- Diferencia horaria del dia de la competencia (orlando, November 4, 2012, 23:23)
-
Yo soy de Peru y me he inscrito en al Online Physics Brawl que se realizara el proximo mes, pero tenemos un problema. Yo y muchos de mis amigos porque pensamos que a dicha hora (17:00 a 20:00) todos podiamos, pero ahora nos damos cuenta que la hora de la competencia en nuestro pais es de 11:00 a 14:00 y a esa hora nosotros estamos ocupados (en el colegio).
¿Se han dado cuenta que por la diferencia horaria hay personas de muchos paises que no podran participar? - Reply

- We are very sorry, but we are able to communicate only in English. Maybe we have some organizers who are able to communicate in ?Spanish?, but we are not going to add any other languages to our used ones (Czech, Slovak and English).

Hola (y perdona me que mi espanol no es perfecta
Si es un problemo, pero es dificil de resolver. La mayor parte de los participantes son de Europa entonces nuestro horario es lo mejor para ellos. Tengo una prepuesta: decirle al profesor que es por 'educacion en fisica' y que desea tres horas fuera dela escuela por competencia. En muchos paises profesores son benevolentes con esto. Mucha suerte

- Re: Are you going to translate solutions and series into en (Karel, October 5, 2012, 22:58)
- We are not going to translate it if we have no foreign participants... We are translating the assigments and we are able to correct you solutions and send it back with comments. But since we have in these times no foreign participants, we are not translating full solutions. If we have around 10 foreign english speaking (writing) participants, we would probably start to translate even the solutions...

- Re: Working of parachutes (Dominika, August 17, 2012, 10:11)
-
Hi
if something is falling, gravitational force causes downward motion and drag and buoyancy act upwards. If you consider Newton's drag, it (also) depends on the surface of the falling thing – and parachute certainly has bigger surface than climber himself. So when value of upward forces ís closer to value of downward force, climber achieves terminal velocity quicklier.
This problem has been solved in many books and webpages, you can google equations for describing falling of object in liquid. A similar problem was in FYKOS's series in volume 25, round 4, problem IV.3 Flying stone.
And just for interest, do climbers really wear parachutes during climbing?

Re: Can i get more information about participating in the ca (Dominika, March 1, 2012, 19:15)

Hi,
the camps ale hold twice a year somewhere in the Czech Republic, usually near some village, close to the nature.
We invite usually 25 students who get the most points, to spring camps from 1st – 3rd series and to autumn camps from 4th – 6th series.
Participants have to pay their journey to the locality and they have to pay participant fee, which is usually around 500 CZK.
Participants are usually from the Czech or Slovak Republic, so we speak Czech. In past years we had only few participants from abroad. Some students, mainly the younger ones, don’t speak English very well, it might be difficult for them to have whole program in English, so in that case we had part of the program, like explaining games or lectures, both in English and Czech.
If you would like some more information, just ask

Re: Experimental problem of fourth round (Dominika, February 23, 2012, 16:21)

Hi,
in FYKOS's solutions it is not necessary to solve everything and to have everything right, if you have solved the problem only partially or you only have some idea, you can also send it. You also don't have to send all problems.
So if you do not have kettle, you can just describe how would you meassure or which principles or equations would you use for it; or you can meassure an efficiency for example of a cooking pot. Any idea.would be appriciated

Re: Grades??? (Karel, February 18, 2012, 18:54)

Hello,
I really don't know, how it works in India but (according to en.wikipedia.org/wiki/High_school) I would guess, that you should be in Grade 2. Our Grade 4 matches to the last year of Secondary studies before we start studies on universities. - Reply
