Find the pressure at the bottom of a swimming pool that is 4.0 m deep
To find the pressure at the bottom of a swimming pool, we can use the formula for pressure:
Pressure = density × gravity × height
In this case, the height is 4.0 m. The density of water is approximately 1000 kg/m^3, and the acceleration due to gravity is approximately 9.8 m/s^2.
Pressure = 1000 kg/m^3 × 9.8 m/s^2 × 4.0 m = 39,200 Pa
Therefore, the pressure at the bottom of the swimming pool is 39,200 Pascal (Pa).
