m=210 мг;

k=1,12 мг/Кл.

Знайти І.

m=k*I*t, звідси знаходимо струм, який проходив в електролітичній ванні:

І=m/k*t=210/1,12*216=0,87 A.

Сambridge University
Cambridge University is the second-oldest university in the English-
speaking world (after the University of Oxford) and the seventh-oldest in the
world.
The story of Cambridge University begins in 1209 when several hundred
students arrived in the little town of Cambridge after having walked 60 miles from
Oxford. These students were all churchmen and had been studying in Oxford at
that city's well-known schools. It was a hard life at Oxford for there was constant
trouble, even fighting, between the citizens of the town and the students. Then one
day a student accidentally killed a man of the town. The Mayor arrested three other
students who were innocent and they were put to death. In protest, many students
left Oxford, some of them went to Cambridge. And so the new University began. It
was Cambridge University. Of course, there were no Colleges in those early days
and student life was very different from what it is now. Students were of all ages
and came from anywhere and everywhere. Life in College was strict. Students
were forbidden to play games, to sing (except sacred music), to hunt or fish or even
to dance. Books were very rare and all the lessons were in the Latin language
which students were supposed to speak even among themselves.
In 1440 King Henry VI founded King's College, and other colleges
followed.
Nowadays there are more than 30 different colleges, including five for
women students and several mixed colleges, in the University. The number of
students in colleges is different: from 30 to 400 or 500.
There are many ancient traditions that are still observed at Cambridge.
Students are required to wear gowns at lectures, in the University library, in the
street in the evening, for dinners in the colleges and for official visits. One more
tradition is to use Latin during public ceremonies of awarding degrees.
All the students must pay for their education, examinations, books,
laboratories, university hostel, the use of libraries. The cost is high. It depends on
college and university speciality. Very few students get grants.
Many great men studied at Cambridge, for example, Bacon (the
philosopher), Milton and Byron (the poets), Cromwell (the soldier), Newton (the
outstanding physicist), Darwin (who is famous for his theory of evolution) and
Kapitsa (the famous Russian physicist).
What is the second-oldest university in the English-speaking world?
When was the University of Cambridge founded?
How many colleges are there at the University now?
What ancient traditions are still observed at Cambridge?
Who studied at this University?
