Hi. Taras,
Well, spring officially starts in March, summer in June, autumn in September and winter in December. But sometimes we have weather from each season all in one day. Because English weather changes so often, there is always something to talk about A remark to a stranger about the weather such as "Not a very nice day, is it?" can often lead to an interesting dialogue
Even poets talk about the weather. For example, the great poet Lord Byron (1788-1824) once said, "I like the weather, when it is not raining. That is, I like two months of every year."

Для начала переведем в СИ: 500 г = 0,5 кг Распишем силы, действующие на брусок. Это сила трения скольжения, сила тяжести, сила реакции опоры и сила тяги. Т.к. движение равномерное, то ускорение отсутствует. Согласно этому запишем 2-й закон Ньютона: Fтр. + Fт. + N + mg = 0 Запишем проекции сил на ось X(она обозначена красным): Ox : Fт. - Fтр. = 0 Fт = Fтр Fтр = μN Выразим N через ось Y: Oy: N - mg = 0 N = mg Подставим это значение в формулу, указанную выше: Fт = Fтр = μ*m*g Выразим μ: μ = Fт/mg μ = 2,5 /0,5*10 = 0,5 ответ:0,5
