I forgot the formula that gives the final temperature from the given quantities, and then I used the ratio to find the final value. Since the mass of the added water is greater, the final temperature should naturally be closer to the added one's temperature. I first took the ratio of the masses...

There is water in a cup (which thermally insulated) with 75 °C of temperature and the mass of water is 0,25 kg. Then we are adding 20 °C and 0,35 kg of water into the cup. The heat capacity of water is c = 4180 J/kgK. What is the temperature of cup in the end? I found it 40 °C but I feel like I...

Welcome between us, Raza!

I'm preparing for the olympiads in Türkiye, because I can not apply IPhO before passing the Türkiye exams. İt's name is "TUBITAK-2202 science olimpiads"

That was great and technical, thank you soo much for giving the information, I'll check them all.

So we can't assume the thing like that. got it

I'll check the course you mentioned, thanks

If we assume that dark matter interacts with mass, according to Einstein's general theory of relativity, the presence of mass will bend the fabric of space-time and thus dark matter into curves. So, can we suggest that this matter, which occupies a large majority of space, behaves like a very...

Hi, I'm a high school student and I want to get accept to Oxford University, so I need a strong self-history for UCAS motivational letter, and I think the Olympiads must be the correct door for it. Could you guys give me some advice for physics Olympiads? What topics or lectures should I go...
