3 Jill, Ellen, Bob, and Edward lived near a lake/They could go for a swim every day. A man named Mr. Black lived near the lake, too./Sometimes Mr. Black went swimming with the children. One day they asked him to go for a swim with them./Mr. Black said "We can't go for a swim. We may never swim in the lake again." "Why not?" asked Edward. "Because the lake is polluted," said Mr. Black. "There's a new sign at the lake. It says No Swimming, Polluted." "What is polluting the lake?" asked Jill. "Let's go down to the lake and look at it," said Mr. Black. (ア) Mr. Black and the children went to the lake on a sunny Sunday. They looked into the water. It wasn't clean/They walked around the lake and they saw why it wasn't clean. “Look at that *garbage in the water," said Jill. "That's what's polluting the lake.” Edward saw oil floating on the water./"That oil pollutes the water, too,” said Edward. "It comes from boats on the lake." "Come here," said Ellen. "Take a look at this. There are tires in the lake !" "Why would people throw tires into a lake ?" asked Bob. "They just don't stop to think," said Mr. Black. "But they are not the only ones who pollute the lake. The people who run that factory pollute the water, too." Bob looked at Mr. Black/"What can we do? How can we stop the pollution ? he asked. "Well, we must get help from other people. We can't do it alone," said Mr. Black. Mr. Black had a friend who worked for a newspaper company. He asked him to help. The next day the story about the pollution was reported in the newspaper. Many people read about the story. They talked of the pollution. They talked of ways to clean it up. people met at the lake./They came to clean it up./ They cleaned out the garbage. Then they cleaned out the tires./They set up big cans. Then they put signs on the cans. The signs read, "Put Your Garbage Here." /People who lived near the lake came to help./People who had boats came to help./And, people from the factory also One day (イ) came to help. They knew that it would take a long time to get the lake clean again. But they did not give up. They all hoped that someday the "No Swimming” sign would come down and the people could swim in the lake again. 注) 〒garbage=ごみ

中2⌇理科⌇電気 についての質問です. 画像の問題が本当に全く分かりません,, 分かる方 教えてください ❕ お願いします🧁♡̷

Kさん 電熱線の長さと抵抗の大きさにはどのような関係があるのですか。 先生図5は、ある電熱線を表しています。 図5と材質も断面 積も長さも同じ電熱線がもう1本あるとすると, 2本の電 熱線の抵抗の大きさは同じです。 図6のように,この2本 の電熱線をつなぐと抵抗の大きさはどうなりますか。 Kさん 1本の電熱線を図7のように表すとすると, 2本つない だときは図8のように表すことができます。 あっ、これは 直列回路となっているので、電熱線を2本つないだときの 抵抗の大きさは、電熱線1本の抵抗の大きさの2倍となる のではないでしょうか。 表 電熱線の長さ[cm] 電流の大きさ [mA] 3 800 6 500 8 (2) O 016310 電圧計 先生そうですね。 電熱線の材質も断面積も同じとき、電熱線の抵抗の大きさは電熱線の長さ ① に比例することが知られています。 -+ 実験 2 (1) 材質も断面積も同じ電熱線を切って, 長さが3cm, 6cm, 8cmの電熱線3本を用意した。 (2) 抵抗の大きさが4Ωの抵抗器cと長さ 電源装置 が3cm の電熱線を用いて, 図9のよう な直列回路をつくり、 ある電圧を加えて 回路に流れる電流の大きさを測定した。 (3) 6cmと8cmの電熱線についても(2)の 操作を行った。 このとき加える電圧の大 きさは実験2を通して一定であった。 |結果 2 JARD 長さが3cm, 6cm, 8cm の電熱線を用 いたときの結果をまとめると、次の表のよ うになった。 ただし, 8cm の電熱線を用 いたときの電流の大きさは、省略してある。 図6 抵抗器 c 図8 図5 スイッチ SEN ERR 図9 3cmの電熱線 図 7 AW 電流計
