HOW WAS PHYSICS PAPER 2 AS!!!!!!!!!!!

[AppleGreen]

ITS 1000Hz for sure.....people who r telin 500Hz made mistake in cm to m conversion.....ma whole class got 1000hz ...abt 56 students...LOL...still 500hz people thnk its wrng??lmao

dude thr is solution in the first few page

tha
thank god ahmed! you again have increased my confidence mine was the same oh yessssssssssssssssss

how many SFs u all put?

My mistake on the young modulus question, u guys are correct i mixed up da axes

but C is a big value something to 10^9

something like that.
everyone got that

Mr lamao distance between two nodes was 0.34 m and in a STATIONARY wave distance between two nodes is lambda/2=0.34 m.Now prove how i am wrong

wavelength was in cm not m

no the answer of another guy is right

wavelength was in cm not m

So?i converted it into m for everyone if u want me to show u in cm i can

you must have forgot that in question it was mentioned 2.5/m/x10^6

my KE was 1. something and PE was 0.44 for ke it was simple just subtract two kinetic energies! for pe find the rebound height of the ball and use mgh

what was the change in total energy?

 

[Hertz]

i wrote a stupid answer that it gives out more particles

i wrote "electron mass is not included in equation as it was very less mass :/ "

 

[Hertz]

what was Y? 1 or 2??

2

actually i wrote 1000 but ans is 500 for sure. we did one silly mistake. but the mistake is too complex to type so just accept it...n if u got 1000 like me, means ur node n antinode question was wrong :/ because from that only u get ur wavelength. u take diff between 2 anti nodes...into 2....then f=v/lamda u get 500 :/ total 4 marks gone as 1 mark for the formula

you must have forgot that in question it was mentioned 2.5/m/x10^6

i did not forget, u have forgotten on that question there was a 10^3 and some other stuff too

 

[WhereAmazingHappens]

no the answer of another guy is right

nope my answer is correct all of u have forgotten about the 10^3

I dont understand why people dont take example from you and admit their mistakes instead of arguing endlessly.

 

[AppleGreen]

nope my answer is correct all of u have forgotten about the 10^3

lol how come u can be so confident with a definitely wrong ans?

 

[WhereAmazingHappens]

So?i converted it into m for everyone if u want me to show u in cm i can

ah yes sorry i forgot that axes were labelled in cm sorry bro, got the same answer anyway

 

[JD REBORN]

ah yes sorry i forgot that axes were labelled in cm sorry bro, got the same answer anyway

its ok

I pray the GT is low.

Like very low.

Around 40.

guys , regarding question 1 , i forgot to change the unit of r from mm to m .. does that means i lose all the mark of the question , since the uncertainty of C are calculated from the value of C .. ? is it error carry forward or what ?

If u forgt 2 change r to m in the uncertainty part, its ok...u will still get d right ans....as error R/R so the 10^-3 will cancel out!!
