Question

С какой F давление воздуха на ладонь s=50 (квадр.см) при давлении 760 мм рт столба?

Answer 1

50см2=0,005м2 760 мм рт ст=101308 Па
F=p*S=101308*0,005=506,54 Н

Answer 2

Calculating Air Pressure on the Palm

To calculate the air pressure on the palm (S=50 cm^2) at a pressure of 760 mmHg, we can use the formula:

Pressure = Force / Area

Where: - Pressure is the air pressure in mmHg - Force is the force exerted by the air on the palm - Area is the surface area of the palm

Calculation

Given: - Area (S) = 50 cm^2 - Pressure = 760 mmHg

We can use the formula to find the force exerted by the air on the palm:

Force = Pressure × Area

Substitute the given values: Force = 760 mmHg × 50 cm^2

Now, we can calculate the force:

Force = 760 mmHg × 50 cm^2 = 38,000 mmHg·cm^2

So, the force exerted by the air on the palm is 38,000 mmHg·cm^2 when the pressure is 760 mmHg.
