Объяснение:

Дано:

m = 300 г = 0,3  кг

F = 2Н

Найти: μ - ?

Тіло рухається рівномірно, значить сила тертя дорівнює силі тяги:

Fтр = F

F =μmg

μ = F/mg = 2 / (0,3 * 10) ≈ 0,67

PRIMARY AND SECONDARY SCHOOLS IN ENGLAND
Schooling in England is compulsory for all children from 5 to 6 years old. Besides, they
can continue their schooling and have two more years of school studying. In England, the
primary education is up to 11 years old.
First, children enter an infant school and then move on to a junior school (which is often in
the same building) at the age of 7, and then, when they are 11, go on to study in a
secondary school. About 90 per cent of children receive their secondary education at
«comprehensive» schools where children of all backgrounds and abilities are educated in
a single school.
For those who wish to stay on, а secondary school can include the two final years of
secondary education, sometimes known in Britain (for historical reasons) as «the sixth
form». In many parts of the country, these two years are spent at a sixth-form college,
which provides academic and vocational courses.
The academic year begins in late summer, usually in September, and is divided into three
terms, with holidays for Christmas, Easter and for the month of August, although the exact
dates vary a little from area to area. In addition in each term there is normally a mid-term
one-week holiday, known as a «half-term».
1) English children can choose when to start or finish their schooling.
2) Some children stay at school at 16 for two more years.
3) Infant school is a stage of primary education.
4) Children who study at «comprehensive» schools have special abilities and talents.
5) The two final years of secondary education are traditionally called «the sixth form».
6) English pupils have no holiday in spring.
