What I did not like the choices appear. ozone generator A long time ago I was taught that the adhesion force is responsible for leaving traces of pencil on paper and chalk on the blackboard. Or how to use friction to explain why modern students of trail markers remain on a fairly smooth surface whiteboards.
I'd ozone generator call it a "trick" question. Did it well defined and always the same, and the answer may be only 2.5 hours or 2.5 hours, but many students gave a response common in life, 2h 30min, and wrong. The key was relentless 0.5 points for value and 0.5 points for the unit.
Even two tasks for 1 point. Both good and bad. Good for those who do not know how to solve tasks - losing just one point. Bad for those who know the task - there again some may prescribe a number of values of A) 144 B) 5 and that's it. Bad teachers, because we have no insight into how children work tasks.

You should have two questions on key ON, 1 MV and LV 1 and sent to the competent ozone generator and Table standards that are checked. The drafters of the tasks in physics, apparently have minded interpretations ... As I recall, geography is not checked advanced level. Interesting to student achievement in physics in the school where I work: 13 53% 14 33% (other ozone generator written 2:30), 15.9% (determined razultantu and not read to require acceleration and mass written as a solution of 1N!) And 16 7%.
Thank you for your help colleagues. ozone generator I looked and it's ozone generator more or less it.
