Pressure and Density (10 points)?

We have to overcome atmospheric pressure, which varies with altitude, but at sea level

it is 101,325 pascals or 101.325 KPa. One pascal is defined as one newton per square

meter, so we need to find the area of the lid. If it's 1.2 meter wide and 0.82 meter long

its area is 1.2 times 0.82, or 0.984 sq. meter.

The atmospheric pressure at sea level is 101,325 newtons per sq. meter, and the area

of the lid is 0.984 sq. m. so the force holding it down is 101325 times 0.984, or

99703 newtons. That is slightly more than the answer you have, so perhaps the box

is at a location above sea level where the atmospheric pressure is 101,016 Pa.

Just multiply the atmospheric pressure in pascals by the lid area in sq. meters.

The water has rigidity consistent with how deep the water is. The deeper you push the try tube the extra suitable the rigidity. i believe water rigidity will strengthen via a million environment each 33 ft !
