Answer:
The total atmospheric pressure experienced by the person's whole body is, P = 202650 N/m²
Explanation:
Given data,
The surface area of the person, A = 2 m²
The standard atmospheric pressure is P = 101325 N/m² (or), Pascal
This is the amount of pressure experienced by 1 m² body at sea level.
If the surface area of the person is, A = 2 m², then the pressure becomes,
P = 2 x 101325 N/m²
= 202650 N/m²
Hence the total atmospheric pressure experienced by the person's whole body is, P = 202650 N/m²
Answer:
We have to show surface area [tex]=2m^2[/tex],with few conditions that is by considering Force [tex]=200000\ N[/tex] and Pressure [tex]=100000\ Pa[/tex] to be respectively.
Explanation:
The atmospheric pressure is [tex]=10^{5}\ Pa[/tex] on Earth's surface.
The magnitude of the force exerted on a person by the atmosphere is [tex]=2\times 10^{5}\N (or)\ 200kN\ (or)\ 20\ ton[/tex].
Now to calculate surface area we can find it from [tex]pressure=\frac{force}{area}[/tex] and re-arranging it to.
[tex]area=\frac{force}{pressure}[/tex]
So plugging the values,
Surface area [tex]=\frac{20000}{10000}=2\ m^{2}[/tex]
Hence from the above calculations we can say that surface area is [tex]2m^2[/tex].
So the surface area of an average person can be said to have [tex]2m^2[/tex], using the concept of pressure and force.
