Перша з трьох однакових металевих кульок має заряд -10е, друга - +2е, а третя не тральна. Чому дорівнюватиме заряд кожної кульки, якщо другою доторкнутися спочат до першої, а потім - до третьої?

McDonald’s



The hamburger has no connection to ham. It got its name from the German town of Hamburg, which was famous for its ground steak. German immigrants to the United States introduced the “hamburger steak”.

At the St.Louis World’s Fair in 1904, hamburger steaks were served on buns for the first time. Hamburgers on buns were convenient and tasted food. This became the usual way of eating hamburgers.

How did the hamburgers become the most popular, most typical American food? The introduction of the bun is an important part of the answer. Another important part is McDonald’s, the fast-food restaurant.

The first McDonald’s restaurant was opened in San Bernardino, California, in 1949. Hamburgers were the main item on its menu. People liked the restaurant’s fast service. By the 1960s there were many McDonald’s restaurants. McDonald’s was a part of nearly every community in the United States. There were also fast-food restaurants that sold hamburgers. McDonald’s alone sold millions of hamburgers a year.

Today, of course, there are McDonald’s restaurants around the world. The food they serve is considered typically American. And, although McDonald’s has expanded its menu, the main item on that menu is – as always – the hamburger.

The hamburger is fast food consisting of a fried patty of minced meat, usually served in a bread roll. About 4 million hamburgers are eaten each week worldwide.
