Question

на какую высоту надо подняться чтобы атмосферное давление уменьшилось на 1мм. ртутного столба?

Answer 1

В среднем оно уменьшается на 1 мм.рт.ст каждые 12 метров

Answer 2

При небольших изменениях высоты в среднем на каждые 12 м подъема давление уменьшается на 1 мм рт. ст.

Answer 3

Calculating the Height for Atmospheric Pressure Change

To calculate the height at which the atmospheric pressure decreases by 1 mm of mercury, we can use the formula:

h = 2cosθ/gR

Where: - h = height - θ = angle from the vertical to the line of sight - g = acceleration due to gravity - R = gas constant

Using this formula, we can calculate the height required for a 1 mm Hg pressure change.

The formula indicates that the height is inversely proportional to the cosine of the angle and directly proportional to the gas constant.

Conclusion

Based on the provided formula, the height required for the atmospheric pressure to decrease by 1 mm of mercury can be calculated using the given parameters.
