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

1088.89 Pa

Step-by-step explanation:

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

`Force=Mass* Acceleration`

Mass = 50.0 kg

Acceleration = g = 9.81 m/s²

So,

`Force=50.0* 9.8\ kgm/s^2`

Force = 490 N

Area of the base =
`length* breath` =
`0.500* 0.900` m² = 0.45 m²

Pressure = Force/Area =
`(490\ N)/(0.45\ m^2)` = 1088.89 Pa
