WHAT ARE THE VALUES OF MODULUS OF ELASTICITY & …

First of all, (kg/cm^2)*10^5 is not the correct unit for Young's modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9.

For ice-saturated basalt, Vs is always intermediate between that of ice and solid basalt, and Vs is always greater than 2.6 km/s (Fig-ure 1). Increasing porosity and pore oblateness both decrease velocity.
