Because of you I passed my mocks you are the besttt W teacher
💅💅

[javedfaizal]

I really appreciate your detailed explanations on these questions may Allah bless you sir🙏

[tayyabbintahir]

Sir is it important to use the words "whrn the sheet cuts the flux" in the magnetic flux question or we can also say that due to the change in flux an emf is produced?

[reuben]

at 39:15 ish but isnt spring 2 compressed?

[lcchen]

hey regarding the sf rule, why is 10b to two sf?is it just stipulated that all answers are to be in 2 sf or whats??

[prodbymyles]

If possible sir could you please explain 11.a)(i) again? I did not quite understand the explanation

[mohammedhalboub]

are you using computer? if yes, what is the program you are using?

[bhoomivalecha]

Sir why did we not take sign convention in Q4 part 1 (s.h.m) ?

[zereff]

Sir do we still have 11 a i in the syllabus (comtinuous energies of x rays)

[saiyarahasanramisa]

Q 9b te, why did we choose the steeper region?

[zainabnasir-op]

Q3b1) how are both springs extending ?? one is contracted and the other is extended so then the direction of the force will be in the same.. please someone explain how the springs have opposite direction

[vmd]

Sir I have a genuine question, why do you cough so much and do that weird phlegm noise

[mubaris.s]

i got brain cancer, can you not use non course related way of equation
