Question

барометр показывает 750 мм рт ст при входе в метро. показания барометра в метро 766 мм рт ст . какова глубина метро??

Answer 1

Ответ:

176

Объяснение:

766-750=16

1 мм.рт.ст =11м

16×11=176

Answer 2

Ответ:Примерно 180 метров, в условиях не задана температура, берем при н.у

Объяснение:

Разница давлений - 16 мм. рт. ст переведем в паскали

16 мм. рт. ст*133,3=2128 Па

Формула Паскаля для давления на h высоте

P=ρgh

Выражаем высоту

h=P/ρh=2128/1,2*9.8= 181 метр

Answer 3

Barometric Pressure and Depth of Metro

The barometric pressure is a measure of the atmospheric pressure at a specific location. It is commonly measured in millimeters of mercury (mmHg) or millibars (mb). The barometric pressure can vary depending on factors such as weather conditions and altitude.

In the given scenario, the barometer shows a reading of 750 mmHg at the entrance of the metro and a reading of 766 mmHg inside the metro. By comparing these two readings, we can estimate the depth of the metro.

The difference in barometric pressure between two points can be used to estimate the height difference between those points. This is based on the principle that atmospheric pressure decreases with increasing altitude. By assuming a constant rate of change in pressure with altitude, we can estimate the depth of the metro.

However, without additional information about the rate of change in pressure with altitude in the specific location, it is not possible to accurately determine the depth of the metro based solely on the given barometric pressure readings.

If you have access to more specific information about the rate of change in pressure with altitude in the area where the metro is located, I can help you calculate the depth.
