5 A Matter of Taste Reading Passage 042 At the age of just 22, Jamie Oliver became well known across the UK as "The Naked Chef." He called himself this not because he cooked wearing no clothes, but because he wanted to simplify food preparation so that everybody could follow his recipes. He wanted to "strip down" the idea of cooking. Since then he has had numerous TV shows, published 50 many books, and has become a household name in the UK. Today, one of the activities Jamie Oliver is best known for is his great effort to improve the school dinners that children eat every day. One day, he visited the kitchen of a typical London secondary school, and he was shocked to see how much processed junk food the kids were given to eat each day. Fat and sugar levels were extremely high, and nutritional values very 10 low. The "turkey twizzler" became the symbol of these unhealthy meals: processed meat containing 21.2% fat and only 34% actual turkey. Oliver ran the school kitchen for one year and tried to show that it was possible to serve healthy meals on a limited budget—and that kids actually enjoyed eating them. His mission was to radically change the eating habits of children in that school, and across the country. 150 200 15 20 25 CULTIES 250 His project (the "Feed Me Better" campaign) has had some influence on school dinners in the UK. After watching the documentary Jamie's School Dinners, 271,677 people signed a petition calling for healthier school meals. This led the Prime Minister to agree to spend 280 million pounds (about 37 billion yen) on school dinners, to ban some junk food from school menus, and to create a School Food Trust to provide support and advice for people preparing school meals. Research, by the way, shows that children who stop eating sugary, fatty food and instead eat Oliver's school dinners are better behaved in class, and they get higher test 300 scores, too. 350 Of course, the project has had some problems. At first, many students (and even parents) resisted the removal of the junk food they were so used to. In one famous instance, some parents were passing local takeaway food to their children through the school fence. Also, schools that followed the plan for a while were often found to gradually drift back into bad habits. After all, it is easier and cheaper to just give the kids junk food. However, Oliver's efforts represent a positive start, and with obesity becoming such a huge problem (see Unit 4), 400 it's a very necessary start.

3. Answer the following questions. 1 What is the difference between UNIX and Linux? 2 3 4 Choose one of the words in italics in the text. What is the definition of the word you have chosen? What are the three levels of a Linux system? What are the two main functions of the kernel? [Reading Text] UNIX was initially developed by researchers at Bell Labs in the 1970s. Today, UNIX and its variants are widely used mainly on servers. By far, the most well- known UNIX-like operating system is Linux. Linux is available in different distributions which include the Linux kernel and different collections of software. These distributions have various user interfaces, many experienced users preferring the command-line interface, or shell. Linux distributions include a range of software including text editors. memory. While the mechanics of Linux and other Unix operating systems are complicated, the components of a Linux system can be grouped into three levels. The lowest level is the hardware, such as Central Processing Unit (CPU) and The next level is the kernel. It enables communication between hardware and software, by providing instructions to the CPU and other hardware. The programs that are running on the system, or processes, make up the top level known as the user space. Processes in user space generally only have access to a restricted amount of memory and operations, this is called user mode. The kernel runs in kernel mode which allows it unrestricted access to hardware resources. The kernel provides functions such as process management and memory management. A computer only has limited Random Access Memory (RAM) and processor cores. Process management allows the system to run multiple programs (processes) at the same time even if the CPU can only execute only a few processes at a time. Memory management allows applications to share the system's memory while avoiding potential issues such as memory leak. Included with the kernel are device drivers that provide an interface for applications to communicate with hardware, such as hard drives. System calls allow user processes to access features that are executed at kernel mode, for example creating new processes.

6は5よりq=0になりました。 合っているか教えて欲しいです。 5.6が不安です!

原点 0 を中心とし、 厚さを無視できる、 半径 & の導体球殻 A と A より小さい半径 l2 ( l1 > l2) の導体 球殻 B のふたつの導体球殻上に分布する電荷が作る静電場について考えたい。 初めは、 導体球殻 A に電荷量 Q を与え、導体 球殻 B には 電荷を与えない状態にしておく (下図左側参照)。 その後、ふたつの導体球殻を導線Lでつなぎ、その結 果、初めに導体球殻 A にあった電荷のうち電荷量だけが導線L を通って電流として流れ、 導体球殻 B へ移動して静 止した状態になったとする。 ただし、 電荷の移動後においては、電荷は導線L上には分布せず導体球殻 A から B へ電 荷量αの電荷が移動しただけで、 いずれの導体球殻にも新たな電荷は与えないものとする(下図右側参照)。ふたつの導 体球殻上の電荷分布が作る静電場E'(r) は、 球対称性より、 l₁ B Q と書くことができ、 導線Lによる球対称性からのずれは無視できるとして以下の間に答えよ。 ただし、 r = |r | は、原点 から任意の位置までの距離であり、E'(r) はr=|r| のみに依存する求めるべき未知関数である。 また、 rを半径とし て原点を中心とする仮想的な球の領域をV、Vの境界をなす球面を Sとし、導体球殻と導線以外は真空で、真空の誘電 率を co とする。 なお、 r の値によって分類する必要がある場合には明確に場合分けして解答することとし、 問6は、 問 1から問5 までに対して正確かつ明確な導出が記述されている場合にのみ採点対象とする。 0 O l₂ 基礎物理学B 第2回レポート問題 Tº A E(r) =E(r) T T l₁ B Q-9 q O A l2 L ア 1.位置rにおける球面 S上の外向き単位法線ベクトルnを、rとr≡|r | を用いて表せ。 2. 球面 S を貫く電束を計算し(積分を実行すること)、未知関数 E(r) を含む形で表せ。 3. ふたつの導体球殻を導線Lでつなぐ前の状態における未知関数 E(r) の関数形を求めよ。 4. ふたつの導体球殻を導線Lでつないだ後の状態における未知関数 E(r) の関数形を求めよ。 5. ふたつの導体球殻を導線Lでつないだ後の状態において、 導体球殻 A と導体球殻 Bの静電ポテンシャルの差 A-B を線積分によって計算し、gを含む形で表せ。 6. 導体中での静電場の性質を考慮して、 g の値を求めよ。
