Question

давление, которое создаёт тело на опору площадью 0,15м квадратного вавно 2,5 кило паскаля найти массу тела​

Answer 1

Дано:

p=2,5 кПа=2500Па

S=0,15 м^2

g=9,8 Н/кг

m-?

F=mg->m=F/g

p=F/S->F=p/S

m=p/S/g=p/Sg

m=2500/0,15×9,8≈1700,7 (кг)

Ответ:m≈1700,7 кг

Answer 2

Calculating the Mass of the Object

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

Pressure = Force / Area

Given: - Pressure = 2.5 kilopascals - Area = 0.15 m^2

We can rearrange the formula to solve for force: Force = Pressure × Area

Let's calculate the force first.

Force = 2.5 kPa × 0.15 m^2

Force = 0.375 kN

Now, we can use the formula: Weight = Mass × Acceleration due to gravity

Given: - Acceleration due to gravity = 9.81 m/s^2

We can rearrange the formula to solve for mass: Mass = Force / Acceleration due to gravity

Let's calculate the mass.

Mass = 0.375 kN / 9.81 m/s^2

Mass ≈ 0.038 kg

So, the mass of the object is approximately 0.038 kg.
