As a stands, her entire weight is momentarily placed on the heels of her high-heeled shoes. Calculate the pressure exerted on th

Lena [83]

Answer:

Pressure will be $6072449.952Pa$

Explanation:

We have given mass of the women m = 65 kg

Radius of the heels r = 0.578 cm = 0.00578 m

We have to find the pressure

We know that pressure is given by

$P=\frac{F}{A}=\frac{mg}{A}$

So force F = mg = 65×9.8 = 637 N

Area $A=\pi r^2=3.14\times 0.00578^2=1.049\times 10^{-4}m^2$

So pressure $p=\frac{637}{1.049\times 10^{-4}}=6072449.952Pa$

A container is filled to a depth of 19.0 cm with water. On top of the water floats a 31.0-cm-thick layer of oil with specific gr

IceJOKER [234]

Answer:

Absolute pressure of the oil will be 102822.8 Pa

Explanation:

We have given height h = 31 cm = 0.31 m

Acceleration due to gravity $g=9.8m/sec^2$

Specific gravity of oil = 0.600

So density of oil $\rho =0.6\times 1000=600kg/m^3$

We know that absolute pressure is given by $P=P_0+\rho gh$ , here $P_0=1.01\times 10^5Pa$

So absolute pressure will be equal to $P=1.01\times 10^5+600\times 9.8\times 0.31=102822.8Pa$

So absolute pressure of the oil will be 102822.8 Pa
