In question 1 b(ii) it's asking distance covered in time interval of 4 seconds so it's 4.2. other then that ig stilll not a bad thing for concepts ig so
Yes. The only thing which matters here is that the tube has an open and a closed end so you must have a node at plate end and an antinode at the transmitter end. The answer here should be the shortest distance between two adjacent nodes because they are intensity minimum. Hope it's clear to you now.
If you want us to solve for you a specific paper, please send your request here examhelpweb.com/subject-requirement/ and you will hear from us shortly.
The question says that the ball reaches terminal velocity in free fall. As air resistance acts on the ball while it falls, its acceleration decreases, which is why that equation cannot be used. The 4 equations of motion can be used only when acceleration is constant.

2:49 we’re only asked to find the distance in the first 4 seconds
yeahh
My bad, the final answer would be 4.2m.
Q1 b ii) is wrong, its supposed to be 4.2
thank you bro

your voice is very sweet !
For Q4(b)(iii) 1
If we drew some other waveform and subtracted them would we get the same answer?

amazing video
thank you so much
Haii your way of working is very nice but i could suggest for you to slow down a bit in your explanation😄
theres a reason why youtube added the option to reduce or increase the speed
@@shahzaibali6815 slow down means slow down lmfao . They r referring to speed. She already gives a good description
Can you please also do the solutions of may June P23 2021???

But1(b is wrong they asked for O to 4 seconds not 12
Oops! My bad! For the first 4 seconds, it covered a distance of 4.2m as calculated above.
question 2b part 2 is incorrect should be 33.98
That is accurate, although you only need an answer corrected to 2 significant figures. That will be 34.
the value of acceleration due the gravity is 10 not 9.81 right. my teacher says both can be accepted in exam@@examhelpweb2090
For 7:00, why cant we use v2=u2+2as?
The question says that the ball reaches terminal velocity in free fall. As air resistance acts on the ball while it falls, its acceleration decreases, which is why that equation cannot be used. The 4 equations of motion can be used only when acceleration is constant.
Thanks a lot💜💜✨
Thank you
Can you please upload or send the pdfs for P2s?
Would be thankful

Hi izzat
Ma hoon maryam
Qn 4 iii. 2 why you divided by 4🤔
I assume you mean Q4 b iii part 1. The 5/4 essentially means 1 and a quarter of a wavelength, 3/4 mean 3 quarters of a wavelength.
THAAAAAANNNNNNKKKKKK YOOOOU
