for reflexive  aRa or bRb should be there

and for transitive the condition should be aRc , bRc then aRb

if the points (0,0),(1,0),(0,1)and (t,t) r concyclic then t =

a.-1      b.1      c.2        d.-2

is equal to

1.f(x)/g'(x)      2.f'(x)g(x) - f(x)g'(x)

3.f(x)g'(x) -. f'(x)g(x)            4.f'(x)g(x) + f(x)g'(x)

pls do this goiitians !rating assured

as we know,

w/e=q/f  i.e. gram equivalent is equal to the no of faraday  ( from faraday 1,2 law)

w=weight , e=equivalent weight  q=charge,    f= faraday

using this formula we can find the equivqlent weight , 0.66/e=2*100/96500 , e=318.5

now we know that electrochemical equivalent (z) is given by  e/f=318.5/96500=.0033

z=3.3*10-3

work done is f.ds...............(1)

force is i+j+k

and the work is done from pt a (3,3,3) to b (4,4,4)

from 1, ds represent the change in displacemant ,therefore ds=(4-3)i+(4-3)j+(4-3)k =i+j+k

again from 1,  w=f.ds

(i+j+k)(i+j+k)=1+1+1=3
