Given that this stands out a mile as almost certainly a school homework question, to answer directly would be to make me complicit in cheating. So I will tell you how to calculate it, which would appear to be the point of the question: 1) The relationship between depth and pressure of water is linear. 2) If water X ft deep exerts a pressure of P lb/in2, then water of Y ft deep will obviously exert a pressure of P(Y/X) lbs/in2 Given thats information you can now solve the original question.

If it has a mass of 72 kg, then its weight on earth is 705.6 newtons (about 158.7 pounds). Its size, shape, color, fabric, contents, or the pressure it exerts on the ground don't matter. Consider this: If you set the suitcase down on its bottom, on one side, or on one end, its pressure on the ground would be different in each case, but its weight would not change.

To calculate the area, we divide the force (1500 N) by the pressure (500 Pa) to get an area of 3 square meters. For the second part, if we double the area to 6 square meters and keep the force constant at 1500 N, the pressure would be halved to 250 Pa over the new larger area.

It is if a brick rests on a table the force with which the brick pushes on the table is its weight. The pressure it exerts on the contact area depends on the brick's orientation. If the contact area between brick and table is larger, the brick exerts less pressure on the contact area.

Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.

Static pressure is typically calculated using the formula P = ρgh, where P represents static pressure, ρ is the fluid density, g is the acceleration due to gravity, and h is the height of the fluid column or the depth below the surface. This formula assumes that the fluid is incompressible and that there are no velocity effects present.

Any liquid exerts equal pressure in all directions.

A fluid exerts pressure on an object immersed in it due to the weight of the fluid above the object pressing down. The pressure increases with depth as the weight of the fluid column increases, leading to greater pressure on objects deeper in the fluid. This pressure is essential for buoyancy and stability in submerged objects.

When air exerts a force, it is called air pressure. Air pressure is the force exerted by the weight of air above a given point.

Air exerts pressure because it contains molecules that are constantly in motion and colliding with surfaces around them. These collisions create a force per unit area, which results in pressure being exerted by the air. This pressure can be measured using devices like barometers or manometers.
