Question

What pressure is exerted on the bottom of a 0.500-m-wide by 0.900-m-long gas tank that can hold 50.0 kg of gasoline by the weight of the gasoline in it when it is full?

Answer 1

Answer:

1088.89 Pa

Explanation:

According to the Newton's second law of motion:-

$Force=Mass\times Acceleration$

Mass = 50.0 kg

Acceleration = g = 9.81 m/s²

So,  

$Force=50.0\times 9.8\ kgm/s^2$

Force = 490 N

Area of the base = $length\times breath$ = $0.500\times 0.900$ m² = 0.45 m²

Pressure = Force/Area = $\frac{490\ N}{0.45\ m^2}$ = 1088.89 Pa
