Please help me to solve this exercise step by step.

A strip foundation is installed in the two$-$layer base ground, as shown in Figure $1.$ The water table is located

at a depth $h_w$ from the ground surface, and the unit weight of water is ${}_w.$

Describe the ultimate bearing capacity of the foundation using the bearing capacity factors $N_c,N_{},$ and

$N_q,$ along with the parameters listed in Table $1.$

Select the parameters from Table required to obtain the bearing capacity factors $N_c,N_{},$ and $N_q$ from

Table $1.$
