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

[Mayedah]

velocitry increasing acceleration decreasing..

Explanation

 

[17194]

One thing i know, I had NONE wrong. (though i dont remember a few questions, but if you tell me the info. in the question then definitely i can tell you the answer)
And i don't remember the fuse question, so mind telling me the values? but yeah i remember something like 25 A but idk whether it was my calculated value or one of the options..

For the fuse question the calculated current was 25A and the correct option was a 30A fuse. I think that option was either B or C.

 

[MustafaMotani]

plus for the metal conductor which option was right ??

through vibrations and electrons

 

[MustafaMotani]

Explanation

when upward force increase accleration decreases and as there is some acceleration velocity increases

 

[17194]

Explanation

As an object falls its velocity increases, and due to wind resistance the initial acceleration of 10m s-2 decreases.

 

[MustafaMotani]

have found some of my answers wrong,hell worried

Never discuss then..

For the fuse question the calculated current was 25A and the correct option was a 30A fuse. I think that option was either B or C.

Remember the values in the question like what was the power /voltage?

30 A is ryt

 

[asd]

30 A is ryt

THE POWER RATING DUH! . ^^
I know it was 30 A.

 

[MustafaMotani]

lets ask others about this. cuz im not quite sure myself
guys, are these 2 resistors connected in series or parallel ??
View attachment 10887

series...
yeah in paper they were in series power loss was (1.6)^2 x 5 = 12.8

 

[MustafaMotani]

yes , it was

they are cheap as well as light.

loss of energy in optic fibres is less isnt it .. ??

 

[MustafaMotani]

wait. were we supposed to write the poles in the ring as well ?
i just drew lines from primary coil to secondary coil .

I did mention it... its better to do extra ..

 

[MustafaMotani]

Can anyone tell me wats percentile.. ??

 

[Fallen316]

Can anyone tell me wats percentile.. ??

Google

 

[MustafaMotani]

Is it so hard for anyone to explain ....

 

[plantaholic]

13n i am sure,wat was anser of magnetic field line ques sec b

mine was 13 N too

 

[plantaholic]

hey how did u get 13 N for the moment

it was the balanced see saw one. right? i remeber doing upwards = downwards forces

 

[MustafaMotani]

for example I get distinction Then will I be notified.. ??

 

[pakisatan123]

xar frequency walay ka 2 multiply 60 tha na

 

[MustafaMotani]

it was the balanced see saw one. right? i remeber doing upwards = downwards forces

thats the wrng concept.. it isnt upward force=downward force... It is anticlokwise moments= clockwise moments
