Question

Турист, поднявшись на холм, заметил, что показания барометра-анероида уменьшились на 5 мм рт. ст.Чему равна высота холма?ответ будет ( 60 м) но мне нужно решение

Answer 1

1 мм.рт.ст.=12

 12*5=60 

Answer 2

Calculating the Height of the Hill

To calculate the height of the hill, we can use the formula for the relationship between the change in atmospheric pressure and the change in altitude. The formula is:

Δh = -ΔP / (ρ * g)

Where: - Δh = change in altitude - ΔP = change in pressure - ρ = density of air - g = acceleration due to gravity

Given Information

The tourist noticed a decrease in the barometric pressure by 5 mm Hg (which is equivalent to 5 mm Hg / 13.6 = 0.367 atm) as he ascended the hill.

Density of Air

The density of air at sea level is approximately 1.225 kg/m^3.

Acceleration Due to Gravity

The standard value for acceleration due to gravity is approximately 9.81 m/s^2.

Calculation

Plugging in the given values into the formula: Δh = -ΔP / (ρ * g) Δh = -(0.367 atm) / (1.225 kg/m^3 * 9.81 m/s^2) Δh ≈ -0.030 m

The negative sign indicates that the tourist ascended the hill. Therefore, the height of the hill is approximately 30 meters.

So, the height of the hill is approximately 30 meters.
