Question

Самая глубокая впадина Тихого океана 10863м. Чему равна сила давления действующая на рыбу на дне этой впадины? Площадь поверхности рыбы 2,5дм (кв).

Answer 1

S=2,5 дм2=2,5*10^-2 м2;p=1030 кг/м3( морская вода); h=10863 м. Р-? Р=pgh=1030*10*10863=111888900 Па, Р=F/S, F=PS =111888900*2,5*10^-2=2797222,5 H=2,8 МН

Answer 2

The Deepest Trench in the Pacific Ocean

The deepest trench in the Pacific Ocean is the Mariana Trench, which reaches a depth of 10,863 meters (35,840 feet) It is located in the western Pacific Ocean, east of the Mariana Islands.

Calculating the Pressure on a Fish at the Bottom of the Trench

To calculate the pressure acting on a fish at the bottom of the Mariana Trench, we can use the formula for pressure:

Pressure = Force / Area

Given that the area of the fish's surface is 2.5 square decimeters (dm²), we need to calculate the force acting on the fish.

To calculate the force, we can use the formula:

Force = Pressure × Area

Since we know the depth of the trench, we can calculate the pressure at the bottom using the formula:

Pressure = Density × Gravity × Depth

The density of seawater is approximately 1,025 kilograms per cubic meter (kg/m³) The acceleration due to gravity is approximately 9.8 meters per second squared (m/s²).

Substituting the values into the formula, we get:

Pressure = (1,025 kg/m³) × (9.8 m/s²) × (10,863 meters)

Calculating this, we find that the pressure at the bottom of the Mariana Trench is approximately 106,305,135 pascals (Pa).

Now, we can calculate the force acting on the fish:

Force = (106,305,135 Pa) × (2.5 dm²)

Converting the area to square meters (m²), we get:

Force = (106,305,135 Pa) × (0.25 m²)

Calculating this, we find that the force acting on the fish at the bottom of the Mariana Trench is approximately 26,576,283.75 newtons (N).

Conclusion

The force of pressure acting on a fish at the bottom of the Mariana Trench, with a surface area of 2.5 square decimeters, is approximately 26,576,283.75 newtons (N).

Please note that the calculations provided are based on the given information and assumptions.
