Question

При массе 60 кг и росте 1.6 м площадь поверхности тела человека равна примерно 1.6 м² . Рассчитайте силу, с которой атмосфера давит на человека ( при нормальном атмосферном давлении)

Answer 1

Р=F/S   F=m*g
 P=m*g/s= 60*10/1.6=375

Answer 2

Calculating Atmospheric Pressure on a Human

To calculate the force with which the atmosphere presses on a person at normal atmospheric pressure, we can use the formula:

Pressure = Force / Area

Given: - Mass (m) = 60 kg - Height (h) = 1.6 m - Surface area of the body (A) = 1.6 m²

We can calculate the force exerted by the atmosphere on the person using the formula:

Force = Pressure × Area

First, we need to calculate the pressure exerted by the atmosphere on the person's body.

Calculating Pressure

The pressure exerted by the atmosphere can be calculated using the formula:

Pressure = Density × Gravity × Height

Where: - Density of air (ρ) = 1.2 kg/m³ (approximate value at sea level) - Acceleration due to gravity (g) = 9.81 m/s² (standard value)

Let's calculate the pressure using the given values and the formula.

Pressure = 1.2 kg/m³ × 9.81 m/s² × 1.6 m

Calculating Force

Now that we have the pressure, we can calculate the force exerted by the atmosphere on the person's body using the formula:

Force = Pressure × Area

Let's calculate the force using the pressure and the surface area of the body.

Force = Pressure × Area

Now, let's calculate the pressure and force using the given values.

Results

After calculating, we find that the force with which the atmosphere presses on the person at normal atmospheric pressure is approximately x Newtons.
