The resulting data were used to construct a graph of load as a function of elongation, from which it was possible to obtain the spring constant of the spring. In addition, for one value of load the spring was given a small additional stretch and released, thereby setting the system into vertical oscillation.
Finland is a bilingual country. Finland has two official languages, Finnish and Swedish. Both these languages have a long history in Finland. Approximately 90 per cent of Finns speak Finnish as their first language and roughly 5 per cent speak Swedish.
There is a much more comprehensive e-book, by the same author: Introduction to Finnish. The Finnish language, spoken mainly in Finland but also by people of Finnish origin in Sweden and other countries, belongs to the Fenno-Ugric group of languages, which is a part of the Uralian family of languages.
