|采纳率87.5%解题思路:第一宇宙速度7.9 km/s是指卫星绕地球表面在地球引力的作用下绕地球做圆周运动,了解同步卫星的含义,同步卫星在地球上空固定的高度上,其周期与地球自转周期相同,相对地面静止.A、第一宇宙速度是近地卫星的环绕速度,也是最大的圆周运动的环绕速度.而同步卫星的轨道半径要大于近地卫星的轨道半径,根据v=
GM
r,可以发现,同步卫星运行的线速度一定小于第一宇宙速度.故A错误;
B、因为同步卫星要和地球自转同步,即ω相同,根据F=
GMm
r2=mω2r,因为ω一定,所以 r 必须固定,故B正确;
C、根据万有引力提供向心力,F=
GMm
r2=mω2r,得:ω=
GM
r3,同步卫星的轨道半径要小于月球的轨道半径,所以同步卫星绕地球运行的角速度比月球绕地球运行的角速度大,故C错误;
D、同步卫星与赤道上的物体具有相同的周期,根据向心加速度的公式:a=
4π2
T2r,同步卫星的轨道半径要大于静止在赤道上的物体的轨道半径,所以同步卫星向心加速度比静止在赤道上的物体的向心加速度大,故D错误.
故选:B.点评:
本题考点: 人造卫星的加速度、周期和轨道的关系;万有引力定律及其应用.
考点点评: 本题考查了万有引力提供向心力,第一宇宙速度,线速度、角速度与轨道半径的关系,同步卫星的特点.比较两物体的线速度,角速度、周期与半径的关系只要找准相同的物理量就能顺利解决此类题目.1年前查看全部

- If we say the four great inventions (Gunpowder,Compass,Paper
If we say the four great inventions (Gunpowder,Compass,Paper and Art of Printing) reflected ancient China’s scientific achievements,then Zhaozhou Stone Bridge perfectly represented one of the greatest contributions to ancient China’s bridge building.Nobody was unfamiliar with the stone bridge full of legends and vivid folk stories.
The ancient Zhaozhou stone bridge started to be built in 590 during the Sui Dynasty (581~618) and established in 608.The pioneer for building the bridge was Li Chun who overcame unimaginable difficulties,undergoing all hardships.The location of the bridge is in Zhao County south,Hebei Province.It lay across the Xiaoshui River,far away from the mountains that provided rocky materials.In ancient times,it was such a busy,deep and wide river that could be used as an important carriage to transport heavy rocks and other materials.As we know,no train,no lifting machine could be used to move granite(花岗岩)blocks to the construction site.As an intelligent stonemason and engineer,Li Chun worked out his plan and design all from his own direct observation and investigation.It took his whole life-time in completing the great historical project inChina.Nowadays it is not only a historical remarkable model of architecture,but also a brilliant Chinese cultural crystallization(结晶) of wisdom.
The entire length of the bridge is 50.82 meters with 10 meters width.The whole stone bridge looks like a big bow,the span of which is 37.02 meters,and its height from the top to the surface of water at a regular position is 7.23 meters.The bridge arch seems to be moving smoothly and flatly.The whole arch consists of 28 big granite blocks connected each other tightly together.On both end sides of the general arch there are 4 smaller arches,2 of which on one side,the other 2 on the other side.The smaller arches could be used to decrease the weight of the bridge and save stone materials,and help flood get through easily,which seems to be much prettier.Such a hard-thinking and careful consideration of the engineering article is really a model of design and layout.The span was much wider than the other stone bridge in ancient times all over China.
Today Zhaozhou Stone Bridge is one of international cultural relics and perfectly protected and preserved by the concerned administration of China.
小题1:The best title of this passage is _________.A.Great engineer in ancient China B.Zhaozhou stone bridge C.Four great inventions D.How to build a bridge A.the materials of Zhaozhou bridge B.the structure of Zhaozhou bridge C.the arches of Zhaozhou bridge D.the importance of Zhaozhou bridge A.cart B.transport C.channel D.resourse han20051年前1

慕容蛋蛋 共回答了12个问题
|采纳率100%解题思路:同步卫星的特点:定周期(24h),顶轨道(赤道上方),定高度,定速率.而地球的第一宇宙速度是卫星贴近地球表面做匀速圆周运动的速度.由运动情景可知r越大,v越小,可知同步卫星的速度小于第一宇宙速度.要比较同步卫星的向心加速度和静止在赤道上物体的向心加速度大小,可根据公式:a=rω2,ω相同,半径大的向心加速度大.ABC、三颗星属于地球同步卫星,所以它们的运动速度大小、周期、离地心距离相等,其环绕速度约为3.1km/s,故A对B、C错,
D、同步卫星与赤道上物体绕地球运动的角速度相等,由a=rω2可知同步卫星的向心加速度大,故D错.

Objective the meaning and purpose of human life.A foreign, devoted to the study of "success" research institutions, in one hundred young subjects of the investigation. The study lasted for decades, until the year be in high and vigorous spirits of young people to become fifty or sixty years old frail old man. The results showed that: only one of them is very rich, in addition to the five individual economic security, the remaining ninety-four people are not very good, can be said to be the loser. And that the vast majority of people encounter later in reduced circumstances reasons, not when they were young don't work hard, but their young when not set clear goals.With the goal, people will concentrate on the pursuit of happiness, not to avoid pain. Objective to let everyone morning get up in the morning, there is the passion of the struggle.Clear goals in life is a matter of importance, in other words, is your life ambition, but ambition sounds as a controllable beyond the scope of personal things, and life goals are, if willing to devote energy to do, it may be. Therefore, for individuals, this is what life really want? What do you really want to do? This is your goal, to each of these goals in one sentence. If some of these goals is reaching another step, then remove it from the list, because it is not your goal in life. The target is your life ship compass, grasp it can not detours.Dendrolimus punctatus in pine netting to the nest, this is their common form of collective spin. When dusk, they sally forth in full strength to climb trees, lined up, to eat those juicy pine needle. The caterpillars in the walk, there is a kind of follow each other's instinct, head of walking in front, followed by a caterpillar, orderly, serpentine. Walk in front of the head, while crawling, while continuing to spit out a silk. Wherever it went, silk spit where. To go in front of the pine caterpillar is laying on the road, no matter how far out to the troops, how long does it go, are able to return along the paved road, and not lose the direction.French entomologist Farber, according to the characteristics of Dendrolimus did an experiment. He put a team caterpillar into a large pot, forming a circle, the caterpillar climbed up the pot edge, Farber a pot around the wire off, leaving only the flower pots on the edge of the wire, and put some pine flower pot in central. The pine caterpillar began around the pot edge, receive only blindly go, another circle repeatedly, they think that as long as the Silk Road in, will not lose the. So repeatedly gone days night, pine caterpillars are simply did not know can help food from his a few steps away, eventually because of hunger, fatigue and die.Many people like the pine caterpillar, blindly machinery to spend every day. They are in accordance with the established pattern, every unsuspectingly to live. If asked them why, they might say: "everyone is not the way to live?"This is no goal state of human existence, their life is like losing compass ships, confused, fluttering, not only would never reach the other shore, dangerous and always have a dead, buried in the bottom of the sea.Are important objectives for each person's success, clear goals is like life, the ship's compass. The ship out to sea, with the compass is the first requirement, so the life goal is the first element, and a first step on the road of life.

through a point halfway 这里你应该这样分解这句话去理解
run "from the center of the watch" "through a point" "halfway between the hour-hand and number one"
一条线通过 表的中心 和 一点,那这一点是哪一点呢,就是时针和12点的连线的中点.那两个点就决定了这样一条线,这条线指的就是南方.
2.想象有一条线,这条线通过了表的中心和时针与12点连线的中点.
再完整一点说明好了.这里实际上是一种利用手表指南的方式.将时针对准太阳,那么时针与12点连线的中点与表的中心连线指的就是南方.1年前查看全部

It is known that the compass was first invented in China.
这里是一个主语从句,it做形式上的主语,真正的主语是that the compass was first invented in China这个从句.由于这是一个主语从句,所以that不能省略.
A选项缺少that C选项 语态以及引导词不符 D选项如果改为AS KNOWN TO ALL THAT 才对1年前查看全部
