Question

Определите давление атмосферного воздуха , если он давит с силой 1,2 Кн на оконное стекло длинной 1,5 метра шириной 70 см

Answer 1

1) S=1,5*0,7=1,05м^2
2)p=F/S=1200/1,05=1143Па

Answer 2

Calculating Atmospheric Pressure

To calculate the atmospheric pressure exerted on the window, we can use the formula:

Pressure = Force / Area

Given: - Force = 1.2 kN - Length of the window = 1.5 meters - Width of the window = 70 cm

First, we need to convert the width of the window to meters: - Width = 70 cm = 0.7 meters

Now, we can calculate the area of the window: - Area = Length × Width - Area = 1.5 meters × 0.7 meters - Area = 1.05 square meters

Now, we can use the formula to calculate the atmospheric pressure: - Pressure = 1.2 kN / 1.05 square meters - Pressure ≈ 1.14 kN/m²

So, the atmospheric pressure exerted on the window is approximately 1.14 kN/m².
