Here is the qualifying (remote) round of the physics Olympiad «Formula of Unity»/«The Third millennium». We will be happy if your friends who like physics also participate. However, every assignment should be done individually; otherwise, your submission will not be considered.
Rules of the qualifying round
The qualifying round is an online-test: for each of the problems you have to give only the answer. You can find the instruction for participation in the previous post below.
The winners of Olympiad 2020/21 (those with Diplomas I‑III) can participate directly in the final round.
You can send your questions (about both the problems and the participation) to the organizers by e‑mail firstname.lastname@example.org.
