Question

A man has a mass of 75 kg; his shoes have a surface area of 92 cm², and therefore, the pressure
exerted because of his weight is:
A. 25 x 10³ N/m²
B. 2.5 X 10⁵ N/m²
C. 7.5 x 10⁴ N/m²
D. 7.5 x 10² N/m²​

Answer 1

Explanation:

Pascal = 1 Newton / Meter^2

Pressure = Force / Area

500 Pa = 5 N / A

100 1/m^2 = 1/A

A = 1/100 m^2

you can leave that as your answer, or you can convert:

100 cm / m

10000 cm^2/m^2

A = 1/100 m^2 * 10000 cm^2 / m^2

A = 100 cm^2

Hope this helps
