Question

3. Давление стола массой 50 кг на пол равно 1кПа. Чему равна площадь его основания?

Answer 1

Ответ: 0,5м²

Объяснение:

Дано:

m=50кг

Р=1кПа=1000Па

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

P=F/S

Отсюда S=F/P=mg/P=50*10/1000=0,5м²

Answer 2

Calculating the Area of the Table's Base

To calculate the area of the table's base, we can use the formula:

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

Given: - Force (F) = 50 kg - Pressure (P) = 1 kPa

We need to find the Area (A).

Calculating the Area:

Using the formula, we can rearrange it to solve for the area:

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

Substitute the given values: - Force (F) = 50 kg - Pressure (P) = 1 kPa

Area (A) = 50 kg / 1 kPa

Now, we need to convert the units to ensure they are consistent. Since 1 kg = 9.81 N and 1 kPa = 1000 N/m^2, we can convert the units:

Area (A) = (50 kg * 9.81 N/kg) / (1 kPa * 1000 N/m^2)

Area (A) = (490.5 N) / (1000 N/m^2)

Area (A) = 0.4905 m^2

So, the area of the table's base is 0.4905 square meters.
