Physics P1 and P2: Discussi0n

[jafar]

he eve1, wassup hw was ur Physics paper, myne went really gud against my expectations, it was very exy

 

[saad]

yeah
but then again the ppr 2 was fairly complex

 

[jafar]

if u r havin ne prob, ask the question,
i nd odrs will be happy to answer

 

[sunshine]

what was the answer of million watt in P1.!!

 

[jafar]

500W,

 

[sunshine]

nooo.!
it was Q.2
that what is unit for million watt.!

 

[jafar]

tell me da question....

 

[sunshine]

paper 1
Q.2
that what is correct unit for million watt.!
A-MW

B-mW

C-Mw

D-mw

 

[Hashim]

it was C

 

[UxaiR]

hashim it was not C .! :mrgreen: :mrgreen: :mrgreen:
it's A

 

[hamid_ishfaq]

exactly it was MW that was C i guess in the paper here it is A!!!! yaar the paper was easy and it wnt well i jus made a silly mistake instead of using 1.5 as refractive index i used 150 God knows y bt i did i chkd d paper i guess more than 5 times corrected few mistakes but overlooked this one xcpt dat it wnt good and i was jus lyk on fire solvd d paper 1 in 20 min n paper 2 in 1 hour n dats it gt sum mistakes in paper 2 wich i corrected but only 1 in paper 1 and that was q 37 but i corrected it! I was jus wooooooowwwww man

here a link for you to confirm .!! :mrgreen: :mrgreen: :mrgreen: :mrgreen:

 

[farrukh]

the answer was MW to the question 2.

Can anybody tell me the answer to the mcq that asked for principal energy conversion of a parachutist falling at constant speed???
Also what was the experiment to investigate effect of temperature on resistance?

 

[UxaiR]

Q.principal energy conversion of a parachutist falling at constant speed???
A.gravitational potential energy ------------> kinetic energy .!

Q.experiment to investigate effect of temperature on resistance?
A.make a circuit diagram add ammeter and voltmeter in it .!!
ammeter in series and volt parallel to that place where you where heating the wire .!!
then measure the current and potential difference in different temp and record them in a table than calculate the resistance by V=IR

 

[Azra]

i liked that paper,, it was awesome!!!!

the energy one was potential to heat coz the speed was constant

 

[habib123]

man what was the answer of the waves question the number of waves i think in one second what was its answer

it was gravitational 2 heat cox the speed ws cnstnt so the potential was nt bein cnvrtd 2 kinetic

 

[Jezla]

No, it has to be potential energy to kinetic energy 'coz the parachutist was MOVING!!

 

[af1992]

yeah it was moving bt wasnt gaining kinetic energy whereas on the odr hand it was losing potential energy so thr had 2 b sum cnversion odr than the kinetic...kinetis ix half mv square...the mass n speed wer cnstnt so thr wasnt any chnge in kinetic
