Let $$\psi $$ represent soil suction head and K represent hydraulic conductivity of the soil. If the soil moisture content $$\theta$$ increases, which one of the following statements is TRUE?

An uncompacted heap of soil has a volume of 10000 m³ and void ratio of 1. If the soil is compacted to a volume of 7500 m³, then the corresponding void ratio of the compacted soil is __________. (round off to one decimal place)

A concentrated vertical load of 3000 kN is applied on a horizontal ground surface. Points P and Q are at depths 1 m and 2 m below the ground, respectively, along the line of application of the load. Considering the ground to be a linearly elastic, isotropic, semi-infinite medium, the ratio of the increase in vertical stress at P to the increase in vertical stress at Q is ___________. (in integer)

At a site, Static Cone Penetration Test was carried out. The measured point (tip) resistance q_c was 1000 kPa at a certain depth. The friction ratio (f_r) was estimated as 1% at the same depth.

The value of sleeve (side) friction (in kPa) at that depth was __________. (in integer)
