Answer:
Step-by-step explanation:
in all the question we have to use same technique
in 1 question
weight/force exerted by dorje(F)=1500N
total surface area of sole(A)=0.5m²
we know that,
P=
![(F)/(A)](https://img.qammunity.org/2021/formulas/physics/college/vb14uihydmkezo9bld81mruf3zfhe0tjdm.png)
or, p=
![(1500)/(0.5)](https://img.qammunity.org/2021/formulas/biology/high-school/exatwollwhybemt8j199z0vjxviwqsgdd7.png)
∴ P=3000pa
in question 2nd
pressure(P)=40 pa
force exerted by block(F)=80N
we know,
pressure(P)=
![(Force(F))/(Area(a))](https://img.qammunity.org/2021/formulas/biology/high-school/y3voc9sna4kbzcbrl1tre7mps1zmgh7j6i.png)
area=
![(80)/(40)](https://img.qammunity.org/2021/formulas/mathematics/high-school/9cud01jqt3pxhanhqeeyx3biszpwig5w7s.png)
∴area =2m
ow you can do other by yourself
