hi buddy!! m frm jal..
c DAVIET being a pvt institute is damn strict towards studies...one has to really work hard if u wanna b a decent student (u knw m saying dis bcoz dere s not dat much strictness in govt collgs).....
k..lemme tell u its only 4-5 years old institute...but has managed to get a decent repo...ece being most preferred subject is a gud option..last year an ece student got highest packg 4.5 lakh n also had a call frm SYMBIOSIS ,PUNE fer mba...so itz a decent institute...dat it has managed to get in top 3 collgs uf PUNJAB CET in such a few years..
so itz a gud option after gndu under pb.cet..

buddy may b due to temp effect on material's prperties i thinnk.....
correct me if m wrong....
|
|

yep buddy..its PURELY an electromagnetic force.........
electromagnetic forces b/w electrons n protons of string near lower n upper end produce resultant force preventing a directly attached body (like a block) to fall.....n this is tension....
u shud read:
hcv1 pg no.58 (the forces) right side para 2 frm above
rate me if found useful....

hey buddy...!!in dis phenomenan always half of the energy is dissipiated as heat n half is stored as elastic pot energy.....
|
|
|
|
is it:
the whole integral of { [f(b)-f(a)]/(b-a)dx}
|
|
|
|
f(x)=tan(inverse)x; x lies b/w -1 n 1(including both)
=(1-x)/2;x less than -1
=(x-1)/2;x greater than 1
so deriv of f(x)=1/(1+x square)
=-1/2
=1/2 limits as same above
but its discont at -1 n 1
so domain is r-{-1,1}
rate me if m right.....

dude u can go fer these:
phy:hcv n halliday is enuff...irodov is damn tuff from point uf view of mathemetical application in physics
chem: numerical chem:p bahadur
org:arihant/morrison boyd
inorganic:me thinx NCERT or other simpler text buks r enuff (as it is cramming oriented)
maths:a das gupta,k c sinha, purshottam kumar sharma(r suitable for jee prepn)
