A certain pressure ' $P$ ' is applied to $1$ litre of water and $2$ litre of a liquid separately Water gets compressed to $0.01 \%$ whereas the liquid gets compressed to $0.03 \%$ The ratio of Bulk modulus of water to that of the liquid is $\frac{3}{x}$ The value of $x$ is ________
\[ B_{\text{water}} = \frac{-\Delta P}{\left(\frac{\Delta V}{V}\right)} \] \[ B_{\text{water}} = \frac{-\Delta P}{0.01} \times 100 \] \[ B_{\text{liquid}} = \frac{-\Delta P}{0.03} \times 100 \] \[ \frac{B_{\text{water}}}{B_{\text{liquid}}} = 3 \] \[ x = 1 \]
A wire of uniform resistance \(\lambda\) \(\Omega\)/m is bent into a circle of radius r and another piece of wire with length 2r is connected between points A and B (ACB) as shown in figure. The equivalent resistance between points A and B is_______ \(\Omega\).
The stress v/s strain graph of a material is as shown. Find the Young's modulus of the material. 

Mechanical properties of solids intricate the characteristics such as the resistance to deformation and their strength. Strength is the ability of an object to resist the applied stress, to what extent can it bear the stress.
