physics paper 1,2 ........can we discuus da papper nw?

[Tharindu]

it wasn't p .. it was p/2 !! exactly which also decreases

Ok...lol it's common sense its not half....anyway my top post is the way I did it

 

[Tharindu]

it was A anyway according to my teacher whom i told the complete mcq when it was fresh in my memory

2/3P ??

leave it ;P !! on other threads i've got it confirmed that iwas p/2

p/2

Lol...ok whatever u think..what was your teacher answer for the bicycling one...question 3

what was urs ?

 

[Tharindu]

what was urs ?

Hmmm...I put A...but many are saying its B...wbu

the pressure thing was 2/3P, because there was a tap which separated the volume, so there was 100cm3 in the right side and 200cm3 in the left side, then when the tap is opened, the volume is distributed as 300cm3, so obviously pressure is inversely proportional and its should decrease.

YEAH EXACTLY DDDDDDD

bicycle thing was B, because the speed increases, when he goes down the hill, as the force of gravity pulls him down..so at the bottom f the first hill should be B

Yeah I kno..wanted to check..l

whose opening the tap btw LOl jus kiddin

agree it was B

 

[ashiqbal]

it was 2/3 P
see it was like this:
P1*V1=P2*V2
V1 WAS 200, V2 WAS 300
P1 WAS P
rearrange :
200P = 300P2
P2 = 200/300 P
P2= 2/3 P

Ok Wth man I can't remember the question exactly and type it...wrote it just to give you the idea...don't you have common sense...btw it's 2/3P I'm sure bro

2p/3 is the only answr it was surprising to know on other threads that people thought volume of gas was fixed i.e 200 cm3 instead that gas takes volume of container

 

[ashiqbal]

leave it ;P !! on other threads i've got it confirmed that iwas p/2

no you are wrong! see my explanation above!

 

[Tharindu]

a

agree it was B

Check how many people in this thread are giving the same explanation...

dude it was given i guess that the volume was fixed :/

nd how to keep the temperature of the wire constant in Paper 2 question 9?
how to safely dispose large amount of radioactive waste?
nd is the direction of conventional current the same in resistor as in the normal circuit?

safety dispose ans was B
