Physics P1 and P2: Discussi0n

@ Mobeen: because the inverse graphs have exponential curves.

.........in section B 2nd last question, my answer for no. of pulses was 166666... something.. but each pulse produced 2 complete waves in case anyone noticed...was the ques. about no. of pulses or no. of waves??????????

........i drew the compass needles this way:
N<-----(s)----->N
this was because i thought the needles are north-seeking and point towards north, don't they???

 

[beststriker]

yes u r rite, yr tension hi hoti hai agr kuch gult ho jaye......is liye ab sirf achey grade k liye dua kro..

no, u draw them wrong. it was the North pole of compass which was attracted towards the south pole of magnet.
you draw the arrows in the wrong direction with wrong north poles.....

Gyx plz ans da folowng:
Paper1:

* wat was da charges nd size og magnitude of chrges on the two metal spheres P nd Q which wer being rubed
*was da ans to da d.c. motor ques. dat current in coil reverses after coil passes its vertical position

Paper 2:
* wat was da ans to ques. 1 last part which asked dat why resultnt force vil be zero if distance is 700m...
* wat was da shape of da current nd p.d. graph in section B last ques......

TENSED........ PLZ HELP>>>>>>

 

[jafar]

@Talha ;
*equal charges
*yes veritcal

*b/c it wud go 350N and then 350S so overall displacement wud be zero
* what do u mean shape ov da current??

 

[jafar]

current against Voltage

 

[habib123]

trhe grap of the pressure area question was a straight line because the force was constant i chose d but my friend told me it was c and then i corrected it

 

[beststriker]

what do u think guyz will be the minimum marks to score an A* in physics.

 

[Abdullahkhan92]

Total marks in all papers..... i think 121/145 wud be enuf for an A* i think.......

 

[mehdi1028]

131/145 === A*
117/145 === A

 

[mehdi1028]

WHAT IS Braking Distance and Thinking DisTancE?????????

 

[allthatglitters16]

braking distance: Braking distance refers to the distance a vehicle will travel from the point where its brakes are fully applied to when it comes to a complete stop

Thinking Distance:the distance covered in the time the driver takes to react to a certain change.
Hope it helps

 

[allthatglitters16]

please tell me what was the efficiency calculated in question 2 last part section A paper 2

 

[OakMoon!]

74.8%

 

[Abdullahkhan92]

131/145 === A*
117/145 === A

that is in percentage..... the calculations CIE does are in percentile... which is always lower than the actual percentage.....

 

[OakMoon!]

trhe grap of the pressure area question was a straight line because the force was constant i chose d but my friend told me it was c and then i corrected it

it was D... INVERSELY PROPORTIONAL ka matlab hi yehi hai keh when the two values are multiplied they give a constant value and inv proportional ka graph is a curve... suppose the mass is 1 kg... its weight is 10 N divide it by area
10/1=10
10/2=5
10/3=3.33
10/4=2.5
it will make a curve.... chek kar lo...

 

[haris_93]

what about the fuse question??? was it A ....excess charge would be earthed and the fuse would not blow or B ...the fuse would blow????
i chose A.....

 

[Ali23]

da answer 4 fuse question is tht when da fuse blows the connection break out n ur device became safe!!!!!!it is B

 

[allthatglitters16]

@hamidali391
thanks so much.
i got the same.. but my friend confused me when she said its 95.4%

 

[KingovHeartz]

Can any 1 clear my doubts abt sme listed mcqs?

What was the ans of the mcq regarding Manometer?

What was the ans of MCq Regarding fuse? I think fuse will not melt.. M i right?


wHAT`S THE ANS OF MCQ WHICH WAS ABT FUSION n fiSion?

Lastly, tell me the ans of mcq regarding thunder andlightning..
