both of u have not got the correct answer....neva mind...maybe calculation...just tell the method...

Find R AB, R AN .... (each side represents the value of resistance)

(if the pic. isnt clear..then take r1,r2 ....n give the method.... )

(the values are 6,2,10,3,15,4) clockwise....

which is better material science and metallurgy at any IIT or electrical/mechanical at IT-BHU?

a line bisecting the ordinate PN of a point P(at^2,2at), t>0,on the parabola y^2=4ax is drawn parallel to the axis to meet the curve at Q.if NQ meets the tangent at the vertex at the point T,then what are the co-ordinates of T?

solve $\int_{0}^{\infty} log (x + 1/x) dx / (1+{x}^{2})$

cummon guys i want more suggestions..

hey guys i m in big confusion,,my jee score comes out to b somewhere in between 220-230 and the rank that is expected is in 2000s...so the only option left is either take materials and metalurgical engg. or civil...so cud u tell me wat wud b the future prospects in both these branches???

i think that this function is non integrable.........

a spherical shell of inner and oter radii r and R has thermal conductivity k=rho/x,where k is a constant and x is the distance from the centre of the shell. if inner and outer walls are maintained at diff. constant temp. T1 and T2 then what is x for isothermal surface of temp. T1 + T2 / 2 ?

an electron in hydrogenn like atom is in excited state. it has total energy of -3.4eV.then

a. KE of the electron is 3.4eV
b. KE of the electron is 6.6eV
c. De Broglie wavelength is 6.6angstrom
d. PE of the electron is -6.8eV

for the reaction q value is -ve,(if m1 is the mass of projectile, m2 is the mass of the target nucleus) then wat is the threshold energy to initiate the reaction?

ans: -q(m1/m2 +1)

pls tell me the method of solving T/t=4....thats wat i m not getting,,,

please explain me in detail...

a massless rod AB of length L is hung from two identical wires of equal length.A block of mass 'm' is attached at point O on the rod. find the value of AO so that a tuning fork excites the wire on the left in its fundamental tone and the wire on the right in its second harmonic.

ans. L/5
