9 Ампер

Объяснение:

$\frac{1}{R} =\frac{1}{6} +\frac{1}{12} =\frac{3}{12} \\\\R=\frac{12}{3}=4 Om.\\\\I=\frac{U}{R} \\\\I=\frac{36}{4}=9 A.$

On 10 May 1933 students from the Wilhelm Humboldt University in Berlin took books from their university library and burned them. They burning lasted for hours, and thousands of books were thrown into the fire. The students were not punished or expelled from the university for this. Over the next few days a lot of other German universities followed their example. The writers who Germany didn't need anymore were Albert Einstein and Thomas Mann, Sigmund Freud and Jack London, Ernest Hemingway and many others.The book burning was a part of Nazi propaganda. They declared that Germany should burn anything which was not German and destroyed the German spirit and culture.A century earlier a famous German poet, Heinrich Heine, had said: "Where they burn books, they will soon burn people." By 1933 his words had been forgotten, but seven years later millions of people were burned in concentration camps.A new generation of Germans do not want to make the same mistakes again. Every year on 10 May they celebrate Book Day. They know that they mustn't forget.

People have been travelling for thousands of years. A lot of books are written about courageous travellers and their adventures.Travelling was rather dangerous in the old days and merchants (купцы) who sent their ships off on long trading voyages never knew how many of them would return.

It's much easier to travel nowadays. A lot of people, business people especially, prefer travelling by air to travelling by cars or trains. It saves time, and time is money.

As for mc, I try to avoid travelling by plane since I get arisick. I also don't like travelling by sea. The train is the one means of transport I really enjoy. Two years ago, wc went to Vladivostok and it was a pretty long trip, but I enjoyed it very much. We passed many different regions, and the passengers could enjoy beautiful views. When the train stopped at the little stations, we were offered some local food: berries, fish, pics, and some unbelievably tasty boiled potatoes.
