The pressure at the bottom of the ocean is great enough to crush submarines with steel walls that are ten centimeters thick. Suppose a submarine is at a depth of 1,000 meters. The weight of water above each square
meter of the submarine is 9,800,000 newtons.

9800000N/m²

Explanation:

Given parameters:

Depth of the submarine  = 1000m

Weight of the water above  = 9,800,000N per unit area

Unknown:

Pressure  = ?

Solution:

The pressure at this depth is the force or weight per unit area.

    Pressure  =  

    Pressure  =  

    Pressure  = 9800000N/m²

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
