蛍光ペンのところの訳なのですが『私は現在ではどんなに不可能に思われても自らの知性を持つ機械人形が考案されるかもしれないことを示そうと思う』であってるか知りたいです！！ どなたかよろしくお願いします🙇‍♀️

パラグラフ5 In addition, Tesla predicted intelligent robots: "I purpose to show that, however impossible it may now seem, an automaton may be contrived which will have its 'own mind." By this, I mean that it will be able, independent of any operator, to perform a great variety of acts and operations in response to external influences affecting its sensitive organs as if it had intelligence. It will be capable of distinguishing between what it ought and what it ought not to do, and of making experiences, or in other words, of recording impressions which will definitely affect its subsequent actions." With the development of today's AI technology, the day when Tesla's prediction of an "intelligent robot" is a reality may come sooner than we think. 加え テス 「私 現在 機械 ( これ 私 操 +6 あ 能 言

（4）がわかりません、なんで運動方程式がF-Nsinθなんですか？Nsinθは小物体にかかる重力の水平方向の力であって、力Fと同じ方向なのに、なんでマイナスになるんですか？(；；)

高校物理の円運動の問題です。 マーカー引きしている箇所で①に③を代入して整理するとSが求められるのですが、 どのように整理したらこの解答に導けるのかわからずおります。 （その過程がわかりません） そもそも代入箇所は、V2への代入でいいのでしょうか？ 教えていただけると幸いです。

問8-3 右ページの図のように,長さlの糸に質量mの物体を結び、最下点で初速度を 与えた。 以下の問いに答えよ。 (1)糸が鉛直方向となす角度が0のときの糸の張力Sを求めよ。 (2) 物体が1回転するために必要なvo に関する条件を求めよ。 この問題では,物体の高さが変わるため, 物体の速さも変化します。 つまり、この問題における円運動は,等速円運動ではないのです。 等速でない円運動の場合でも基本的な考えかたは等速円運動のときと同じですよ。 (1) は「円の中心方向の力のつり合いを考えて, S=mgcose」としてはダメです。 物体は静止していない、つまり,円運動をしています。 円運動をしているということは,中心方向に加速度が生じていますよね。 加速度が生じているということは,力のつり合いではなく, 運動方程式を立てて考えなければならないということです。 <解きかた (1) 向心力は、張力Sと, 重力の中心方向成分である-mgcoseとの和 S-mgcos 円運動の半径はlなので、運動方程式F=maにあてはめると v2 S-mgcosQ=m ………① F a 献により、 また、物体は最下点から高さl (1-cose) の位置にあるので 力学的エネルギー保存則より 1 mvo=mgl(1-cose) + -mv² 2 位置エネルギー 運動エネルギー 最初の運動エネルギー ・③ 問題文にない』を消去 Onie? ②より,v=vo2-2gl (1-cos) ①③ を代入して整理すると, 求めるSの値は 2 S= mvo l + mg (3cos 0-2) 答 ......④ ちょっと難しく感じたかもしれませんが使ったのは運動方程式 (①式) と, (①式)と、 力学的エネルギー保存則 (②式)の2つで、 ①式が円運動になったというだけです。 「円運動でも使う道具は今までと同じ」と考えておけば怖くはないですよ。

7 S 2 Topic, should campanies be required to produce goods that are easy to recycle? Some people say that it is not necessary for companies be required to produce goods. - that are easy to recycle. On the other hand, 3 < others say not. I agree with the latter idea and have two 6 reasons why I think so. First of all, I will explain that from point of view of pollution. , Receatry, it is matter that a lot of things c. which can not recycle increase day by day. and the place where collect garbage is a becoming full in Japan. 12 Therefore, in order to make the world better, If it is important to recycle easily. 15 16 17 8) 20 21 22 Second of all, I will explain that from point of view of company profits. To clarify this, if the company use goods. that are easy to recycle, they can reduce costs to import a lot of materials. It will lead to increase Custmer's income. According to the reasons mentioned above, Companies should be required to produce 2 goods that are easy to recycle. 23 136

5 UNIT3 Reading Passage 10 15 20 20 25 30 Listening When important events are happening around the world, most people turn to traditional media sources, such as CNN and BBC,¹ for their news. However, during the invasion of Iraq by the United States and its allies in early 2003, a significant number of people followed the war from the point of view of an anonymous² Iraqi citizen who called himself "Salam Pax" (salam means "peace" in Arabic, and pax means "peace" in Latin). Salam Pax wrote a diary about everyday life in Baghdad during the war, and posted it on his web site. Pax's online diary was a kind of web site known as a "blog." Blogs, short for "web-logs," are online diaries usually kept by individuals, but sometimes they are written by companies and other groups of people. They are a rapidly growing type of web site on the Internet. There are estimated to be several hundred thousand blogs on the Internet, and with the popularity of other social media sites, the number of people writing online about their lives continues to grow. may find A blog differs from a traditional web site in several ways. Most importantly, it is updated much more regularly. Many blogs are updated every day, and some are updated several times a day. Also, most blogs use special software or web sites which are specifically aimed at bloggers, so you do not need to be a computer expert to create your own blog. This means that ordinary people who computers difficult to use can easily set up and start writing their own blog. In 2003, the Internet company AOL³ introduced their own blogging service, enabling its 35 million members to quickly and easily start blogging. There are many different kinds of blogs. The most popular type is an online diary of links, where the blog writer surfs the Internet and then posts links to sites or news articles that they find interesting, with a few comments about each one. Other types are personal diaries, where the writer talks about their life and feelings. Sometimes these blogs can be very personal. There is another kind of blogging, called "moblogging," short for "mobile blogging." Mobloggers use cell phones to take photo's, which are posted instantly to the Internet. When the content and images posted online involve news subjects, mobloggers become citizen journalists. In fact, the Korean web site OhMyNews was a well known source for articles from international citizen journalists. However, in 2010, OhMyNews stopped posting new articles. Instead, it is now a blog site where citizen journalists can choose what makes the headlines, or just share ideas about how regular people are changing the news world. Anyone who visits the web site of a big media company can clearly see how the idea of blogging has changed the reporting of news. Quite often, a list of reader comments follow news articles. It seems that the news is becoming less like a report or a lecture, and more like a conversation, where anyone can join in.
