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

■ 音 写真の3,4番の問題の解き方を教えてください!

4 音の性質について調べるために,次の実験を行った。 1~4の問いに答えなさい。 図 1 〔実験1] 図1のように, 弦Aの一方の端を壁にねじでしっ かりと固定し, 三角形をした2つの木片と滑車を通 してもう一方の端に物体Pをおもりとしてつるした のち、2つの木片の間の弦の中央をはじいて音を出 し出た音の波形をオシロスコープで観察できるよ うにした。 〔実験2〕 弦Aと物体Pのほかに, 弦Aと同 じ材質でできていて太さが異なる弦B と、物体Pと質量が異なる物体Qも用 意して、表に示したような条件 ①~④ で弦をはじき、出た音のようすを比べ た。図2は、表の条件 ① ではじいたと きに出た音の波形を模式的に表したも のであり,横軸は時間を, 縦軸は振幅を示している。 表の条件①と条件② で弦をはじいたときの音の波形 を比べると、図2の長さXは,条件 ② のときのほう が条件①のときよりも短くなった。 また, 条件②と 条件④で弦をはじいたときの音の波形を比べると, 0.01秒 図2の長さXは条件②のときのほうが条件 ①のとき よりも短くなった。 なお、図2の長さYについては、条件 ①~条件 ④ ですべて同じ であった。 1 下線部の結果から、条件 ② で弦をはじいたときに出た音の高さは、条件① で弦をはじいた ときに出た音の高さと比べてどのようなちがいがあったことがわかるか, 簡単に書きなさい。 2 表の条件①ではじいたときに出た音の振動数は何Hzか,図2から求めなさい。 3 〔実験2]の結果から考えられることを, アーカからすべて選び、その記号を書きなさい。 ア 弦Aは弦Bより細い。 イ 弦Aは弦Bより太い。 23 ② -4- 弦A A 滑車 Q B B ウ物体Pは物体Qより質量が大きい。 オ条件①のときは条件 ② のときより弦を強くはじいた。 カ条件②のときは条件 ④ のときより弦を弱くはじいた。 4 次の まるものをア、イから一つずつ選び, その記号をそれぞれ書きなさい。 表 条件弦物体 2つの木片の間の距離 P 30cm Q P Q - 30cm- ・木片 物体P ねじ、 X 30cm 図 2 30cm 30cm 10 弦A 物体Pは物体Qより質量が小さい。 は,〔実験2〕について, 生徒が先生と交わした会話である。⑩~にあては 生徒: 条件 ①~条件では,どれもちがった音が出て興味深かったです。 先生: そうですね。 〔実験2では弦の太さと弦につるす物体の質量を変えましたが, 2つ の木片を動かしてはじく部分の弦の長さを変えても、出る音は変わってきます。 そ れでは、図1の装置を使って最も低い音を出すにはどうすればいいと思いますか。 生徒: 弦 [アA [B] に物体 ⑥ [ア P イQ〕 をつるして、2つの木片の 間の距離はできるだけⓢ [ア 長く イ短く] すればいいですか。 先生: そのとおりです。 実際にその条件で弦をはじいて確かめてごらんなさい。
