Hi Mr Ali, Can you please upload October 2023 Unit 4 Physics IAL Paper discussion? I would greatly appreciate it. Thank you.

Sir can u please make a last minute revision or lecture video on Unit 3 for jan 25 students please as your teaching is really understandable to us please sir it would be helpful sir pls

Sir can u pls solve oct 21 and 22 tooo as they seemed hard

Thank yo so much sir, your explanations are truly spectacular and your advice is incredible valuable and accurate!!

Hello sir! I have some questions about calculation. In IAL section B, there are lots of small questions in a big one. When I'm using the result I got from the previous question, I can use the one with rounded significant figures, or I can use the more accurate number. Which way is the correct way? Mean while, the mark scheme usually provides a step by step solution, for example, W=F*S, they calculate F and S separately, sometimes they use the accurate value, while sometimes they use the one with less significant figures, and they even use both ways at the same time, for example F with the accurate value, and S with the rounded one, which may lead to different result by using different methods and it is really confusing. So in the small question, if I calculated parts of the final answer, in the final calculation, which way should I use? Thirdly, the mark scheme sometimes give the final answer even less than the minimum s.f. given in the question's data. Are there a range of answers that can be accepted in Edexcel IAL, or the examiners are really strict? It's a pretty long question, and thank you so much for your patience!

Sir why the drag force on heavier ball is greater ?. Isnt drag force dependent on viscosity, surface area and speed. Please expain this

Sir. for question 11, for earths acceleration, why can i not use 9.8?

Why is q11 not 0.60

Sir do u have online classes for international students for A2 level course

May Allah bless you always sir. Your explanations are so clear and precise.

Dear sir, please upload more papers of edexcel

Thanks a lot sir! Your explanations are really top notch, my IAS is in Jan25 and your videos are helping a lot, could u give some tips on acing AS phy?

Hello sir! I have a question in question 13. The question provided s=2.54m, g=9.81ms^-2, which have both 3 s.f. The answer I calculated is t=0.720s, Is it correct to ignore the last zero, and write the answer in 0.72s, then keep 2 s.f. in question (ii)?

Thank you! Tomorrow mock! Good luch everyone!

Sir, could you plz give the link of the video of graphs?

Sir, Can you provide such video for unit 1 and 2 as well ?

thanks sir , may u go to heaven for these helpful videos

thank you so much helps alot

You are a life savour

can you make this series into a playlist? I cant find it

Amen

You are the best bro keep going ❤❤❤❤🎉😊

I like these bits of wisdom. We all need these reminders since most of us were raied by the Silent generation.

God bless you Sir, this is the exact question that had been bothering me.. The amount of detail and everything helped me cleared my hidden confusions too. Thank you alot sir!

Hello sir! In question 14, your final result of calculation is correct, but I saw on the official mark scheme, the answer is 130m, because the significant figures of the answer should keep the same as the minimum s.f. of the value given from the question. Am I correct? Please answer my question, thank you very much!

hello sir.I wanted to say thank you for these videos. Can you post more years of the ial edexcel papers?

Thank you sir for helping

Thank you so much sir you helped me for my exam

Sir please upload 9702/42/M/J/2024

Aoa sir, for qs 14, it says that: Assume that mixing process DOES NOT CHANGE TOTAL VOLUME of liquid. Does this not mean that whatever the total volume of liquid was before miding process, it will remain same after the mixing process (we are asked to assume it) ... So should we jot take bolune of mixture as 40cm3 ?

Sir why question 13 cannot be C?? And also, do u offer online private tuitons?

U r amazing sir❤

Thank you so much, you've saved my physics grades

Thanks for the the comprehensible explanation, I really appreciate it 😄

Sir in qs 14 , upthrust is equal to weight of sohere and weight of string and probe displaced. Then for formula Fu = pvg It must also give us volune of sphere+probe+string displaced altogether. Reason is that even if upthrust due to string and probe are negligible, it still accounts for the volume displaced by them. Hence we shall only be taking upthrust due to wieght of sphere in order to get the volume of water paryicles displaced bu the sphere (which is equal to volume of sphere submerged) . Why didnt that gavw us correct answer?

❤Superb

This is not a help. This is a social service ❤

I wish i had a teacher like u in bangladesh

💗💗💗

For question 24, why can't we use I = I naught cos square feta So the new intensity is Intensity for 30 degreees × cos²(30)? So the answer is 0.75×Intensity for 30º (Ans C)?

Sir please do jan 2023 unit 4

sir for question 39, why does atomic number stay same? why doesn't it decrease by 4? thank you for video🙏🏾

These are not your own answers, you consulted the answers in the answer section of Cambridge haha😅😂

Amazing

This Q's 8 was disturbing me from soo long. Literally no yt video gave me such satisfying reasoning of solution behind like yours did! You're a blessing!!!! (Kinda felt guilty for not paying you for this ;( .....)

thank u for ur detailed explanation. You’re one of the few couple people who make videos on edexcel alevel physics . I appreciate u ❤

9702/22/m/j/14 sir please solve this
