Объяснение:

m=Vp (p плотность стали = 7800 кг/м³)

F=mg (сила тяжести)

g = 9,8 Н/кг

m= 2•7800=15600 кг

F = 9,8•15600= 152880 Н

A. why Barbara came to England
B. what surprised Barbara most of all in Notting Hill
C. Barbara’s friends’ images of England
D. Barbara’s discoveries about the English
E. what Barbara knew about Britain

1. “My turn,” said James. “Next game: you’ve got a time capsule and you want to put one thing in it which represents England. What do you choose?”
“A Number Seven Manchester United shirt,” said Ben. Number Seven was the shirt worn by David Beckham, who was Ben’s personal hero.
“That just represents England now,” argued Barbara. “How about a cup of tea?* she suggested.
“No,” said James. “No one drinks tea any more. Everyone drinks cappuccino.”

2. Barbara looked at her friends. There she was in London with a group ofj Londoners, playing games. She was the first person in her village to go toj England and her parents were very proud of the scholarship she had won which! enabled1 her to study at the University of Westminster in London. Her college] was right in the middle of London.

3. Before she arrived, Barbara had thought that she knew everything about] England. She had watched every film about England from her local video store.] She’d watched the film Notting Hill seven times; she couldn’t wait to meet Hughj Grant or some other Englishman who looked just like him. She’d also seen The\ Full Monty, which showed that there were villages in England, a bit like those at home. But The Full Monty, however, was set in Sheffield and her English] teacher had told her that Sheffield was in the North of England. There was aj north-south divide, he told her. Barbara wondered what the north-south divide looked like. Perhaps it was a bit like the Grand Canyon in America, but smaller.]
4. It had been a shock arriving in Notting Hill and finding that apart from1 the Russells, the family she was staying with, most of the other people in the street were black. Notting Hill, she soon discovered, was a centre of Afro-Caribbean culture. When she first arrived she realised that despite2 her good marks in English at school, she didn’t understand a word anyone said. The Russells were very nice and introduced her to some of the neighbours, who were English with West Indian parents. Barbara discovered, that in fact they spoke more clearly than lots of the white people she met and they were very friendly.
5. One day Barbara met Ben and his friends who met up most evenings to go for something to eat or to see a film.
The English are strange,” said Ben one afternoon.
"Yes,” agreed Barbara. Later that night, back in her room, she took out a pad of paper.
“Strange things about the English: Number 1,” she wrote.
“There are some things that are bad, which you may talk about, and some things, which are good, that you may not talk about.”
She had discovered that you mustn’t talk about how much money a person earned, but you may talk about how much money a person spent. In fact, the English students talked about money all the time. You may, also, talk about falling in love but not about getting ill or dying. In fact, considered Barbara, students in England generally didn’t want to talk about anything serious. Barbara had told her friends about her list and soon they were all making suggestions.
“Whenever the English come back from abroad they always say what a lovely time they’ve had and how friendly everyone was. That’s because they don’t expect3 people to be friendly, because they aren’t friendly to outsiders,” said James.
“No,” said Barbara, “everyone’s been really nice to me since I got here.”
