решение. 1. ri=2*r; rii=r/2; ri/rii=4; не надо ни о какой площади сечения говорить. два куска проволоки содинили последовательно, получили ri=2*r; два куска той же проволоки соединили параллельно, получили rii=r/2; ну, а теперь раздели первое на второе!
а теперь общий случай: ri=r*n; rii=r/n; ri/rii=n^2; кусок проволоки разрезали на n одинаковых кусков. сначала эти куски соединяют последовательно: ri=r*n; затем соединяют параллельно rii=r/n; ну и дели первое на второе и делай выводы.
I like having my supper in the family circle. When all members of the family get together in the evening I feel relaxed and comfortable. Yesterday I had my supper with my mother, father and elderly sister. We were sitting at the kitchen table enjoying a delicious meal. We had mushroom soup, to begin with, then my mom served a vegetable salad. I have always loved that kind of salad, where sliced cabbage and carrots are mixed thoroughly with adding some sour cream and salt.
Then we had boiled eggs, fried meat with mashed potatoes and we drank tomato juice. The portions were small, we never eat too much before going to bed. But this time we were offered a special dessert, - my mom had cooked an apple tart, so none of us could refuse such a seductive treat.
So, it was a wonderful supper on a quiet evening, I was sitting next to my sister drinking tea, biting small pieces of the tart and talking to my family members. We were talking about our daily routines, remembering all the interesting events that had happened during the day. Then, when we finished eating and talking I helped my mom to get the dishes done. After that I went to bed, I was happy, relaxed and in a good humor, so I fell asleep very quickly.
