5. Длина нерастянутой пружины 4=10см. Под действием силы, модуль которой F1=4H, пружина удлинилась на ∆/=2см. Определите длину 2 пружины, если на неё подействует сила, модуль которой F2=6Н.

Ответ:

Для решения данной задачи воспользуемся формулой закона Гука:

F = k \* Δl,

где F - действующая сила, k - коэффициент жесткости пружины (измеряется в Н/м), Δl - удлинение пружины.

Сначала найдем коэффициент жесткости k1 для первой пружины:

k1 = F1 / Δl1 = 4 / 0.02 = 200 Н/м.

Теперь найдем удлинение второй пружины под действием силы F2:

Δl2 = F2 / k1 = 6 / 200 = 0.03 м.

Таким образом длина второй пружины будет равна:

l2 = l1 + Δl2 = 0.1 + 0.03 = 0.13 м или 13 см.

Many young people complain that they are not given enough help by those people who should be helping them most- adults! 'I can't understand it,' says 15-year-old Hayley Lomas, 'Adults have all been teenagers at some point so they know how it feels. But instead of understanding, sympathy and support in getting through this difficult time, we often get criticism.' Hayley isn't alone in thinking this, but there are, of course, many adults who do want to pass on their experience and knowledge. In fact, some of them have now set up a website and mobile phone app called Daily Respect to do just that. So how does it work? 'It's easy!" says Geraint Tillotson, the man who started Daily Respect, the organisation that provides the app and website. You download the app and then you get a daily message through the app about an issue that's important for many teenagers. If you then want to find out more, there will be a link to the relevant section of our website which will give much more detail about the subject. Daily Respect contacted over a thousand teens to get their ideas on which subjects to cover before they even started the site, and now ask their app and website users to email them ideas for other topics they could cover. The most popular area of the site are the pages about relationships, explains Tillotson. But problems at school including bullying are not far behind. An area that's growing fastest are probably the pages about problems online - you know, cyber-bullying and abuse on sites like Facebook. The site and messages aim not to judge young people but to provide simple, practical information to help them make good decisions and so get as much as possible from life. 'We aim to supply information so that teenagers can make their own decisions, free of other peoples' opinions,' says Geraint. 'No advice is given, just information, so we won't tell you what you should do - we will give you the tools to mans cituations yourself or with support
