15*10/(15+10)=6    6+4=10       10*15/(10+15)=6 Ом

U=I*R=5*6=30 B

P=I*U=5*30=150 Вт

My relatives live in Lousiana,the USA. They are widlife specialists. They care for otters: there are a lot of them in Lpusiana. They prepare the otters for life in the wild. Some otters are sold to zoos. But most of the animals go to states where otters have disappeared. When I visit my relatives I help them to care for otters. I love otters. I feed them, I clean their cages. My uncle says that he is happy that the otters are coming back. I am also very happy. I think it is necessary to help wild animals. Now I know I want to work for a widlife park

Напишите, пожалуйста транскрипцию русскими буквами
Holidays are the most pleasant time of the year for most children. They can forget about school subjects and relax, doing whatever they want. In my country the most important holidays are New Year, Victory Day, Easter. My favorite New Year's holiday, because we have two weeks of vacation. I can stay at home all day, watch my favorite TV programs or play with friends. I celebrate this holiday at home, with my friends and relatives. We also give each other gifts. Personally, I like giving gifts to other people, because I think it's great, because I can make them happy. In conclusion, I like the holidays with which they unite people
