What's reason behind writing copper hydroxide in q. No. 5 e I need a valid explanation
bro slow down i can't see a thing 😭😭😭
I have a question here: for Q5 (e), why does the new wave is exactly twice the original frequency? As it says gradually increases, why can't it be tripled or so?
Thank you❤❤❤❤❤❤❤❤❤❤❤
Very well explained. Thanks a lot!
I dont understand no3. You said the angle of incidence is 37 degrees(the critical angle) but to answer the question on why red light doesn't change direction, you said "angle of incidence is 0"
Dear teacher , it would be helpful if you could give the timeline
Did you mean time stamps? They are in the video description.
@@examhelpweb2090 my bad, didn't notices before
24:26 why is it not destructive interference?
To answer this question, it is important to realize that a series of maxima and minima will be observed along the path of detector and not just at spot X. As the phase difference now changes to 180 degrees, this will produce maxima (from constructive interference) and minima (from destructive interference) switch spots.
Thank u
in number 9 y did u use 390
I didn't have to. You can pick any value from them graph and find the time taken for it to reduce by half the amount.
u dont answer or reply to ur comments i did not get no 9a)iii properly
In this question you can find the half-life by the time taken for count rate to reduce by half. You begin by subtracting the background count rate (which is due to background sources and not from the radioactive sample itself) from any value from graph, find its half then add back the background count. Lastly find the time for the change from your first chosen count rate value and your final count rate.
35:54 it is 0.12 not 1.2
Right, thanks for pointing that out. I'll add this to the description box.
you don"t even explain anything, all you do is just write the answer. useless
For qs 2(e), how come its ionic bonding ane covalent bonding? Can u explain to me? Tq if it said react exothermically with water, its always covalent bonding? For qs 3(c)iv, why the product u write is NH4CL ?
In Q2 e, most importantly oxide of E conducts electricity only in molten form. This indicates the ionic nature of compound. The exothermic detail from water reaction could possibly be due to hydrolysis of metal chloride. Recall that enthalpy change of hydration is negative. The reaction in Q3 c (iv) is hydrolysis and memorizing the key products will be helpful.
@@examhelpweb2090 ok thanks 👍
Explain the reasons why you chose this formula in q5 ...or think about it from a student's point of view as a student I would try to use f=ma then m is given but how would I find f and in f how would I find v (sorry to say it feels like you are just reading the ms)
hi could you please change the title to paper 21 oct/nov 2023 from paper 23 may/june 2022? it gets confusing when i was looking for p23 mj 22 not 21 on 23
Thank you
3:33 just because its not found in the laboratories?
How canu find the phase difference if they didn't have the same time period? If anyone understands please help 🙏😭
I appreciate that thanks
Please help cannot get the right answer in dopplereffect question
The denominator shifts to left HS of equation and gets multiplied by 4870. Then subtract the V terms and divide 30681 by 20.
maybe you are great explaining and solving in 30 minutes
3b should be sin(60) not cos(60) when you use sin(60) it will give you 3.197..... and round to 2SF gives you 3.2
worst physics video ever! no explanation, no steps, just rushing like a damn fool
Thanks, this was helpful
tysm for this!
can you explain question 4 further?
Which part of it ?
Thanks for your effort ❤
Watch with 0.75 x playback speed
Thanks ❤❤❤
if u cant explain dont do videos
Hi. I don’t understand how you get the percentage in question 2(a)?
It is a fact for memorisation. Just like percentage of CO2 and other gases
Very poor explanations, just off the ms without any further reasoning as to why the solution is that.
bad didnt explain at all
For 14:50 why did your graph end specifically there. Because it also says so in the marking key. So why is that?
When the gradient increases four times, the new graph will have a sketch such that each x coordinate will now have a y coordinate that is 4 times that of the initial graph. As a result of this where previously 16x units correspond to F1, now (16/4=4 ) 4 x units correspond to the same y coordinate.
Hi for 7b iii) why is the answer different when we use V^2/R as the resistance would be the same?
Worst physics video I have ever watched 👎
for the 4th qn, can we have the independent value as angle of slope being elevated?
whats the point of making a video if you dont even know what you are doing yourself and you're just copying off everything from the mark scheme? do you think we don't have access to the mark scheme? we can see all the answers too, we're viewing your video to see the explanation but if you just read off the mark scheme to try get views that's just the same thing as scamming. you're just wasting off people's time too
Great work love from Bangladesh 🇧🇩❤
Atleast she is trying to help us
This is for offensive some people in this chat Instead of telling the creator to do better why don't you guys open a UA-cam channel and try to explain better by yourself
For question 2 why don't we calculate power as rate of work done?
That's because in this question you are already provided with applied force and velocity. You do not need to find work done.
Everytime there must be a tricky part to a question or a caching point, i like physics but i don't understand why it's like that, sometimes i get discouraged 😢
It might seem difficult now, but practice makes perfect! Keep working on it and you will definitely see improvement👍
@@examhelpweb2090 thank you 😊
thank you so much
how you know phosphorus + chlorine makes white solid how u know its white colour
It is a fact for memorisation.
WRONG Q4 AND Q5!!!
how to get 5/4 in Q6 c
Starting from d which is point S and then to be able to draw as accurate slope, I have broken the distance S to T down to four parts, d at S, 5/4d, 3/2d, 7/4d and then 2d at T. All these diameters are along the wire length. The division is just to make it easier for you to plot on the graph.
Shouldnt the start and stop Codons also be multiplied by 3
A codon itself is a combination of 3 bases so there is no need to multiply.
THANK YOU SO MUCH
