For a homogeneous isotropic material, which one of the following cannot be the value of Poisson’s ratio?

$A$ wire of length $L$ and radius $r$ is loaded with a weight $Mg$. If $Y$ and $\sigma$ denote the Young's modulus and Poisson's ratio of the material of the wire respectively,then the decrease in the radius of the wire $(\Delta r)$ is given by:

Give the relation between shear modulus $(G)$ and Young's modulus $(Y)$ for an isotropic material.

The value of Poisson's ratio lies between

If there is no change in the volume of a wire upon stretching,then the Poisson's ratio for the material of the wire is:

For silver,Young's modulus is $7.25 \times 10^{10} \ N/m^2$ and Bulk modulus is $11 \times 10^{10} \ N/m^2$. Its Poisson's ratio will be
