Ответ:

Объяснение:

Fупр - сила упругости (пружины, упругого тела...)

"-" минус - сила противодействует внешней силе

k - коэффициент упругости (приложил силу F и растянул или сжал на 1 метр {Н/м})

x - удлинение (сжатие) в метрах

L - длина

Δ - (дельта греч. буква) означает разность чего-то (Здесь означает разность длин конечной и начальной пружины L-Lo)

sunkarsaulet: С обоими можно найти Fупр да?

The Reading Test
Read about this piece of England in China, then do the test.
The building company Hong Kong Housing is building a new suburb in Shanghai, a city with a population of more than 16 million people. But this suburb is not like other parts of Shanghai. It is a little piece of England. The name of the new area is "English Town". The manager of Hong Kong Housing, Shi Guangsheng, says many people in this area of China want to buy an English house and live in an English town.
"This town is like Bristol or Chester. There is an English square and there are pigeons to feed like in Trafalgar Square, London. There are four English-style pubs and you can buy English beer to drink. There is a canal and you can row a boat there like in Cambridge."
Are there any cricket fields? "No, there aren't any places to play cricket because nobody in Shanghai can play this game. But there is a football stadium like those in England. And the thing we are very proud of is our shopping street. There are several shops where you can buy traditional English food like fish and chips or Christmas Pudding."
