Because that air pressure is the same on all sides and inside objects. If you were to seal a container at the top of Mt. Everest, Then took it down to Sea Level, It might crush (depending on the strength of the container) because the air pressure inside would be much less (the same as at the Peak where you sealed it) then it is at sea level.
Air pressure can crush objects like a desk because the weight of the air above the object creates a force pushing down on it. As the air pressure increases, this force becomes stronger, causing the object to collapse under the weight.
A desk stapler is typically measured in grams, as it is a relatively lightweight object. Kilograms are usually used to measure heavier objects.
The force of your pencil or pen against the desk that your paper is on if you're writing something down. The force of your paper against the desk. The force of your book against the desk. In each case, the desk exerts the identical but opposite force against the object lying on it. If that were not true, the objects would deform the desk, or the desk would form a bump where the objects are lying on it.
A simple formula would do to get the force on the desk. Force = pressure x area. Pressure = 1 x 105 pascal. Area = length x breadth = 1.54 x 0.78 = 1.2012 m2. Hence the force = 1.2012 x 105 newton.
No, simply moving a ruler across a desk should not affect its shape. However, if the ruler is subject to excessive force or pressure during the movement, it may bend or deform.
Air pressure can crush objects like a desk because the weight of the air above the object creates a force pushing down on it. As the air pressure increases, this force becomes stronger, causing the object to collapse under the weight.
Every day objects are surrounded by air, on all sides and inside, so all the force of the weight of the air acts equally in all directions.
Answerthe reason is that the molecules in air push in all directions down,up, and sideways. The air pushing down on top of your desk is balanced by the air pushing up on the bottom of your desk.
Just leave and think of something at home or at your desk
A raven and a desk are both objects that can be found in a room.
desk
A desk, a table, a stool
Both a raven and a desk are objects that can be found in the physical world, but they are different in nature and purpose.
Some classroom objects include desks, chairs, whiteboards, markers, textbooks, calculators, and computers.
A writing desk is like a raven because both can be seen as mysterious and enigmatic objects that inspire curiosity and contemplation.
Two singular objects added together are plural, so, the book and pen are in the desk.
