@@examhelpweb2090 no you have not you just gave the answer without any explanation which is really annoying as we can also find answers from the mark scheme
@@examhelpweb2090 Cmon .....B.I.T.C.H..You're Way Of Teaching Really Sucks...You really just paste the whole marking scheme and you speak in FORCED ENGLISH ACCENT which makes it way worse...Mostly you're answers are wrong so please do Check Them At Least Once..😒😒😑😑😤😤😤😤

@@noobthroughs2285 bro just cuz I knew the answer doesn't mean I looked up the marking scheme, I only point out the mistake but the creator gave explanation dummy.
Length is directly proportional to the cross-sectional area or r^2 and area has radius squared which is why when radius doubles, length increases by 4 times.
Q2 iv why are we considering only tension as the force on the wire ? Don’t you think that weight of the block would alsohave an impact on force on wire ?
Stress involves force that is being experienced by the object which causes a change in that object. Here because of the weight of the block, the wire experiences tension hence tension is that force that causes stress and strain in the wire.
The first wavelength= x and the second one is 170nm less than x. Ratio of the second to first wavelength is already given so use that ratio to find the value of x. Hope it's clear to you now.
You solve just like you are explaining yoyrself not others please expalin in depth so your videos will fet more helpfull
dude what is this we know how to read a question and and copy the ms too explain the question
Misleading , without proper explaination !!
dont waste your time here guys....
Can you please give somemore explanation of the questions you solve☺️☺️
We are giving explanations to questions in our videos.

In Q1 the resultant velocity shud be from the aircraft velocity in still air in the right side north of west and then to get 115 degrees 180-65
Yes that was a mistake there thank you for pointing that out.
U r just pasting the ms answers 🥺
Kindly tareka sa explain ka answer dan.. we have ms but not explaination
why are we substracting it from 180

Why does length increase by four times if area is doubled?
Length is directly proportional to the cross-sectional area or r^2 and area has radius squared which is why when radius doubles, length increases by 4 times.
Misleading.. can’t u just check ur answers before sharing them. Q 1ii the angle is 115

u hav made a mistake in the first question its supposed to be cos 115
Thanks for the correction!
why tho?
Resultant bhi Galat banaya and wrong angle taken
Worst physics video I have ever watched 👎
2:14 U r just writing from the marking scheme without even checking the calculations.
can you please explain why she says the block rises first before decreasing? at 3:29
i didnt understand Q5a ii)
where did 680nm come from? can you explain in a little detail please? 😊
The first wavelength= x and the second one is 170nm less than x. Ratio of the second to first wavelength is already given so use that ratio to find the value of x. Hope it's clear to you now.
@@examhelpweb2090 thanks a lot
For 4B if how wud u calculate phase difference if wave Q and Wave P had different time period ?
you cant
if u cant explain dont do videos
