Question

При массе 60 кг и росте 1,6 м площадь поверхности тела человека равна 1,6 квадратных метров. Рассчитайте силу, с которой атмосфера давит на человека(при нормальном атмосферном давлении).

Answer 1

P=F/S
F=ps=10(5)Па*1.65м2=165000 Н=165кН

Answer 2

Calculation of the Force Exerted by the Atmosphere on a Person

To calculate the force exerted by the atmosphere on a person, we can use the formula:

Force = Pressure x Area

In this case, the pressure is the atmospheric pressure and the area is the surface area of the person's body.

Given: - Mass of the person: 60 kg - Height of the person: 1.6 m - Surface area of the person's body: 1.6 square meters

We need to determine the atmospheric pressure to calculate the force.

According to the search results, the normal atmospheric pressure is approximately 101,325 pascals or 1013.25 millibars (mb)

Using this information, we can calculate the force exerted by the atmosphere on the person.

Step 1: Convert the atmospheric pressure from millibars to pascals. - 1 millibar (mb) = 100 pascals (Pa)

Therefore, the atmospheric pressure is: 1013.25 mb x 100 Pa/mb = 101,325 Pa

Step 2: Calculate the force exerted by the atmosphere. - Pressure = 101,325 Pa - Area = 1.6 square meters

Using the formula Force = Pressure x Area, we can calculate the force:

Force = 101,325 Pa x 1.6 m² = 162,120 N

Therefore, the force exerted by the atmosphere on the person is approximately 162,120 Newtons.

Please note that this calculation assumes that the person is standing upright and that the force is evenly distributed over the entire surface area of the body.
