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?
basically if number of turns and area is constant, emf is direclty proportional to B/t. since B/t was the gradient of the graph, and steeper means greater gradient, we chose that. so we'll get the max emf. hope i was right :)
Hey! The actual rule is, you should use the same number of significant figures given in the question. If you’re given 2sf as well as 3sf, you need to give your answer to 2sf(the minimum number that’s provided). There are some anomalies though, like this variant. Time was 100, that’s 3sf. But, the answer was given to 2sf, 0.020. For cases like these, it doesn’t really matter. If you did write 0.0200 you’d probably still get marks. But most of the data is usually given to 2sf, so thats the easiest way to do it, unless you wanna be a perfectionist!
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

Love your videos! Physics has been my worst subject but now I'm gaining more confidence in it thanks to these videos
You got this!
u got this myles 💪💪💪
@@nyareay__1970 best wishes Nyareay!🙏🏽🙏🏽
This video was so helpful thank youu much.
Because of you I passed my mocks you are the besttt W teacher
💅💅
I'm so glad! Major W. We take these
I really appreciate your detailed explanations on these questions may Allah bless you sir🙏
It's my pleasure
If possible sir could you please explain 11.a)(i) again? I did not quite understand the explanation
Is eddy currents in our course?
yea niggaaaa
not really, u can always write current instead of eddy currents
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?
Yeah, just write "when the sheet cuts the flux" (As long as you write cut) to be safe in my opinion.
@@zestyolu8413 thanks
Sir why did we not take sign convention in Q4 part 1 (s.h.m) ?
Because it is what it is
at 39:15 ish but isnt spring 2 compressed?
nah, they were expanded from 12cm to 18cm in the beginning, remember?
Q 9b te, why did we choose the steeper region?
basically if number of turns and area is constant, emf is direclty proportional to B/t. since B/t was the gradient of the graph, and steeper means greater gradient, we chose that. so we'll get the max emf. hope i was right :)
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??

are you using computer? if yes, what is the program you are using?
Yes! One note for windows.
THE BEST EVERRR!!!!!
No u ❤️
bless u fr
i bless u too
Sir do we still have 11 a i in the syllabus (comtinuous energies of x rays)

bhai apni goated
very goated
no you guys are the goats
goattt

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