Question

Банка высотой 50 см наполнена водой. Определить силу , действующую на дно банки площадью 30 кв. см. Помогите пожалуйста!!! Очень надооо!! ​

Answer 1

F=mg=ρVg=ρShg

F=1 000*0,5*30*10^-2*10=1 500 (H)

Answer 2

Calculating the Force Acting on the Bottom of the Bank

To calculate the force acting on the bottom of the bank filled with water, we can use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

Given: - Height of the water column (h) = 50 cm - Area of the bottom of the bank (A) = 30 sq. cm

First, we need to calculate the pressure exerted by the water at the bottom of the bank.

Calculating Pressure

The pressure exerted by a column of liquid can be calculated using the formula:

Pressure (P) = Density (ρ) × g × h

Where: - Density of water (ρ) = 1000 kg/m^3 (or 1 g/cm^3) - Acceleration due to gravity (g) = 9.81 m/s^2 - Height
