5 6 〔分] (1) 流れる向きが周期的に変化している電流を, 交流という。 家庭のコンセントに供給されている電流は, 交流である。 な お、乾電池の電流のように、一定の向きに流れる電流は,直 流という。 (2) 消費電力が1200 W の状態で使用したときは12A, 消費 電力が600W の状態で使用したときは6Aの電流が流れる。 (3) 600 〔W〕 x 30[s] = 18000[J] (1) 同じ大きさの電圧を加えたとき, 抵抗が小さいほど流れ る電流は大きくなり, 電力も大きくなる。したがって, 抵抗 が小さい電熱線Aのほうが, 電熱線Bよりも電流は多く流 れ 電力は大きい (2) 電熱線Aに流れる電流は, 6 (V) 2[Ω] は, 3 [A] × 6 [V] = 18〔W〕 となる。 これより, 5分間電流 を流したときの電熱線の発熱量は, 18 〔W〕 × 5 × 60 [s] = 5400〔J〕 (3) 電熱線Aに加える電圧を3Vにしたときに流れる電流の 大きさは1.5A なので、電力は1.5〔A〕 ×3〔V〕 = 4.5〔W〕に なる。電力の大きさが1になるので、水の上昇温度も 1/4に = 3 〔A〕 なので、電力 なる。 図3より6Vのとき、電流を5分間流すと8℃ 上昇して いるので,3Vのとき、電流を5分間流すと2℃上昇するこ とがわかる。したがって (0.0) と (52) の2点を通る直線 を引けばよい。 (4) 並列回路では、加わる電圧の大きさは一定なので水の上 昇温度は, ビーカー Ⅰ >ビーカーⅡIである。 また, 直列回路 では, 流れる電流の大きさは一定なので、電熱線Aに加わ る電圧よりも電熱線Bに加わる電圧の方が大きいため、水 の上昇温度は, ビーカーⅣ>ビーカーⅢである。 直列回路全 体の抵抗の大きさは, 4 + 2 = 6 [Ω]なので, 回路全体に流 6 (V) =1 [A] であるから, ビーカー 6 [Ω] れる電流の大きさは, Ⅳの電熱線Bの電力は4W。 ビーカーⅡIの電熱線Bに流れ 6 〔V〕 = 1.5 〔A〕 なので, 電力は9W で 4 [Ω] る電流の大きさは あるから 水の上昇温度は, ビーカーⅡI>ビーカーⅣVである ことがわかる。したがって, 水の上昇温度を大きい順に並べ ると, I > ⅡI>Ⅳ> ⅢIとなる。 図 消費電力が から1つ選び、 何Jになるか。 電熱線 B (4Ω) BAX3V A (① 電熱 熱 電熱 電熱

文章の内容があまり理解できません。 ざっくりで良いので内容を解説して欲しいです🙇🏻‍♀️

About 50 years ago, I lived in Los Angeles, California. My father took care of my younger sister and me. We played baseball every weekend. My sister and I loved baseball. I knew that my father had a "hero. His name was Ken Smith. He played for a team in *St. Louis. Its name was the Red Birds. My father said that Ken was the greatest player of all *major league baseball players at that time. I also became a big fan of Ken Smith, so I wanted to be like Ken Smith very much. That summer was special because my father *took my sister and me to St. Louis. We went there and came home by *plane. We were going to meet Ken Smith. I almost couldn't believe that. My father's best friend had a big *company in St. Louis, and he knew some of the very important people of the Red Birds. He also knew Ken Smith well. We stayed at my grandmother's house in St. Louis, She said to me, "Jack, I have something special for you." That was a ball with an *autograph by Smith. An *injured player of the Red Birds was in the hospital, and my grandmother worked there. She told him my story, and he got Smith's autograph on the ball. She knew that A but she gave the ball to me. I was sorry for my father, but I was very happy. I liked Ken Smith more. The next day was an exciting day for us. My father's friend helped us, and we could meet Ken Smith before the game. I thought Smith would be kind and big, and I was right. Then I showed him the ball from my grandmother. We talked about it. He asked me about the way to practice baseball, and I talked to him *proudly. *In front of Ken, I felt that I needed to do so. I wanted to be a great baseball player. He *understood. That night we watched a night game of the Red Birds. During the game, I *held my ball, and looked at it many times. A man talked to me. "New ball?" he asked. "Yes, with an autograph," I said and smiled. "Who?" he asked. "Ken Smith," I said proudly. "Really? I don't believe you." "Here, look." "Wow! I'll get it for 20 *dollars right now!" "No, give my ball back to me, please," I said. "You've got a very special thing. Take good care of it!" he said. I knew that the ball was a *treasure for me. The next day, 3I felt it took a long time to get back to Los Angeles. I was excited and I told my friends about my experience with Ken Smith in St. Louis. No one believed me, but I thought that I would never forget my happy feelings then. About 20 years later, my father died. Before the *funeral, I *remembered that he once *asked us to put his *baseball cards and a *baseball in his *casket. I wanted to use my baseball with Ken's autograph for him. My sister also liked my idea. The ball was with my father. A few years later, my sister *got married. Before *wedding finished, my sister started a story. She was a *flight attendant and *flew with the baseball players of Los Angeles Blue Sky and the manager Tom Baylor. Then she told him the story of my old baseball. He understood her story very well. Baylor was a friend of Ken Smith and *promised her to get another ball with Ken's autograph for me. Ken *was very impressed by her story, and sent a baseball with his autograph to Baylor. The ball was then sent to my sister. When she finished the story, I looked up and saw that she was holding a ball. "I have B threw it to me. I remembered that summer and my grandmother. I felt like a child again when I was going home. she said and

回 海外で発行されている日本のガイドブックに、漫画とアニメの記事が掲載されています。 記事を読んで、あとの問いに答えなさい。 People around the world now know and love Japanese anime. Some characters are familiar to people who do not usually read manga or watch anime. One of the reasons for this success is the adjustments that were made for viewers overseas Three of them involve titles, characters, and content. 2 Manga and anime titles are, of course, originally in Japanese. Some, like this does not work with all titles. For example, Knights of the Zodiac is originally Seinto Seiya in Japanese. It describes just the main character, but in English, the title was changed to something that relates to the whole story. This made it more attractive to viewers in foreign countries. Characters' names are often changed in manga and anime that are mainly for children. It is hard for children to remember unfamiliar names. With familiar names, children can focus on the story. For example, the character Satoshi in Pokemon becomes Ash in English. The name Ash uses three letters from S-a-t-o s-h-i. Japanese customs are sometimes adjusted for non-Japanese viewers. The adjustments can be small or large. Consider this example of a small adjustment. In anime in Japan, characters eat onigiri. In Western versions, they eat cookies. In manga, they don't change the pictures. Instead they add short explanations. This way, foreign readers can understand Japanese customs and behavior. A large adjustment might be a change in the setting. Consider Kyojin no Hoshi, an anime from the 1970s. In it, the main character Hyuma trains very hard and becomes a professional baseball player. In the Indian version, its main character plays cricket, a popular team sport in India. In short, perhaps anime became more popular because of these adjustments. The language and customs were adapted a little to fit each culture. Think about your favorite manga or anime. The original is probably different.
