Equivalent conductance `(^^)` vs concentration graphs are given for some electrolytes X,Y and Z. Here X,Y and Z are

The variation of equivalent conductance versus concentration of a strong electrolyte is correctly given in the plot

X,Y and Z in the above graph are

The figure shows three concentric , conducting ,spherical shells X,Y and Z with radii r, 2r and 3r respectively . X and Z are connected by a conducting wire and Y is uniformly charged to charge Q . Find: (a) charges on shells X and Z , (b) potentials of X and Y .

The volume vs. temperature graph of 1 mole of an ideal gas is given below The pressure of the gas (in atm) at X, Y and Z, respectively, are

An unstable nucleus X can decay into two stable nuclie Y and Z A sample containing only X is taken at t=0 Three graphs log_(e)(N_(x) vs t, N_(x), vs t and N_(z) vs t are drawn as shown below Here N_(x),N_(y) and N_(z) represent number of nuclei of X,Y and Z repectively at any instant. t Choose the correct choice (s) from the following :

Observe the above graph and identify x, y, z.

What is the proportion equivalent to X/Y : Y/Z : X/Z," if "X : Y : Z = 4 : 7 : 9 ?
