Поясните различие между динамической и статической работой.

Работа, связанная с перемещением тела или определенного груза, называется динамической. Работа, связанная с удержанием определенной позы или груза, называется статической

Russia ... What do you imagine when you hear this word? Someone imagines a great country that occupies the largest part of the continent, the others think about the largest exporter of oil, another people imagine large industrial cities with factories. I imagine a small village, which is located in the heart of the Siberia.

If you are just passing this village in transport, you can notice nothing extraordinary, but if you take a closer look, you’ll never want to go away. The nature is wonderful there. Clean air, which every citizen dreams about, and the mountains and the forest in the background of the blue almost transparent sky, seem to be fabulous. There are a lotof lakes, where you can fish, go boating or just swim. There are a lot of mushrooms and berries in the forests. Walking along the paths, you can collect a bunch of flowers or just watch and take picture of other ones, which are in The Red Book. Children like to get together and go to the nearest creek to swim in a hot day, and there you can dissolve a fire and bake the potatoes with bacon. And in winter, they build a snow fortress, or take a big horse sleigh; the whole crowds drag them up to the hill and then laugh and go down through the village...

I love the village. Everyone knows you, your parents and grandparents. It seems the village to be a big family... I like "Molodetskie games" most of all. They are always held on Maslenitsa festival. Everybody in the village come to look at them. The teams arrive and the competitions in different kinds of sport take place. They pull rope, then lift weights, sing and dance ... It’s very funny! ... And then people burn a strawman and eat pancakes.

It is often said that a village inhabitant is different from a city man, and I do not deny it. People grown in village are much kinder and they like to communicate with other people. Just because they used to. I think it`s very good, because people are stronger together

Выдающийся русский историк В. О. Ключевский дал очень своеобразное определение того, что происходило после Петра: «Россия отдыхала от Петра». Это определение очень точное. Ведь в действительности не только реформы «переделывали» Россию, но и Россия — реформы. Далеко не все западные заимствования и петровские начинания в силу уровня социально-экономического и культурного развития страны могли быть восприняты. На русской, во многом ещё традиционной «почве» не всё «приживалось». Многое, несмотря на все усилия реформатора, отторгалось. Но ещё больше заимствуемое изменялось, приспосабливаясь к российским условиям — феодально-крепостническим отношениям и самодержавной власти. Обратим внимание на такой парадокс, как крепостная мануфактура, явление, совершенно чуждое для Европы.
