Question

Сталевий кубик занурено у воду так, що його верхня грань паралельна поверхні води. Тиск води на верхню грань становить 1000 Па. Який тиск створює вода на нижню грань, якщо сила натягу нитки, за допомогою якої кубик було занурено у воду, становить 69 Н? Густина води 1000кг/м3 , сталі – 7800 кг/м3 , а коефіцієнт g=10H/кг .

Answer 1

1000 па так как масса не изменяется

Answer 2

Calculation of Pressure on the Bottom Face of the Steel Cube

To calculate the pressure exerted by the water on the bottom face of the steel cube, we can use the formula:

Pressure = Force / Area

Given that the force of tension in the thread used to submerge the cube in water is 69 N, we need to determine the area of the bottom face of the cube.

Calculation of Area of the Bottom Face of the Steel Cube

To calculate the area of the bottom face of the steel cube, we need to know the dimensions of the cube. Unfortunately, the dimensions of the cube are not provided in the question. Without this information, it is not possible to calculate the area of the bottom face of the cube and subsequently determine the pressure exerted by the water on that face.

Please provide the dimensions of the steel cube so that we can proceed with the calculation.
