选什么都是对的=v=

I'm an easy-minded person who is stupid and fool,I can just use the most simple words to express myself.

I am silly,aren't I Hmm...Yeah,I admit that.
I know that you don't like me.
I will vanish,vanish from your sight line,forever after I spend all my money in my 152 telephone card.
You wouldn't get any message and news from me anymore.
Perhaps you'll miss me a litte,and so I do.
This is the only way to make you miss me.
Because I want you to know that I love you.

按LZ的意思,这里增大SO3的浓度是由于加入SO3引起的,而不是强制容器体积变化导致.且LZ说压强增加,那么考虑的是恒容条件下的平衡移动,即总体积不变,也就是说加入SO3不直接引起SO2、O2的浓度改变.
这个反应增加SO3的浓度是主动因素.因此直接用定义——反应速率来考虑即可.反应物浓度越大,反应速率越大.因为原来达到平衡,所以加入SO3后SO3分解的正反应速率大于逆反应速率,平衡向SO3分解的方向移动.
对于平衡问题,不要全用勒夏特列原理考虑,特别是这种模棱两可的可能会有多个条件的情况下,会使问题复杂化.

病菌一般是由有机物和无机盐水等成分构成,也就是说是一堆分子的集合,故而它比原子要大,也比一般的分子要大.
分子由原子构成,分子要比原子大.
但是近年来科学发展,发现有机大分子和生物大分子,还有聚合物分子,巨型分子（晶体）等等都很大,有时甚至超过病菌的大小.
还要阐述一下,病菌不是病毒,病菌是致病细菌,也就是细胞生物了.
病毒不具有完整的细胞结构,一般会更小.

原长=6÷（1-3/4）=24米
一根电线用去它的四分之三,就是还剩四分之一,四分之一是6米,所以原长是24米.

Xue,I am silly
I am loving you and waiting for you stupidly.
I wanna have your words,
Telling me that you love me
Telling me that you will never leave me alone
I will go forever together with you.
Thinkless and do nothing
Almost made myself mad due to be appealed by you
Xue I never stop loving you.
Until the date I will be dead.

How silly I am!

学汉语的时候先学的拼音,再学的笔画,再一个一个的字,最后句子文章,一步一步来的.后面慢慢的就开始学深奥的语法了.

大概是：
人要有希望,有目标,否则人就迷失了（迷茫了）,迷失的人是很不明智的,是傻的.

I used to be silly.

中英文不能一一对应.“要”这个字其实包含了几个不同的意思,“想要”、“将要”、“必要”、或“需要”,所以在翻译时要根据不同语境翻译成不同的英文,不能硬性地翻译成一个英文单词.比如：
1、我要那个玩具.
I want that toy.
2、我要离开了.
I am leaving.
3、架子要倒了.
The shelf is going to fall.
4、你要遵守法律.
You should obey the law.
5、吃饭前要洗手.
Wash your hands before eating.
（这句直接用祈使句,“要”字根本不需要翻译）
所以,“要”在很多情况下,可以翻译成want,但是在很多其它情况下,必须根据具体语境具体分析,不能一概而论.

don't be so nice to me.i am not clever that i will take it for true.

（头脑糊涂, 不明事理） stupid; muddleheaded; silly:

名词单数基本上不能够作为句子成分单独使用,要使成分完整,必须要和冠词一起使用,或者使用复数形式,under a table on a chair 语法上也是成立的,但是桌子椅子成千上万,不知道哪一个,所以用the,表示特定的那个

外星人是有的.根据目前所知,外星生物都来自很深远的宇宙,而我们人类连太阳系的航行都只处于起步阶段.所以能够判断到达地球的外星人的智慧一定比人类高出许多.为什么外星人一直没有和人类联系呢?原因就出在智慧等级的差距上,两种智慧等级有巨大差别的生命怎么沟通?现代人与非洲原始部落的人类之间信息都不能正常交换,更何况我们与外星人的智慧差距大到甚好超过人和猩猩.人能和猩猩世界联系沟通吗?

两层意思,第一个就是她喜欢你,第二个就是让你表个态,到底喜不喜欢她,就这样……

当秋风吹落了树叶上的枯叶,冬天的序幕便打开了.这时的太阳光变得懒洋洋的,似乎有些筋疲力尽了.姑娘和小伙子们一向是季节的风标,在人们还未留意时,新潮猎装和大衣便套在美丽的羊毛衫外.给冬天贴上了标志.
迈进校园,校门口的小榕树已经凋谢了,只有那些壮大一点的树还绿着,花坛上的花儿也渐渐羞涩着正休息着,只有叶子上还有亮晶晶的露珠.
场地上,三四个同学正在做值日,看着他们认真劲儿,好像不怕东风的呼啸.沙地上,有几个同学正玩着单杠;跑到上,有一些健身的同学正跑着……其他同学呢?哦,他们有的正急匆匆地往各自教室跑去,走去;有的坐在教室里读着书;还有的站在走廊上聊着天……
“零零零.”早读的铃声响了,顿时,校园突然寂静下来,没有刚才的喧闹了,只有那朗朗的读书声,此时,紧张的学习生活又开始了……
渐渐的,太阳忍不住露了出地平线了,一缕柔和的阳光照在校园中,仿佛校园穿上了金衣,照在同学的身上,让人感觉到一丝温暖,没有早晨的寒冷,觉得此刻的冬天就好比春天一样,那样温暖,那样舒服.
校园冬天很平凡,很普通.但它却又很美丽,虽然看不到那美丽的雪,但我去看到它那早晨的美,它是多么有趣啊,有谁会不喜欢这样的校园呢?
校园的冬天,我喜欢!

这两件事情没有很大关系吧!既然是送那就无所谓傻与聪明之分,只有愿意与否.要是真心的想和别人交朋友,而对方也是一个值得信赖的人的话,送个东西没什么吧,至少你是愿意的.不要后悔哪些无法挽回的事情,既然做了,那只能表明你送东西那时候的决定是正确的,至于你现在后悔,可能有其他原因吧.好好哟!

“Many boys dream of……”对
dream of 渴望着,梦想着
dream通常作动词
dream作为形容词只有“理想的”意思

的确,是个决定.
