(1)なぜ、ウではなくエになるのかの理由を教えてほしいです 見づらくてすみません🙇‍♀️

これを読んで、あとの問いに答えなさい。 Hi, I'm Kaito. Today, I will talk about Al "devices. We use many kinds of Al devices lik use it to do work given by humans, I think Al devices can make our lives better. There "robots, "drones, and "smartphones, AI devices collect a lot of information, rememberi still a lot of work AI devices cannot do but they can do some work to make our lives easi Through my speech, I want you to learn more about Al devices and to live with them in the future. imagine how It was held by Kamome City At the event, I learned about many kinds of AI devices I didn't know anything about AI devices before I joined an event about them th that can help humans. we ca this summe 9 with her body, it asked her some questions, and gave her suggestions to make her fee better. A man from Kamome City Office said to me, Though this robot can work like doctor, (D). It cannot replace a doctor. But there will be more robots working in hospitals in the future." At the event, I started thinking about the ways to make Al device nt, I started to learn more about AI devices. I've learned that A this graph. It shows the "changes in the number of farmers in 2010, 2015, and 2020 in devices are used in many different ways. For example, AI devices help farmers. Japan and how old they were in each year. The number of farmers became smaller, and the "percentage of the farmers who were 60 years old and older than 60 years old became larger And now, AI devices are expected to be a great help to farmers. After I went to the event, 605799 Look saw graph : グラフ camera:カメラ changes in color(s): 下線部が表すグラフとして Changes in the number of farme ウ 250 (万人) 200 179.8 175.7 150 152.4 100 138.2 50 27A 2010 ° 37.5 2015 C60 years old and older than younger than 60 years old.

One robot I there helped farmers pick tomatoes. The robot has a "camera on it to collect a lot of information about the tomatoes. It remembers the shapes and "colors of "ripe tomatoes and decides when to pick the tomatoes. When it decides to pick the tomatoes, it picks them with its arms. Farmers send the tomatoes that the robot has picked to the stores. At this event, talked with a farmer who used the "tomato-picking robot. I asked him, "What do you think about working with the robot?" He said, "I don't think robots and humans can do all of the same work. But)(2). Today, robots have become very important. The number of young people who want to be farmers has become smaller, because a farmer's work is hard and needs much experience. If robots can do the hard work for farmers, they will improve farmers' lives. I hope more young people will want to become farmers." AI devices are used in our lives in many ways. I've learned that it is difficult for us to live without AI devices in today's world. However, we need to remember AI devices are not perfect. AI devices can remember all the information they collect, but 3). So, we always have to think about effective ways of using them. I hope that more AI devices will be used to help people. AI devices, like the doctor robot and the tomato-picking robot, can improve our lives. So, I want to make AI devices that can work well with humans to make our lives better in the future. That's my dream. Thank you for listening.

この実験2の回路は並列なのになぜ電圧が異なるのでしょうか?

問5 図1のように,部屋の照明のスイッチには,暗い部屋の中でもスイッ チの位置を示すために 「位置表示灯」というランプがついているものが ある。部屋の照明を消すと位置表示灯が点灯し、部屋の照明を点灯する と位置表示灯は消える。 KさんとLさんは, 位置表示灯のしくみについて考えるために, 次の県 ような実験を行った。 これらの実験とその結果について, あとの各問い に答えなさい。 スイッチ 位置表示灯 図1 〔実験1] 2種類の豆電球ア, イを用意し, それぞれの豆電球を電源装置につないで, 豆電球にかか る電圧を少しずつ大きくしていったところ, ある電圧になったときに豆電球のフィラメント がわずかに色づき, その後は電圧を大きくするほど明るくなった。 そこで, 「豆電球が光っ 「た」 とみなす明るさの基準を設定し、豆電球が基準の明るさになったときの電圧を記録した。 その電圧は,豆電球アは1.0V, 豆電球イは 1.7Vであった。 [実験2] 豆電球アを部屋の照明モデル, 豆電球イ を位置表示灯のモデルとして、 図2のよう に、豆電球アとイ, 電源装置, スイッチを つないで回路をつくった。 なお, 回路の各 部分における電圧と電流を測定するため に電圧計と電流計がつないである。 電源装置の電圧を 2.5V にして, スイッ チを入れたとき,切ったときのそれぞれに ついて,豆電球アとイが光ったかどうかを 調べた。 また, 豆電球アとイにかかる電圧 と、豆電球アとイおよびスイッチに流れる 電流を測定した。 表1と表2は,それらの 結果をまとめたものである。 2 (✓ (A) 電源装置 豆電球ア (✓ A 豆電球イ A スイッチ 図2 表1 スイッチを入れたとき 表2 スイッチを切ったとき 豆電球ア 豆電球イ スイッチ 豆電球ア 豆電球イ スイッチ 電圧[V] 2.26 0.09 電圧[V] 0.19 2.14 電流 [mA] 483 61 (X) 電流 [mA] 228 2280
