Physics: Post your doubts here!

ye

well it was friction between the tyres and floor so it decreased since mechanical energy was being converted to heat
wut did u write?

yes, the question also mentioned that the springs were always extended, so their was friction amongs their molecules right?

lol idk i dint write in those terms
i just wrote abt friction i thought that as the trolley's tyres rubbed against the floor, friction was there.

yeah i mentioned that as well. For the question about communication for 1 mark where it asked about time from max to min modulation what was the answer?

How was 9702_42 everyone? Quite good for me!!

I messed up it was really different this time dont know what I'll get.

 

[amina1300]

w

hat did you get here? for final T

Couldn't get to that part time ran out

 

[amina1300]

you had to draw them in paraller or series.
4 was if i remember two parallel and one series
9 was two series and then those two are in parallel with the other one.

What value did you get for combined capacitance

 

[anastasia grey113]

What value did you get for combined capacitance

1.2 i think

 

[haithsoul]

Couldn't get to that part time ran out

what about the ampilfier last questions on how to connect a component while the gain is stable?

 

[haithsoul]

1.2 i think

i put 2.4 since its min to max, are you sure its 1.2

 

[amina1300]

What do you guys think the threshold will be this time?

 

[Holmes]

1.2 i think

Yes that's what I wrote but my friends say it was sth like 2.4 or what idk

 

[anastasia grey113]

i put 2.4 since its min to max, are you sure its 1.2

yh m talking abt the capacitance
v just had to do 1/C = 1/2 + 1/3

 

[anastasia grey113]

What do you guys think the threshold will be this time?

well the paper was kind of different and tricky
but still it was easy
it should be in the high 50s i suppose

 

[anastasia grey113]

Yes that's what I wrote but my friends say it was sth like 2.4 or what idk

2.4 how?
i discussed it with my friends
they all had 1.2

 

[amina1300]

How were we supposed to draw the deflection path of the particle

 

[anastasia grey113]

How were we supposed to draw the deflection path of the particle

with a greater radius
just a liiiiiiiiiil greater

 

[haithsoul]

yh m talking abt the capacitance

yeah

 

[amina1300]

2.4 how?
i discussed it with my friends
they all had 1.2

I had 1.2 too so idk

 

[anastasia grey113]

yeah

yh so thaz 1.2

 

[haithsoul]

with a greater radius
just a liiiiiiiiiil greater

yeap although my dumb hand was shaking couldnt draw a proper curve
