Question

Бензин оказывает давление 2,5 кПа на дно бака. Какова высота бензина в баке? Плотность бензина 800кг/м(3). Ускорение свободного падения равно 10м/с(2).

Answer 1

800*10*h = 2500
8h=2.5
h = 2.5/8 = 0.3125 метра

Answer 2

Calculation of the Height of the Gasoline in the Tank

To calculate the height of the gasoline in the tank, we can use the equation for pressure:

Pressure (P) = Density (ρ) x Acceleration due to gravity (g) x Height (h)

Given: - Pressure (P) = 2.5 kPa (kiloPascals) - Density (ρ) = 800 kg/m³ (kilograms per cubic meter) - Acceleration due to gravity (g) = 10 m/s² (meters per second squared)

We can rearrange the equation to solve for height (h):

Height (h) = Pressure (P) / (Density (ρ) x Acceleration due to gravity (g))

Substituting the given values:

Height (h) = 2.5 kPa / (800 kg/m³ x 10 m/s²)

Converting kPa to Pa (Pascals) and simplifying:

Height (h) = 2.5 x 10³ Pa / (800 kg/m³ x 10 m/s²)

Height (h) = 2.5 x 10³ / (800 x 10) m

Height (h) = 2.5 x 10³ / 8000 m

Height (h) = 0.3125 m

Therefore, the height of the gasoline in the tank is approximately 0.3125 meters.
