Question

S=150cm² m=45 кг g=9,8Н/кг p-?​

Answer 1

Ответ: 29,4кПа

Объяснение:

s=150cm²=0,015м²

m=45 кг

g=9,8Н/кг

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

p-?​

р=F/s=mg/s=45*9,8/0,015=29400Па=29,4кПа

Answer 2

To calculate the value of p (pressure), we need to know the formula relating pressure, force, and area:

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

Given: Area (A) = 150 cm² = 0.015 m² Force (F) = mass (m) * acceleration due to gravity (g) = 45 kg * 9.8 N/kg

Let's substitute the values into the formula:

p = F / A p = (45 kg * 9.8 N/kg) / 0.015 m²

Now, we can calculate the value of p:

p = (441 N) / 0.015 m² p ≈ 29,400 N/m²

Therefore, the pressure (p) is approximately 29,400 N/m².
