what r d products ven CaNCN is hydrolysed?
i op agrawal it gives urea while in op tandon its ammonia.
which 1 is rite?
there is no mention of conditions i.e.temperature,pressure or concentration in ne of d books.
pls help.

|
concentration of what?
if NaCl then d above ans is rite.
if Bromine den 0.
|
|
|
|
e^2nh.
apply conservation of energy.
then apply concept of coefficient of restitution n number of times to get the ans.

but as rg 123 pointed out i m not getting f(x)=2x + c as a solution of the given functional equation.
may b experts will help.

joy im not gettin f'(x) = 0.
i m gettin f'(x) = lim {y tends to 0} [f(3y) - f(0)]/2y.
which independent of x and hence constant(=2,as f'(0) = 2).
hence f'(5)= 2.
good question.

this book is d bibble.i worship it.
dont read this book if u want to clear iit jee.
read this book if u r a teacher or u want to crack jee.

consider earth + ball system.hence momentum is conserved.
|
|
|
|
are u sure the function is not
{( 3x+4x)/2}2/x

i mean if it moves innitially with const. linear velocity.(no angular velocity).

friction acts to the left.

dear biki,
study SHM(work power energy wud also do) to clear dis doubt.
d body wud hav some KE(=work done by spring force) at x = mg/k.vich wud take it to x=2*mg/k.

dear prakhar,
consider forces acting on d body(newtons 2 law).
