Question

M-8кг P-2•1000Па S-?

Answer 1

S=F÷p

F=m×g=8кг×10кг/м^3=80Н

S=80H÷2000Па=0,04м^2

Answer 2

To calculate the missing value, we can use the formula for pressure:

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

where: M = Mass = 8 kg P = Pressure = 2,000 Pa S = Area (unknown)

We need to find the value of S (Area). To do that, we rearrange the formula:

S = F / P

We know that Force (F) is equal to the product of mass (M) and acceleration due to gravity (g), where g ≈ 9.81 m/s² on Earth's surface.

F = M * g

Substitute the given values:

F = 8 kg * 9.81 m/s² ≈ 78.48 N

Now, calculate the area (S):

S = F / P S = 78.48 N / 2,000 Pa ≈ 0.03924 m²

So, the area (S) is approximately 0.03924 square meters.
