找有关平抛加速度的公式及实际上路程公式

上半部分:
When standing in front of the podium, most people will feel a little nervous. However, I am the minority. I am very nervous.
Well. Today, I want to talk about protecting spiders. First, I want to ask you all a question.
When you see a spider web. Will you try all kinds of means to destroy it?
If there is a spider on the web, will you try to kill it?
For a lot of people, in their subconscious, they consdier spiders as their enemies. But in fact, spiders are human's friends.
下半部分:
As we can see, spiders don't hurt us. On the contrary, they help us. Although spiders may look scary, that is just appearance. Spiders are arthropoda. It is different than those insects that are harmful to human beings. Similarly, if spiders show up in your house and you find a spider web, that means the spider is reminding you that your room needs to be cleaned.
I wish everyone can love all kinds of animals in this world, including spiders. (你想说的是包括蜘蛛吧?) Many creatures have became the victims during the process of human's civilization. For us, for our world, from now on, let's learn how to make peace with animals.
Thank you all for listening. Thanks.
最后帮你省略了一下演讲到此结束.因为我写了“谢谢你们的聆听”这一般就是意味着结束了.如果你想要写“演讲到此结束.”你可以说"This is the end of my speech."
你先看下··有问题请追问

不是

1、关羽有睿智、深藏不露并且心机很深的性格特点,也体现了他对事物的不同认识与深刻看法.
2、这是三国演义第66回关云长单刀赴会的场景,在刘备既得益州后孙权向他讨要荆州,并邀请关羽去参加谈判,大多数人不赞成,而关羽以勇气单刀赴会,并慷慨陈词,维护蜀国利益的局面.
3、千里走单骑、水淹七军、走麦城等

使用了【拟人的修辞手法】
【分析】：把无名指和食指比喻成关平和周仓两个人,把某样东西带上了人的特点,因此毫无疑问是【拟人手法】

养尊处优:【解 释】 养:生活;尊:尊贵;处:居于;优:优裕.指处于尊贵地位,过优裕生活.【出 处】 宋·苏洵《上韩枢密书》:“天子者,养尊而处优,树恩而收名,与天下为喜乐者也.”
关公 关平 周仓 三国演义,关平是关羽的义子,周仓替关羽拿刀.

这个好上手.
利用斜坡的目的是计算该星球的表面的重力加速度,设为g星.
在斜面上方运动了时间t,下落高度h=1/2g星t²
水平方向距离x=vt
在斜面上,tan@ = h/x =(g星t)/(2V) → g星=(2Vtan@) /t
在该星球近地面做匀速圆周运动的航天飞机速度最大,设为Vm
由万有引力可得：(GMm)/R²=mV²/R 结合黄金代换式GM=gR².得到
V²=√（GMg星）=√（2GMVtan@/t）所以V=√（√（2GMVtan@/t））不太好表示,但愿你看得懂.斜面上平抛神马的解题方法的话,最好自己去总结领悟,不过记住将运动分解成水平与竖直,利用好斜面倾角,有这两点的话,解题应该没问题.
