which of a papers has a greater surface area flat sheet of papaer or a crumpled sheet of paper?
The surface area of a sheet of paper is that two-dimensional boundary of the paper that is exposed to the outside surroundings.
For example: Assume the surface area of a sheet of paper of area size a is A = 2a because there are two distinct surfaces (e.g., front and back) exposed to the surroundings.
But now we fold the sheet into half. So now the surface area exposed to the surroundings is 1/2 a X 2 = a < A.
In other words, by folding the paper in half we have reduced the surface area by one-half. If we simply extend that thought to include crumpling a piece of paper as meaning creating lots of folds it is reasonable to assume that the amount of area exposed to the outside will be reduced.
In other words, the surface area of a crumpled piece of paper will be less than or equal to the same area of the uncrumpled piece. But generally and typically it will be less than the uncrumpled area. ANS

How does a thumbtack work?
A thumbtack works by pressing the sharp end into a surface to secure papers or other items in place. The flat end of the tack provides a surface for pressing with your thumb or a similar tool to push it into the material.
What happens when the student uses a straw to blow a stream of air between the papers?
When a student uses a straw to blow a stream of air between two papers, the difference in air pressure causes the papers to move apart. This is due to the Bernoulli principle, which states that as the speed of a fluid (in this case, air) increases, its pressure decreases. The faster-moving air between the papers creates lower pressure, leading to the papers separating.
What happens when the student uses a straw to blow a stream of air between papers?
When a student uses a straw to blow a stream of air between papers, the fast-moving air creates an area of low pressure between the papers. This causes the papers to move closer together as the higher pressure outside the stream pushes them inward.
Albert Einstein papers of 1905?
In 1905, Albert Einstein published four revolutionary papers that significantly impacted the field of physics. These papers introduced the theory of special relativity, explained the photoelectric effect, proposed the existence of atoms, and derived the famous equation E=mc^2. The ideas presented in these papers laid the foundation for modern physics.
What are some examples of printed materials?
Some examples of printed materials include books, magazines, newspapers, brochures, posters, and flyers.
Do two pieces of paper one crumpled the other not fall at the same rate and explain?
They do not. Since a crumbled and an uncrumbled paper has the same weight but not the same surface area they will have the same gravitational pull but the difference in surface area give them diffent air resistance. Air resistance is the force when the paper have to move the air molecules while falling. Since the unfolded paper have to move more molecules because of its bigger surface, it will move slower through the air since the papers have the same gravital pull and therefore the same amount of force moving them downward.
What if diamonds has papers?
If by 'papers' you mean documentation:Every diamond is unique in its colour, clarity, carat weight and cut. Certificates specify each characteristic for the diamondIf by 'papers' you mean containers:Loose diamonds are held in folded papers, so that they are not lost -- they are extremely valuable for their size -- and so that there is a writing surface upon which to note details -- as above -- about the diamond folded therein.In both cases, diamonds with 'papers' are preferred.
Staple what is the meaning of the word?
The meaning of the word staple is a short metal that is bent. It is driven into a surface to keep items together such as a group of papers.

What is the diferece between recycled paper and recycling papaer?
Although the quality of non recycled papers is better than that of recycled ones, I would prefer the recycled ones . We can perform the rough works on these papers. At least ,this little effort made by us could save hundreds of trees!

He contributed only five of the essays--in part because of illness, but largely because of Madison's and Hamilton's greater gift for the enterprise.
