Question

на полу стоит старинный шкаф массой 100 кг. Какое давление он производит на пол, если общая площадь опоры 5000см². СРОЧНООО, ОЧЕНЬ, ОТВЕТЬТЕ ПОЖАЛУЙСТА, ДАМ 10 БАЛЛОВ​

Answer 1

Ответ:

2000 Па

Объяснение:

Давление P = F/S, F = mg = 100*10 = 1000 Н, S = 5000 см^2 = 0,5 м^2.
=> P = 1000/0,5 = 2000 Па

Answer 2

To calculate the pressure exerted by the antique cabinet on the floor, we can use the formula:

Pressure = Force / Area

In this case, the force is the weight of the cabinet, which is given as 100 kg. We need to convert this to Newtons (N) since force is measured in Newtons. The acceleration due to gravity is approximately 9.8 m/s².

Force = mass * acceleration due to gravity

Force = 100 kg * 9.8 m/s²

Force = 980 N

The area of the support is given as 5000 cm². We need to convert this to square meters (m²) since area is measured in square meters. There are 10,000 cm² in 1 m².

Area = 5000 cm² / 10,000 cm²/m²

Area = 0.5 m²

Now we can calculate the pressure:

Pressure = Force / Area

Pressure = 980 N / 0.5 m²

Pressure = 1960 N/m²

Therefore, the antique cabinet exerts a pressure of 1960 Newtons per square meter (N/m²) on the floor.

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