Question

Какое давление на пол производит мальчик , на который действует сила тяжести 500 Н , а площадь подошв его обуви 300см кВ

Answer 1

P=F/S=500н/0,03 м^2=16666 па=16,6 кПа

Answer 2

Calculating Pressure

To calculate the pressure a boy exerts on the floor, we can use the formula:

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

Given: - Force (F) = 500 N - Area (A) = 300 cm^2

We need to convert the area from cm^2 to m^2 before proceeding with the calculation.

Conversion of Area

To convert the area from cm^2 to m^2, we use the conversion factor: 1 m^2 = 10,000 cm^2

So, the area in m^2 is: 300 cm^2 * (1 m^2 / 10,000 cm^2) = 0.03 m^2

Calculating Pressure

Now, we can calculate the pressure using the given force and the converted area:

Pressure (P) = 500 N / 0.03 m^2

Pressure (P) = 16,666.67 Pa

Therefore, the pressure the boy exerts on the floor is approximately 16,666.67 Pascal.
