(b) as a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. calculate the pressure exerted on the floor by the heel if it has an area of 1.60 cm² and the woman’s mass is 55 kg. express the pressure in 106 pa (n/m2) for example, if the pressure is 68

P = 3.37 x 10 ⁶ Pa

Explanation:

Given that

A= 1.6 cm²

m = 55 kg

The weight W= m g

W= 55 x 9.81                       ( g= 9.81 m/s²)

W= 539.55 N

We know that force per unit area is known as pressure( P)

P = W/A

By putting the values

P= 539.55/1.6    N/cm²

P=337.21 N/cm²

P=337.21 x 10⁴ N/m²

P = 3.37 x 10 ⁶ Pa

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
