Alr so first off, for those wonderin - yes, @Dasht-Escape-Alt is me.
Second, some news about the NPUA, as per tradition atp smh smh - exam results came in. If they don't make my grade lower for no reason, THE ABSOLUTE LEAST im getting is a 30/40 (13 from math, 17 [speaking of HOLY SHIT that's so low??? I didn't think i'd get anywhere below 18??? How the fuck did i let that shit happen?????] from physics) (outta 20 each). After the բողոքարկում bullshit, im probs getting a 31, and if im lucky, a 32 (question 14 from physics i "got wrong" but i really can't see where i went wrong... i remember the question by heart, it's gonna be at the bottom f the post - if u know what went wrong PLEASE let me know.). In the end, i think im for sure getting in fo free, especially since the 34/20 mark isn't really real.
Third, i got an mp3 player (i think? something adjacent to it at least, hopefully ts works)!!! It cost me a lil more than 5.5 buckaroolinos and honestly im rlly lucky i even found it. I went around basically the ENTIRE city center and NO STORE HAD AN MP3 PLAYER. I went into tech stores, into convenience stores, dollarstores, random bullshit stores, old bullshit stores, random kiosks by the side of the road, YOU NAME IT, IVE BEEN THERE. I even went into Zovq, SAS, Eureka and a fucking game zone basement, NO ONE HAD ANYTHING OR KNEW WHERE IT WAS SOLD. Even the biggest tech store close to home, Eldorado (the one on northern avenue) didn't have one. Even this random ass old tech store where we often go to do XEROX n shit didn't have one. I went around foot for 4 fucking painful dehydrated hours and in the end, BARELY found something remotely similar to an mp3 player, originally meant for cars n shit. Now i need to get an SD card and put songs there and pray it works. I can't even walk well today cuz of how much i walked yesterday, i was DYING by the time i got home istfg
No i won't order one online, i dislike ozon, wildberries and i am NOT FUCKING SETTING FOOT IN TEMU. I'd rather die. Same with alibaba, and we don't have Amazon here (well we technically do but the delivery will cost more than the entire country's fucking gdp and it will arrive in november 2093) (ouuu shiii look at these rhymessss 👀 put a container in the fridge, das a cold case)
Anyways uhh yeah das pretty much for the time. Have a nice day folkz
OH and the physics question:
2 connected vessels, each having a surface area of 20cm^2, are filled with water. On top of both, weightless platforms are placed, and in one of the vessels, a 160 gram body is placed on top. After placing that body, by how much (in cms) did the water level in the other vessel rise?
My solution:
M(body)*G/S(vessel) = ρ(water)*G*h
0.16kg*10/0.002m^2 = 1000kg/m^3*10*h
0.16*1000/2 = 1000*h
0.16/2 = h
h = 0.08m = 8cm
But the answer sheet says the answer is 4cm, which I have NO clue how they got. It doesn’t even make sense, the values don’t match up:
Height * surface area * density of water) * gravity should equal mass of the body * gravity
0.04*0.002*1000*10 should equal 0.16*10
But after simplifying, we get 0.04*2 = 0.16 which is absolutely not true, so I don’t get if I’m stupid or are they just wrong
