75 day challenge day 3

Chem did 20 adv lvl qs nd 20 nk integers

Maths 36 mains lvl qs nd 4 normal qs(did to make it 40🥀)

Phy did 10 adv qs on angular momentum

Total 90

Gng plz help me with angular momentum concept applications like ik the concept but idk how to apply it in qs ,nd when to apply?

Suggest me some nice videos on angular momentum (preferably <3hrs,but isokay)

And why do some qs get easily done by energy conv but not with angular momentum conv ?

Nd doing kinetics till adv pyqs enough right.?

Physics 🥀

okay this is a good conceptual q i think if you really understand it

good solve

soln -> since rod can't provide force on any other dirn than x axis the normal from ground is 6mg (the hinge type shi won't experience any force)

b) momentum cons (let vel of ball be v when ball reaches bottom most pt)

mv=6mu

v=6u

energy cons

2mgl=mv²+6mu²

2gl=v²+6u²

21u²=gl

rt gl/21 =u

now if you observe from inside the cart you will see that the ball is performing circular motion w velocity 7U

and there's no need to applying psuedo force here cuz the tension on the ball doesn't accelerate the cart at this instant

radial accln

T-mg=m(49u²)/l

T= m ( 7g/3)+mg

T=10mg/3

so Normal rxn -> 6mg + 10mg/3

28mg/3

Need proper advice that is my marks trajectory stagnant

the first test is the jee adv ppr conducted at allen dlp recently .the next tests are of the coaching that i study in aakash , and the last image shown is the first jee mock i ever gave. i feel like my trajectory has become stagnant and i just cant improve as the chapter compile

hello guys i am in 11th can you please explain if this method is reliable or not for physics physics goats help me

  1. i am using physics galaxy completely for physics and not solving my allen modules because i did nlm from them and i felt my nlm was weak but as i used physics galaxy my 5 volume wali it improved my mechanics will end this week and i havent done modules yet but solving physics galaxy and mains pyq

2.what i am doing is solving physics galaxy illustration and exercises along will all mains pyq on marks app i will solve all back exercise (when my mechanics about to end that is from next week)

total question in pg are around 330-350 per chapter (all questions included) and mains pyq around 150-200 per chapter on marks app

  1. is this method relaible for class 12th

thanks for your help

also i will solve adv numericals after my mechanics end as i found them having multiconcepts of different chapters

Day 26 of worshipping hours

Aaj mene 75 pyqs kare like a chad 😼(35 physics and 40-45 maths idk)

Phir mene pg ke examples kare like a good boy maja aa gaya plus back pain ho gaya

Lowkey bahut dard ho rha hai

Periodic table phir se revise karli

Btw soon one month hone wala hai is series ka ek lamba post daalu ga uspe ki kya improvement hua aur stats kya aaye itne dino me

75 challenge day 1 nd 2

Yesterdays update

Chem attempted a adv like test (18q)

Nd another 25 mains like qs

Nd another 50 cuz why not🥀

Phy did 20 hcv qs nd read concept

Maths did 10 mains qs nd read concept

Total 133

Todays update

chem did 30mains lvl qs nd 20 nk integers

Phy did hcv 10qs nd read concept nd did another 10qs

Maths did 30qs nd read concept

Total 90

Dont call me a larper gng ,i go to 7 to 9 coaching🤡 so this much is reasonable 🥀

Day 25 of worshipping hours

School + coaching (7+6=12hrs)

School me chem ki module ka s-1 and 2 kiya (quantum aur periodic table):- approach 80 questions

School me periodic table bhi yaad karli 😈

Illustrations from pg 7 aur sir ke class ke illustrations around 10

Btw mere vo 75 questions daily wale ka resume

Bino Bino 🙆🏻💁👁️👁️👁️

drop your solution and it will be helpful if u explain it

also it will be more better if you attempt this in zike format manner and tell your time

also u can type in which attempt you got the answer ✌🏻

Quality post(Guys can you tell the niche topics which you have read and are extremely helpful in jee but are not a part of syllabus like Pappus Guldinus theorem in physics)

Thanks for helping please segregate the maths physics and chem portion and also metion chapter if possible

these damn determinants

seriously how tf am i supposed to express this as a product of two determinants in as little time as possible

it took me like 15 minutes to do this one question that's a serious waste of time on a question thats not even hard or worth spending that much time into

are there some tricks or speed is just smth i pick up after multiplying determinants a lot

DAY-2 OF 75 Questions Daily Challenge

https://preview.redd.it/jxyij5dil1kh1.png?width=1366&format=png&auto=webp&s=e700467bf9ce79b8cceb60c33627bac4f19124f6

So, I somehow managed to complete the target yesterday. I was feeling quite sick and had to sleep, so I wasn’t able to post my progress at night.

Also, I’ve seen many people start this challenge, and honestly, it makes me really happy to see so many of you taking it seriously. I genuinely appreciate everyone who decided to join and push themselves. Keep going, stay consistent, and most importantly, be honest with your progress.

“Excellence is not an act, but a habit.” — Aristotle

Let’s keep going. Best of luck to everyone! ❤️

random qs ranging from jee mains to imo,ipho,ico difficulty is chosen random, DAY- 4

since nearly no one even attempted the qs i have made some changes there will be 2 problems now one will be the easier one which is helpful for jee and 2nd the hard one qs which can wasily put you into depression so happy solving and try to attempt both no matter where you get stuck
