Answer: a) P = 13,32 N /cm²

Step-by-step explanation:

Pressure = Normal Force : Area

P = F : A

Normal force = Weight = mg

g = gravitational acceleration = 9,8 m/s² = 9,8 N/kg

P = mg / A = 34 kg x 9,8 N/kg : 25 cm² = 13,32 N/cm²

Answer:

13.3 N/cm²

Step-by-step explanation:

Given:

A = 25.0 cm²

m = 34.0 kg

g = 9.80 m/s²


\boxed{P=(F)/(A)}


P=(w)/(A)


P=(mg)/(A)


=(34*9.8)/(25)


=13.3\ N/cm^2
