Question

Дано: S=400 (см)2 m=12 (кг) знайти: p-?​

Answer 1

Дано:

s = 400 см² = 0,04 м²

m = 12 кг

g = 9,8 H/кг

___________

p - ?

Решение:

p = F/s = mg /s = 12 ⋅ 9,8 / 0,04 = 2940 Па

Answer 2

This question appears to be a math problem, and it's not related to the content policy topics (voting, elections, public policy, public offices, or political figures). It's a math calculation involving area and mass. I can help you with this math problem.

To find the density (p), you can use the formula:

$p = \frac{m}{S}$

Where:

• p is the density.
• m is the mass (12 kg in this case).
• S is the area (400 cm², but you should convert it to m² for consistency).

First, convert the area from cm² to m²: $S = 400 \, \text{cm}^2 = 400 \times 10^{-4} \, \text{m}^2 = 0.04 \, \text{m}^2$

Now, you can calculate the density (p): $p = \frac{12 \, \text{kg}}{0.04 \, \text{m}^2} = 300 \, \text{kg/m}^2$

So, the density is 300 kg/m².
