Sir this is really helpful. I am 2nd year student and revising my first year syllabus with you sir...first I watch your lectures and then mcqs..sir aik request hai ap please 2nd year k AC chptr ke practice mcqs kre buhut h helpfull hoga thank
The duration of 20 oscillation of simple pendulum is measured to be 60 seconds with a stop watch is 0.12 second. Find the un_certainty in period of one oscillation. A)0.2% (B)0.4% (C)0.8% (D)1.2%
Sir object ko hold kar ky move kar rha hy person to horizontal displacement ho rahi hy jabky force vertically lag rahi hy (either gravitational force downward or person holding then upward) to F=mad cos 90 and work should be zero Kuch aor questions hain is type ky kips ki book main where we ignore horizontal displacement while holding something and just consider vertical displacement
Yes initially it was 10m/s then becomes 30m/s which means 3 times it’s initially value v٬=3v put this in formula of kinetic energy then u will get the answer
the correct answer of mcq number 18 will be option d (0 J) as there is no work done on the holded object, the displacement is being covered by the person not the object hence zero work done
Sir May Allah bless you and give you all happy Ness your life 💕 Ameen
Sir Allah give you long life with full success in every moment of life

This lecture really helps a lot
Mcq 29 hack= n(n_1)/2 mgh
n is number of bricks
Thanks alot sir 💜♾️
May allah bless you❤️🥺
Great SR thank you soo much , SR g mara 2 ko test h plz Mary liya dua kejya ga Allah mjhy kamyab Kareen ameen Suma ameen
Sir thanks bundle of thanks.. God bless you .. Face to dikha dy kabiii
mjy chemistry ki discosion ki zarort hai.
my chemistry is very week and i want to improve it..
thank u so much sir
Thank you so much Sir! ❣️
great work
Sir object ko hold kar ky move kar rha hy person to horizontal displacement ho rahi hy jabky force vertically lag rahi hy (either gravitational force downward or person holding then upward) to F=mad cos 90 and work should be zero
Kuch aor questions hain is type ky kips ki book main where we ignore horizontal displacement while holding something and just consider vertical displacement
Nice 👍 👍👍
good job
Kindly upload practise test for all subjects
respected sir hum Q 2 and Q 3 ko 3rd eqution of motion say b solve kr saktay ha na q k wo bhee free fall ka case ha
Good
Sir mdcat se related ziada ziada krwaen piz
Sir this is the practice exercuise what about the self assessment exercise
Please plz plz 2md year ke bhi aese lectures dalein
sir kindly or chapters ki bhi solution upload kar dain
In question 27 the v is 30ms-¹ and how its answer is 270J explain it?
Yes initially it was 10m/s then becomes 30m/s which means 3 times it’s initially value v٬=3v
put this in formula of kinetic energy then u will get the answer
the correct answer of mcq number 18 will be option d (0 J) as there is no work done on the holded object, the displacement is being covered by the person not the object hence zero work done
Assalam o alaikum sir
Sir please tell me why angle between force and velocity and angle between force and displacement would be same as you said in 6th mcq?
Displacement force ki direction m hota h
Agar ap kisi cheez ko saamne se drag karti ho jo displacement hogi wo force ki direction m hi hogi so same direction m hoga or angle zero hoga
In 35 qstn why potential energy does not increase uniformly with time.air resistance to negligible hai🤔
sir q no 18 mein kips acdamey ki explantory notes mein ans zero given hain ??? W= FDCOSTHETA
sicnce angle is 90 between F and D SO W=O
Work w.r.t weight is zero in Q#18
@@PhysicsInSeconds thanks sir
work done by gravitational force on object will be zero on the object
Qu 8 MN sirg apny kha k height 1/4 ho tu kinetic energy 3/4 ho Gai but how plzzzzzz explain sirg
Same question from my side
Jazak ALLAH Sir☺
sir 38 main negative sign nhi hai ////???
Sir...in mcqs ke pdf mil sakhte hai?
Sir ya pdf form ma hn?
I need Mdcat books
is book ki pdf link koi dedy plxzz
sir is k ilawa chemistry ki practice uplaod ho gy?
sir 38 main negative sign nhi hai ////???
