Ответы

Автор ответа: DedStar

Ответ:

μ = 0,1

Объяснение:

m = 320 кг

F = 320 Н

___________

μ - ?

Поскольку снегоход движется равномерно, то сила трения равна силе тяги:

F = μ·m·g

Отсюда:

μ = F / (m·g)

μ = 320 / (320·10) = 0,1

When people staying in a hotel are hungry or just want to relax and have good time listening to music and having a drink, they go to a restaurant or a bar. There is usually a wide choice of beverages there to please everyone. A barman or a wine waiter offers the wine list where the guests can find any drink they ike. For those who don't drink alcohol there are soft (or long) drinks such as juice, lemonade, Coke, mineral water — still or 55 fizzy. Beer is very popular and it can be served bottled, draught or canned. For people who want something stronger there is a great variety of alcoholic (or short) drinks. For example, spirits: rum, vodka, whisky, brandy, cognac. Then come fortified wines: liqueur, port, sherry, vermouth; and table wines dry or sweet, white, red or rose. Guests can also order a cup of tea; coffee, black or white, hot chocolate.
