Question

7. Рыба находится на глубине 900 м 1) вычислить давление воды на рыбу (плотность воды равна p = 1000 кг/м³) 2) вычислить силу давления на рыбу, если площадь поверхности рыбы 0,2 м²​

Answer 1

Ответ: 9МПа; 1,8МН.

Объяснение:

Дано:

h=900м

ρ = 1000 кг/м³

S=0,2м²

---------------------

р-?; Р-?

р=ρgh=1000*10*900=9000000Па=9МПа

Р=рS=9000000*0,2=1800000Н=1,8МН

Answer 2

Calculation of Water Pressure on the Fish

To calculate the water pressure on the fish at a depth of 900 m, we can use the formula:

Pressure = Density × Gravity × Depth

Given that the density of water is 1000 kg/m³ and the depth is 900 m, we can substitute these values into the formula:

Pressure = 1000 kg/m³ × 9.8 m/s² × 900 m

Calculating this expression gives us the water pressure on the fish.

Calculation of the Force of Pressure on the Fish

To calculate the force of pressure on the fish, we need to multiply the pressure by the surface area of the fish.

Given that the surface area of the fish is 0.2 m², we can use the formula:

Force = Pressure × Surface Area

Substituting the calculated pressure and the given surface area into the formula, we can calculate the force of pressure on the fish.
