sum1 do it plz............

hey, that depends on the angle at which the rain is falling!!

On closing an open pipe, it was found that the third harmonic is higher by 100Hz with the frequency of open pipe, find the frequency of the open pipe?

read hc verma..........its given in detail...............

cumon guye, dont let me down................

thanx dude...............

how did u get dat????

wat is comedk?????

ne1 plz.............

sum1 reply.............

Draw the graph of the function-

y=[x] + |1-x|, -1<=x<=3

and determine the points, if any, where this function is not differentiable.

the electric field at a point associated with a light wave is

E=(100V/m)sin[(3 * 10^15)t] sin[(6 * 10^15)t].

If this light falls on a metal surface having a work function of 2eV, what will be the maximum kinetic energy of the photoelectrons?

yeah, dats a better method. however, d other will also do...........

i meant-

v=1/e[h*freq - work function]

thats d formula for stoppin potential............
