Paper 6 Physics

[unplugged]

Yea , it is.
Anyhow , what about the circuit. Did you draw all 3 in a series alone or did you draw the parallel empty wire as well.

I kept that line empty and drew all lamps at the bottom.

+ the ammeter yea ?

Mine was

-------------- V -----------------

-----POWER SOURCE -------
| |

---- L ---- L ----- A ----------
V = Voltmeter
L = Lamp
A = Ammeter

 

[SexyFag]

Sorry, the forum screwed the above diagram

 

[unplugged]

Also , what did you mention the other reason for observing the filament heating up besides the resistance was?

 

[SexyFag]

I Said, If the Lamp was brighter, means it was more hot

I did it the same , i don't really know whether he wanted the empty line drawn. I got a hunch it doesn't matter but we'll see.

Exactly the same . Other answers could have been seeing if a duck would get cooked equally fast over the filament or something ;p.

Maybe, I Doubt It Do, however , they did say "rearranged" that means only the components were moved... but, im not sure

HAHAH Epic Answer =P

i think that the question says :what reading (readings of the student) that shows any heating effect so i said a change in current !! but i'm not happy with the exam bcz i've done silly faults :O:

I don't think the word reading was used. I recall it saying anything besides the resistance reading. But it didn't specify it had to be in the form of reading. And i think saying it glows more brightly provides a more elegant answer as it proves insight into the nature of the light bulbs.

Also saying the current did it is a bit cheeky as it's the same as saying the resistance. since they're directly correlated ;p. But who knows.

 

[Ramosk95]

then i'm ******** up !!!!!!!!!!!!!!!!!!!!!!!! :x

 

[Ramosk95]

guys i wrote in the last section of the first qsn :increse number of holes and draw more line is that true????

 

[unplugged]

Well , the question was asking how to prevent the paper from touching the bob as it reduces accuracy. So i don't think that's meaningful in that context. but again , that's just my interpretation of it.

 

[Ramosk95]

okay then it should be by using a mirror thats the right answer i think

ofcourse I added the ammeter.

Am not disagreeing with most of your answers.. However, the question stated that several students did the experiment with REASONABLE CARE. A question, that is almost similar to it, came in the past papers. In my own opinion, they are saying that the students did it ALMOST perfectly so any errors aren't probable. ANYONE AGREES ?

Well , parallex errors and not observing that something is vertical are common errors. Anyhow , what answers did you provide then?.

I mean perfect experiment would agree with theory , unless you wanna state theory is wrong which is a can of worms =_=.

I wrote the thickness of mirror and due to eye problem..

hmm , i didin't know thickness of mirrors effects their reflection. Are you thinking of lenses . And eye problems is unorthodox but seems fine , it's just another way of saying they didn't read it properly or position the things properly.
