Question

Найти массу тела, если оно оказывает давление 40000 Па(паскаль) и его площадь 13000 см3(сантиметры кубические)

Answer 1

Ответ:Основные формулы:

P=F/S

F=mg

Найдем F:

F=PS=400*0.05=20 Н

Теперь найдем m:

m=F/g=20/9.8=2 кг (Примерно)

Ответ: 2 кг

Answer 2

Calculating the Mass of the Object

To calculate the mass of the object, we can use the formula:

Pressure = Force / Area

Where: - Pressure (P) = 40000 Pa - Area (A) = 13000 cm^3

First, we need to convert the area from cubic centimeters to square meters, as pressure is given in pascals (N/m^2). Then we can use the formula to find the force, and finally, calculate the mass using the formula:

Mass = Force / Acceleration

Let's proceed with the calculations.

Converting Area from Cubic Centimeters to Square Meters

The area is given as 13000 cm^3. To convert this to square meters, we need to divide by 1000000 (since 1 m^2 = 1000000 cm^2).

13000 cm^3 = 13000 / 1000000 m^2

13000 cm^3 = 0.0013 m^2

Calculating Force

Now, we can calculate the force using the formula:

Force = Pressure × Area

Force = 40000 Pa × 0.0013 m^2

Force = 52 N

Calculating the Mass

Finally, we can calculate the mass using the formula:

Mass = Force / Acceleration

However, the acceleration is not provided in the question. If the acceleration is known, we can proceed with the calculation using the above formula.

If the acceleration is not provided, we can't calculate the mass without this information.

If you have the acceleration value, please provide it, and I can help you calculate the mass.
