How'd your physics Papers go ?

[pakisatan123]

does any one remembers ques 1to7 of theory

 

[Fallen316]

Fallen316 Last thing I want to confirm is the answer to the question about latent heat...in which it was asked why the temp remains same...? is this explanation enough that the K.E of the particles is unchanged and the molecules are brought close....thus reducing their separation. Bonds are being formed.

yup. you're good

what was the ans to the moment mcq???

5N . A

 

[abdul arham]

HALA PHYSICS!!!!!!!!!!!! mine vent ausummmmm only one mark dropped!!!!!! yahpooooooo..
[ what was the answer of pressure/volume question in MCQ..?? ] it vas
2/3 P

 

[bravegirl123]

16.67 ohms

I also had this answer! yay \m/

what was the answer to the last two parts of the transformer wala question, btw? That power loss one.

Second last part: P=VI
Voltage was 240V, Current was 1.6A so 240x1.6 = 384W.
Last part: First we had to calculate the combined voltage dropped across the 2 lead resistors by V=IR that is 1.6x5 = 8V. Then using P=VI we could find how much power was lost overcoming the resistance of the lead resistors, since current remains same in series circuits, the power loss was 8x1.6 = 12.8W.
There were 2 other ways to calculate the power loss part, both will be accepted. It was a tricky question

 

[rajvansh]

of course not...

ohk thnx man, ppl at my place were sayin tht mrks would be detucted about tht!

 

[Minnie]

section B 1st question ki resistance....last part..

oh acha.

motorbike : A
centre of mass : C
radioactive : B
total amount : add up all values
unit : kWh

Are u sure the motorcycle one was A and cant the unit be Joule cuz its energy yaar!

Technically the energy unit is Joule but KWh is also used.. so maybe CIE can give us this margin of error

o bhai, mujhe maaf kar do, aap sahi ho.
mere se na pucho, please

 

[manicooljay]

wat was the answer for that convention current direction and electron direction..i wrote C

 

[Vogue]

wat was the answer to torque question????

 

[MustafaMotani]

wat was the answer to torque question????

wat was dat.. ?

 

[Vogue]

wat was dat.. ?

the one in MCQ. abt a pivot which had 2 forces down and 1 force up. nd v had to find magnitude of the force going up. the one which had option 5 N, 7 N , (dunt remember the 3rd one) and 17 N

 

[MustafaMotani]

5 N

 

[Vogue]

the same one in which the rod was in equilibrium. that was abt torque, no?

5N

 

[Vogue]

5 N

how 5 N. didnt the ans cum in negative

I think it was 10 N But not sure about it
