8.
Pressure = Force / Area
= 300 N / (30 × 10^-4 m^2)
= 10^5 Pa
9.
Force = Pressure × Area
= 20 × 10^3 × (10^-4)
= 2 N
10.
Pressure = Force / Area
= 60 N / (15 × 20 × 10^-4 m^2)
= 2000 Pa
11.
Pressure = Force / Area
= 100 kgf / 0.5 m^2
= 200 kgf / m^2
12.
Pressure = Force / Area
= (60 × 10 N) / (2.5 × 0.5 × 10^-4 m^2)
= 4.8 × 10^6 Pa
