Scientists **complain about noise **pollution. It damages animals, plants, and people. animals and plants need beautiful music. But they don't like big, *4terrible noises. 学習日 9) The Magic of Music 音楽の不思議な力カ 1 The history of music is very old. People all over the world have always loved it s there anyone who doesn't like music? Probably the answer is no. Music is one of the most necessary things in life. Maybe people can't live without music. Do animals and plants like music, too? Do they understand music? 5 2 Oneday Mrs. Evans read a very interesting story in the newspaper. A *1 "university professor found out that her plants became stronger when music was played for them. At first she thought thatit was a joke, but she wanted to try it 2) herself. She built two rooms in the garden and put the same kind of vegetables in both rooms. The temperature of the rooms was the same and both of them were very quiet. Music was played in one room. The other room was silent. She was 3) 10 surprised to find that the next day the vegetables that she played music for became taller than the ones in the silent room. 3 In the United States, there was a farmer who kept many cows. The farmer was very interested in music. When he stayed at home, he always listened to music on the radio. One day he took his radio to the farm. When he was *2milking his cows, 15 the radio was playing beautiful music. He found that the cows gave more milk *than 1usual on that day. He wanted to know the reason, and three months later he 4) learned that he could get more milk when the cows listened to beautiful, quiet music. 4 Today many scientists say that animals and plants also enjoy music. Like Us, 20 *4 *5 They say that we must think about many kinds of noises we are making every that We day. 1 313 words I

(ii)ではAC=2(r++r-) と書いてありますが、これは(i)でも言えますよね？((i)での半径をr+、r-とするとです。)そしたら半径比って(i)でも(ii)でも同じになってしまうのではないかと思いました。 なぜイオン半径比で安定な構造かどうかが分かるのでしょうか？
