НА ПЛОЩАДИ 200 СМ В КВАДРАТЕ ДЕЙСТВУЕТ СИЛА ДАВЛЕНИЯ
Дано
S=200 СМ^2=0,02м^2
F=2 кН
p-? p=F/S
p=2000H/0,02м^2=200000/2=100000Па=100кПа

BAKU9491: а если ответ в МПа , то будет 0,1

ramit08: ДА ДА!!!!!!

Автор ответа: kirills1

p = $\frac{F}{S}$

F - сила ( 2 кН = 2000 Н )
S - площадь ( 200 см² = 0,02 м² )

p = $\frac{2000}{0,02}$ = 100000 Па = 100 кПа

Помогите с кратким пересказом текста Teenagers.

We spoke to six 16-year-olds from around the world to find out what they and their friends like to do in their free time. Here's what they had to say.

Fiona, 16 Galway, Ireland

"I've got lots of friends and we’re all into the same kind of things. We like watching TV, especially comedies and my all-time favourite is Father Ted. We love music too, and I'm really into indie bands like The Bravery and the Arctic Monkeys. I try to go to as many gigs as I can. I'm not really into fashion. I can't stand shopping and I couldn't care less about designer labels."

Josie, 16 Glasgow, Scotland

“I really like shopping. I think it's a relaxing, enjoyable pastime. So much so, I can spend hours window shopping in the city centre with my friends. H&M is my favourite clothes shop because you can always find great bargains there. I also like going to the cinema and I try to catch a film at least once a fortnight with my friend, Tom. Everyone my age is crazy about mobile phones and texting has become a new national pastime!"

Jamie, 16. Crystal Brook, Australia

"I live with my family on a farm near a small town in South Australia. The countryside is beautiful around here and I go walking and horse riding a lot but life is generally boring. I don't fancy living here when I'm older and dream of going to live in a big city. My friends and I spend a lot of time on the Internet playing games and chatting and we watch DVDs. Of course, like all teenagers, we always have homework to do."

Kim, 16 Vancouver, Canada

"During the week I don't do much in the evenings apart from my homework, so I really look forward to the weekends. On Saturdays, I usually hang out with my friends down at the shopping mall where we check out the shops for new clothes, grab a bite to eat and watch a movie. On Sundays, I usually go for a trip to the countryside with my parents. I love that."

Brandon, 16. Seattle, USA

"I'm an active person. I hate TV. I find sitting in front of a TV screen a waste of time. I'm fascinated by the great outdoors. I'm a skateboard fanatic and get to and from school every day on one. At the weekends, I try to get out of the city and go rock climbing or paragliding. Extreme sports are my passion! I think it's important to look good too and I go for the sporty look."

Emily, 16. London, England

"I like keeping fit, buying expensive clothes and dance music! I love going out clubbing with my friends at the weekends - we dance all night. I have two younger sisters, but we fight a lot because they always want to wear my clothes. That's so annoying - I hate it when they do that!"
