how was physics paper 12? (no discussions till 24 hours)

[Zaheen]

Wat did u guys give on q38

 

[chandradas]

Q2 ? Abt the force component... w=tsin¤ or w=tcos¤ ?
Q8 ? The space craft question? I chose C) 0.8 mg ...?
Q) the question abt water moving through turbine under surface? I guessed it C) 1.7 Mega smth
Q) the graph about variation of voltage when potemtiometer moves from x to y? Its constsnt..straght horizontal line right?
Q) the one where we have 2 and 4 resistance resistors and we need to choose the graph for the voltage across from x to y...it was A?
Q39) how to increasr angle of deflection of alpha particles?? C ? Use double foil?
Q38) the total emf? I guessed bit 4V B... I think its 6V?
QX) the one about whats the angle for diffraction ? Sin^-1 x (wavelength/D) right?
Gimme more questions ?

Q8 mg because gravitational force never changes in a planet.
Q38 it is 6V
and QX.. and of diffraction is twice of your answer.. thats what i think.

 

[Irahman]

what was the answer for uncertinity?

 

[moinul]

why is 6v of 36 number . can anyone explain? my 1 was different..

 

[Zaheen]

What did u guys give for the powerstation

 

[Avik181]

I have figure out that 8 questions were.repeated but as we cant discuss now i will post all the repaeted questions at 2pm !!!!

dude where are the 8 repeat questions?! i just got 2

What did u guys give for the powerstation

What did u guys give for the powerstation

90MJ

 

[DumbIdiot]

for num 39( or 38) , the question about the graph
wasnt the answer D ( potential is zero at Y)

what about the question about the bow .
was the answer 53?

did any of you guys get 1.5MJ as answer for one of the questions

average speed of aeroplane = 480

and finally the question about the lamps.
did both lamps have normal brightness?

 

[Irahman]

I need.Please inbox me.

U need what?

 

[Zaheen]

Which were repeat questions ???

 

[Irahman]

o

U asked who needs questions.
So i said yes..

ohh sry I meant I need some questions.....

we all should check it and discuss. so it would be better to discus it here...
as time is going on i m forgetting my answers...

about the wave question..it was stationary n transverse right?
another question about avarage speed. i found it 480m/s...

 

[pkLuffy]

Hey does anyone remember what were the repeated questions and from which year dey were?...I wanted to rechek..Um so unsure about my xam ((

Was the answer of the bow question 53? is nyone 100% sure??

 

[Irahman]

yes

about the wave question..it was stationary n transverse right?
another question about avarage speed. i found it 480m/s...

it will be transverse nd stationary all r correct.........pls do ask more....

 

[Irahman]
