1 次の英文を読んで、あとの (1)~(3)の問いに答えなさい。 Did you know that a lot of people have difficulties in shopping? There are many old people who are too weak and can't walk for a long time. It's very difficult for them to go shopping every week because they can't walk or ride bikes to shops. So, their families want them to stop driving a car. If old people can't get fresh food at a shop for a long time, they will have health problems. In rural places, there aren't many shops near their homes. People can find only a few small shops that are too far away. If old people hope to buy many kinds of things they need, they have to go to bigger shops in bigger cities. But in some rural places, there aren't many trains and buses. So they don't have any means to get there for shopping alone. How about old people living in bigger cities? Cities usually have a lot of shops, but in some cities, people can't find many shops these days. This is because shopping malls are usually built in the suburbs, and the number of small shops *throughout the cities is getting (). So like in rural places, old people have to go shopping in places that are now far away from home. But for some, it's difficult. What can we do for those old people who have difficulties in shopping? Some *vendors carry a lot of products in their cars to rural places or the suburbs and sell them to people living there. If these people can go there every week, local people don't have to go shopping with difficulties. Also, shopping on the Internet is another good way to get things. But many old people have not used the Internet much, so they need other people's support. In the future, there will be more old people in Japan. *Even more people may have difficulties in shopping. So we should keep thinking about the problem. throughout [03 vendor 物を売る人 () means & the suburbs even~ さらに~ (1) 文中の@に次の3つの文を入れるとき, 最も適切な順になるよう符号を並べなさい。 7 You may think that they can go shopping by car.

物体にはたらく力についての問題です。この問題の3と4の解説をお願いいたします。赤ペンで書き込みがあり読みづらいでしょうが、宜しくお願いします。

7 物体にはたらく力について調べるために、次の実験1,2を行った。 表は, 実験結果のうち、ばねの のびを示したものである。 あとの問いに答えなさい。 ただし、ばねののびは、ばねを引く力の大きさに 比例するものとし、糸はのび縮みせず、質量と体積は無視できるものとする。また、質量100gの物体 図1 にはたらく重力の大きさを1Nとする。 図2 【実験】 図1のように、ばねに糸と質量 50gのおもりをつるし おもりを静止させ、 ばねののびを調べた。 実験1と同じばね、糸, おもりを用いて、図2のような装 置を組み, おもりが容器の底につかないようにおもりを水 中に完全に沈めて静止させ, ばねののびと電子てんびんが 示す値を調べた。 1 下線部について, 物体に力がはたらいていないときや, 力がはたら いていてもそれらがつり合って合力が0のときは,静止している物体 は静止し続け, 運動している物体は等速直線運動を続ける。 このこと を何の法則というか、書きなさい。 2 実験2において、水中のおもりにはたらく重力の大きさは何N か 求めなさい。 3 実験2において, おもりを水中に完全に沈めたときに, 水中のおもりにはたらく浮力の大きさは何N か。 最も適切なものを、次のア~オから一つ選び 記号で答えなさい。 ア 0.04 N レイ 0.06 N 0.08 N I 0.10 N オ 0.12 N 4 実験2において、おもりを水中に入れる前と水中に完全に沈めたあとの電子てんびんが示す値を比 べたとき値の関係を述べた文として適切なものを、次のア~ウから一つ選び,記号で答えなさい。 ウ等しい。 ア 水中に沈めたあとのほうが、大きい。 水中に沈めたあとのほうが、小さい。 【実験2】 ばね 糸 おもり 表 容器 水、 電子 てんびん 実験 1 「実験2 ばねののび (cm) 17.5 15.4
