Question

A woman is wearing high heels. If she stands on the on one heels, she puts a pressure of 1200N/cm 2 on the ground and each heel has a surface area of 0.5cm 2 what is her weight in newtons?

Answer 1

Answer:

down

Explanation:

You must know that Pressure= Force/ Area

So we have ,

Force= 500N

Area=1 Square cm = 10^-4 Square meter.

**In question the area must be 1 Square cm .

So we get Pressure=

5*10^6 Newton/Square meter = 5*10^6 Pascal.

UNITS

Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per Squaremeter; similarly, the pound-force per squareinch (psi) is the traditional unit of pressure .
