Question

СРОЧНО!!!Автомашина чинить 450 кПа. Площа опори її коліс дорівнює 0,1²м. Визначити вагу автомашини.​

Answer 1

Ответ:

Объяснение:

Р = 450 кПа = 450000 Па

S =  0,1 м^2

g = 10 Н/кг

m = ?

P = m*g/ S

m = P*S / g = 450000*0.1 / 10 = 4500 кг = 4,5 тонны

Answer 2

Calculating the Weight of the Car

To calculate the weight of the car, we can use the formula:

Pressure = Force / Area

Where: - Pressure (P) = 450 kPa - Area (A) = 0.1² m (square of the area of the tire's contact with the ground)

We can rearrange the formula to solve for Force:

Force = Pressure × Area

Now, let's calculate the force exerted by the car.

Force = 450 kPa × 0.1² m

Force = 450 kN/m² × 0.01 m²

Force = 4.5 kN

So, the force exerted by the car is 4.5
