红鲤鱼与绿鲤鱼绕口令

已知水箱体积,排水管管径,假设300秒排完,求流速水箱长宽高：2380mm*1080mm*1120mm,管内径：d=78mm,长度不计,时间t=300s,求流速 流体力学:从圆孔出流时,流出10L水需时间T,水箱作用压头恒定,试确定圆孔截面收缩.流速.流量.局部损失系数用试验方法测得从直径d=10mm的圆孔出流时,流出10L的水需要时间T=32.8s,水箱作用压头 七、按课文内容填空 齿轮的齿数都是双数的么? The plants are under the desk.变成一般疑问句前面是用do,还是用does 将It's under the boy's desk改为一般疑问句快 契税 土地增值税 房产税,城镇土地使用税如题,它们的异同点 契税 土地增值税 城镇土地使用税 房产税有什么区别与联系啊 ______many flowers there are on the teacher’s desk A,What B,How C,How too D,What so 为什么? ——many flowers there are onthe teacher's desk!A what B how C how too D what so -- many flowers there are on the teacher's desk!A.What B.How C.How too D.What so这道题该选哪一个啊本题的答案是D，请问是为什么？ The person I like初中生水平,1分钟以内,要用过去式!真的很谢谢,不要太难的. 设0 被减数比差多10,比减数多30,则减数是被减数的【 】% 英译中：In what way dose echo-location in bats play an untilitarian role?echo-location in bats 是什么结构?In what way 不好意思是utilitarian 被减数增加30减数减少10得到的差会是几 The location is beside twin towe.Is this correctWhich is correct.1)The location is beside Twin Tower.2)The building is located beside twin tower. where this location is?有无语法错误?原句是“HI,could you do me a favor and tell me where this location is?"貌似应该是“where is this location?难道是在并列句中会有语序改变? 17-7=10里什么是被减数,什么是减数,什么是差? 设0 WQ GIP 网友的话 gip j shn tfkf yry wq shn wq q imc e cyna wq Q SHNY KKD I J LD O WQ WU ,Q KKD B BN I J LD O WQ WU ,Q FTJB I TDK J Q D P FP R DY VB GIP J大概是五笔 谁能猜出这些字母的含义"q ny pw rrrr .cf wq rw yneg .q i j q .wq gip j wq " 定积分求曲线长度问题 第二十五题 对积分区间有点疑问 为什么是从0到二分之pi x从0到a定积分求曲线长度问题第二十五题 对积分区间有点疑问 为什么是从0到二分之pi x从0到a 应该是从二分 定积分方面的问题： 曲线X^（2/3）+y^（2/3）=a^（2/3）的（a>0）的长度为? 怎么算啊?谢谢各位大虾! 客人的一句话,求翻译：so she does not know who the person is that is not following up on this Why is there so much insecurity in love?Is it because people don't know the meaning of true love?Some people stay together forever,but and more often we see people break up.. What makes us insecure?Ego? give up.I love you,but you can't have you,there are too many obstacles between,I don't like the cowardly man,goodbye.
