The mass is changed, the density is not changed.
Yes. An object's density is an inherent property of what it is made of , regardless of how much you have. Here is another way of viewing it. Density is mass divided by volume. Two paper clips have double the mass and double the volume of one paper clip. 2m/2V=m/V
There are some articles talking about this in Wikipedia, but as I heard from my teacher who has lots of knowledge, it was invented by a child who was in school, playing with a piece of thin metal, and when he turned in his homework, he twisted it around and used it as a paperclip that's used these days. I'm pretty sure that the paperclip the child made didn't look exactly the same as today's paperclip.
probably the same size as a paperclip
The temporary magnet becomes a magnet in a strong magnetic field, but its magnetic properties will disappear when that field is taken away. The ferromagnet and the permanent magnet are essentially the same thing. The electromagnet isn't that easy to make compared to the temporary magnet. Let's conduct an esperiment. If we take a bar magnet and pick up a paperclip with it, we can use the paperclip on the end of the magnet to pick up another paperclip. The second paperclip we are picking up only needs to touch the first paperclip; it does not have to touch the magnet itself. When the magnet is taken away, the paperclips no longer exhibit magnetic properties. They were acting as temporary magnets, and the simple and easy removal of the magnet cause them to lose their magnetism.
Yes. Density only depends on the substance, not the size of the sample. A pure drop of the substance has the same density as a pure truckload of the same stuff.
2 and staples will look more professional. It wouldn't seem like you are trying to same a piece of paper. Unless the company you are applying isn't into "go green" staff. Good Luck though!
In a vacuum they would reach the ground at the same time (assuming they are released at the same time and from the same height). When not in a vacuum, however, air resistance is acting on both items - and so the paperclip would touch the ground first.
The moon's average density is about the same as the density of mantle of the Earth.
The dnsity of a submerged submarine is the same as the density of the water if the density of the submarine was grater it will sink, if the density was less it would float.
No, copper and brass doesnot have same density.
No. Density is independent of size.
No. Two objects could have the same density but they also could not. If the two objects were not made from the same substance they would not have the same density. Although if they did then they would have the same density.
