Question

Для спостереження рослинного і тваринного світу морів або оке- анів використовують товстостінні металеві кулі з ілюмінатора- ми — батисфери. Який тиск створює вода на поверхню батисфе- ри на глибині 1 км? З якою силою тисне на цій глибині вода на батисферу, якщо площа її поверхні дорівнює 1,1 м, а густина кг морської води 1030 ? M​

Answer 2

To observe the plant and animal life in the seas or oceans, thick-walled metal spheres with illuminators called bathyspheres are used. The pressure exerted by water on the surface of a bathysphere at a depth of 1 km can be calculated using the formula for pressure: pressure = density × gravitational acceleration × depth.

Given that the density of seawater is 1030 kg/m³, the depth is 1 km (1000 m), and the gravitational acceleration is approximately 9.8 m/s², we can calculate the pressure.

Calculation:

Density of seawater (ρ) = 1030 kg/m³ Depth (h) = 1000 m Gravitational acceleration (g) ≈ 9.8 m/s²

Using the formula for pressure: pressure = density × gravitational acceleration × depth

Substituting the given values: pressure = 1030 kg/m³ × 9.8 m/s² × 1000 m

Calculating the pressure: pressure = 10,094,000 Pa (Pascals)

Therefore, the water exerts a pressure of approximately 10,094,000 Pascals (Pa) on the surface of the bathysphere at a depth of 1 km in the ocean.

Please note that this calculation assumes a constant density of seawater and does not take into account other factors such as temperature and salinity variations, which can affect the density of seawater at different depths.
