Oblicz rezystancje dla obwodu o nątężeniu 60mA i napięciu 0,3V .Bardzo proszę o pomoc

wzór R= $\frac{U}{I}$

jednostki [Ω= $\frac{V}{A}$ ]

ognien Rezystancja = napięcie nad natężenie (wszystko jednostki podstawowe :))

I = 60mA = 0,06A
U = 0,3V

R = 0,3 : 0,06 = 5 (Ohm)

Odp. Rezystancja ma wartość 5 Ohm.

POMOCY ! PILNE! Read the text and decide if the statements are true (T) or false (F). 1 Tara has never joined Facebook. F 2 Tara thinks a friend is a person you spend time with in the real world. 3 The girl who was bullied didn’t go to school for a long time. 4 Tara never communicates online. 5 Katie doesn’t use Facebook very often. 6 All Katie’s e-friends are from the same country. 7 Katie uses a false name online. 8 Katie is careful about the images she posts. To network or not to network We ask two teenagers for their opinions of social networking. Tara I know I’m not typical but I’m not very keen on Facebook. I signed up to it last year but I don’t go on the site very often. Some people at school say they have hundreds of ‘friends’ but this is silly. How can someone you have never met be your friend? My friends are the people I see every day. They really know me and they really like me. That’s the important thing. I also think these sites can be a bit dangerous. A girl in my class had a lot of problems with online bullying. People were posting nasty comments about her and telling lies. She was very upset and missed a lot of school. I love my computer and I use it a lot. I email my friends or chat to them online. But then we arrange to meet face to face. You can say a lot more! Katie I go on Facebook every day, sometimes several times a day. I love it. It’s fun to see what other people are doing and to look at their photos. I have about 250 friends, some of them abroad. I don’t care that I won’t meet them face to face. We can still enjoy chatting. People say you can have problems with social networking. It’s true that you need to be careful with your security settings. Privacy is important too. I don’t give my real name or my address online. I always use a nickname. I’m also careful about photos. If I want friends from school to have a copy, I send it directly to them. I don’t post a lot of pictures of people online. I know the difference between my real friends and e-friends. And I still enjoy communicating online with lots of different people. It’s just good fun.
