so......how was the paper?????

Active member

it was quite difficult for me
how much do u except

Active member

Yeah.......paper was a little bit more difficult nd lengthy than previous yr.........but still i did pretty well.......I xpet between 90-95

Active member

It wasn't as easy as Maths But was gud
A few Qs were a bit tough
Expect at least --------- 86
not less than that PlZZZZZZZZZ

Active member

I think it wasn't difficult .I missed 2marks by my mistake and expecting above 95.although my maths paper was worst i carelessly made mistakes i may get about 90 but my fault EX:i wrote in calculations32+16=38 and so on i think maths and science are coming to easy must not be like this .the paper must be tough and interesting as7-8years before.

Active member

yup..the paper wasn't difficult but it wasn't as wasy as maths...i lost 3 marks quite foolishly so i'm very upset...rest was gud..

Active member

it was easy....didnt expect it to be easy....yeah...the papers should be tough...atleast for next year batch!! Smile

but one question...

what did you guys write for this ques:

name the term which will not change for a machine of a given design-MA,VR or efficiency?

the energy changes in an electromagnet

Active member

VR
elctrical to magnetic or mechanical..

so anu..100 in phy??

Active member

can u plss show me the working of the thermal capacity ques in sec A??

Active member

johny...u sure with ur ans? me too wrote the same!!

hehe...started yur game of pulling my leg....i will be happy if i get that much, but i have also done one stupid silly mistake, which i had known well!....so, i hope to get more than 90....u? above 95?

Active member

so pullin legs yaar..i got that ques wrong ..n along with it that 42 degree one in sec A..i was soo silly..i drew the rite diag. n then cut it out n made the wrong one!!so above 95 is tuff..

Active member

actually, even i have a doubt....i am not sure.. coz for two marks, i did more working!!

first find the heat energy(h.e.) for 40g of water to cool to 30 from 60 degree. -1

then find the h.e. required to increase the temp of 50g....-2

subtract 2 from 1 to get h.e.-Q

the remaining heat is used for the vessel to get heated...

so, heat capacity= Q/t

t=30-20

hope its correct!!

Active member

wats the ans then??

Active member

actually i also did the same..but missd out in the working sumwere..

Active member

k...

i dont remem the ans...will work out now!

Active member

is it 294J/C?

Active member

hey dunn worry..u r rite...every1 got dis ans..dunno wer i went wrong...

Active member

i hope i did it correctly in the exam....i did this now and got this answer!! so, i dont remember what i have done in the papr!

you sure abt that VR thing?

n did u attempt that 10th radioactive ques? do u knw why the barium platinocyanide is coated on the glass screen? Suspect

i didnt attempt it...i am curious to know!

Active member

see, i told resistivity is not there...then that geiger thing...where is hari genius?

Active member

barium platinocyanide is coated for fluorescence.

Active member

whtz the heat capacity question

Active member

yaa..i did the 10th one...barium plat is a floursecent substance...so it produces flourescence..

Active member

ah...quest you there...so, are you studying in tenth ??? check out my ques and answer them ...plz Embarassed

the heat capacity of vessel...in q.4

Active member

my paper wsnt dat gud

Active member

i dnt hv the paper

Active member

and V R is correct
so is enrgy change frm electrical to magnetic
