did you get T1 in shm as 0.429?

 

[anastasia grey113]

wasn't increased stability an advantage?

reduced gain was an advantage too

 

[anastasia grey113]

Is this correct. I wrote this line :
" The process in which a part of the output is fed into the inverting input and the input and the output are out of phase by 180 degrees "

And for the effects , I wrote :

a) Reduced gain
b) Lesser distortion

yh it should be

 

[anastasia grey113]

damn i didnt write 'part of the Vout' i just wrote Vout is fed
will i lose a mark?

Yess.. 0.43 s

 

[anastasia grey113]

did you get T1 in shm as 0.429?

yh
0.435 i think
i dont remember but it was something like that

 

[Tauqir_hamed]

WHAT DID YOU GUYS DO ? I DID T + (0.5 T ) .. THAT GAVE ME 0.43

 

[Zaki ali asghar]

(part of) the output is added to /returned to / mixed with the input

and is out of phase with the input / fed to inverting input
this is what the ms says. i think u'll get 2/2

 

[Zaki ali asghar]

the time period was for 8 boxes i think and we had to look at 12 .

OH THANK GOD

 

[anastasia grey113]

YH
had to multiply the time period with 1.5

hey y r computers required in CAT?
i wrote cuz they process and store such a large number of images so greater memory require and also display them

 

[Zaki ali asghar]

i wrote that computers processes the 2d images from slices to give a three dimensional image of the structure.

yh i wrote this two
exceeded the lines lol
but they mentioned 'why with a large memory' so i wrote abt that too

 

[Zaki ali asghar]

i think this is from W08

 

[Zaki ali asghar]

is photon a quantum/packet of energy of an electromagnetic wave right for 2 marks?

 

[haithsoul]

guys you should mention that part of the out put VOLTAGE is fed back not just output thats inaccurate

 

[Zaki ali asghar]

guys you should mention that part of the out put VOLTAGE is fed back not just output thats inaccurate

the mark scheme mentions output in brackets so i think it's fine without it too

 

[haithsoul]

the mark scheme mentions output in brackets so i think it's fine without it too

but always stresses on voltage, you must mention that it is the voltage that is fed back not just output

 

[Zaki ali asghar]

yeah voltage has to be mentioned.
