Answer 1

Дано:

A=2м

B=0,9м

P=10^5 Па

F-?

Формулы :

P=F/S

S=ab

F=pS=pab

Решение:

F=10^5×2×0,9=180000 Н =180 кН

Ответ: 180кН

Answer 2

To find the value of F, we can use the formula for pressure:

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

Given that: P = 10^5 Pa (Pascals) S = 45 × 10^-2 m^3 (meters cubed)

We need to rearrange the formula to solve for F:

F = P × S

Now, let's plug in the values:

F = (10^5 Pa) × (45 × 10^-2 m^3)

Now, simplify the expression:

F = 10^5 × 45 × 10^-2 m^3

F = 4500 m^3 Pa

Please note that the unit for force in the SI system is the Newton (N), which is equal to 1 kg m/s^2. The above result is in the unit of m^3 Pa, so we need to convert it to Newtons:

1 Pa = 1 N/m^2

F = 4500 N

Therefore, the force (F) is 4500 Newtons.
