for the power one i wrote 5 sec one cus less time greatest poswer
n the barometer it was B so obvious
n the eco i wrote the walla which was on the right side
cuz it was the shortest distance:)
am i vorrect?

Yea, I wrote the same answers!

[MaNa]

but i screwed up 2 question which i was so pissed off
i knew the ans..but i over rules my insticnt!!!
the longitudnal one...
i said 14n2
but i KNEW the ans was 2n4
bte the pressure for pistion
 both ould dec right
Pressure 100% dec what about density

Few of my friends also thought 1, i was sure that it was 2 and 4 though.
Yup, pressure and density both decrease. It is mainly due to the increase in volume.

it is 2 n 4
cuz waves in water r transversal
n thee shallow to deep was D right?

The shallow one, I got C. Because when it goes into the shallow area, it moves slower, thus wavelength decreases, and since it has entered the area at an angle, it will refract (towards the normal in this case). D, although showed a decrease in wavelength, but the there was no refraction..so i think C is wrong..Sorry about that
Well, good luck for chemistry, if you take chemistry

[MaNa]

yaa i do take chesm:)
good luck to u too
anyways i hope i got it correct:)

[MR.BooMBastiC]

yeah it was c
the rays in d were not bending even tho their wavelength changed!!

Oo baga!!! i got some qs wrong

[girl_92]

i got C for tht as well

no problemlemo.....

we can compromise upto 9-10 marks!!!

hmm ,..
how was ur exam
did u got any wrong??

[Christy]

i dont remember wat i wrote

wat was the answer for the wire into the page and the compasses ??

[sweetest angel]

Meee ..

For the barometer tube , First i chose B .. then rubbed it and chose C : (this question is repeatd 'n answer is C
For the echo , i chosed XW(im not sure about the letters) .. but its the shortest wall under the source of sound also repeated answer is da wall at the end..i guess its called smeting and Z
For the Fuse .. The circiut breaker in the live wire ( at X ) .. and the fuse at y ..always in live thus XX
For the cooper .. me too .. i chosed the other end of the woodrepeated 'n yes!

indeed , it was tricky
