How do you find the weight of a suitcase having a mass of 72kg exerts the pressure of 85Pa on the ground?

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.

What is the gravitational potential energy equation?
Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height
Why does a potato not gain or lose mass in a 4 percent concentrated salt solution?
Because the environment is Isotonic (having the same or equal osmotic pressure).
Is a meadow a plane or line segment?
The ground surface of a meadow, if completely flat, would be a part of a plane, which is a collection of points in the same 2-dimensional structure, having only length and width. A line segment would be analogous to a straight wire laid on the ground from one part of the meadow to another.
Is it true that a line on a map drawn through all points having the same temperature is called an isobar?
A line through many points with the same air temperatureis an "isotherm".The "isobar" is a line through many points with the same air pressure.
How do you convert 1gram to ml?
Grams are mass or weight and milliliters are volume, so they cannot be directly converted except for substances having the same density as water. 1 milliliter of pure water at standard temperature and pressure has a mass of 1 gram.
Why it is easier to carry heavy suitcase having wheels?
thus a exerts a greater pressure
What are symptoms of low pressure?
If you are having low pressure, you may get twist in your head and fall on the ground fainted. It is advisable to avoid raw salt in your meal, if you are having low pressure.
When you pull a suitcase with wheel why does only part of your force do work?
When you pull a suitcase with wheels, the force you apply is actually doing work only when it is in the direction of the motion of the suitcase. Any force applied in other directions, like lifting the suitcase off the ground or turning it, does not contribute to the work done on the suitcase. This is because work is defined as force exerted in the direction of the displacement.
What eight letter word having nothing to do with law is composed of two consecutive words meaning legal action?
"Suitcase".
Everyday example of air has pressure?
An everyday example of air having pressure is when you inflate a balloon. The air inside the balloon exerts pressure against the walls of the balloon, which causes it to expand and take on a specific shape. When you release the balloon, the air pressure inside forces it to deflate.
The air in the ball exerts a push on the ball so the shape of a ball can be restored is it true?
Depends on the situation, but yes, it is the air inside the ball having a greater pressure than the air outside the ball which keeps the shape.
What occurs if the air moves faster above an object than below it?
Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight. The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.
Having an osmotic pressure greater than that of the solution with which it is compared?
A solution with a higher osmotic pressure than another solution has a greater concentration of solute particles and exerts a stronger pull on water molecules across a semi-permeable membrane, resulting in water moving into the solution with higher osmotic pressure. This can cause the cell to swell or even burst if the osmotic pressure difference is too high.
How is the air pressure around a tree different from the air pressure around a plane?
The air pressure around a tree is typically stable and relatively consistent at ground level, while the air pressure around a plane varies with altitude. As a plane ascends, the air pressure decreases, requiring pressurized cabins to maintain a level of oxygen for passengers and crew.
How might habitat corridors help overcome problems with habitat fragmentation?
Any cause that reduces reproductive success in a proportion of a population, potentially exerts evolutionary pressure or selection pressure. So if a habitat changes such that certain traits lead to more or less offspring the population as a whole will have an increase in the frequency of the trait that leads to having more offspring.

Can you put makeup and toiletries in your suitcase?
If your talking airport security I've never run into any problems. I don't like having my toiletries in my suitcase directly. I always have it in a zip lock bag, just in case something busts, it doesn't get all over my clothes then.
