A ton of wool and iron. What is harder?
Bashny.Net
Beaten seemingly question: What is heavier?
Like a ton of it and have a ton. but not so simple.
Instruments for measuring the mass does not exist, there are only scales measure weight. Let's put on large scales ton ton of iron and wool. Counterbalance, noted in a notebook "equal." Now share a bunch of wool and iron beams, for example, for 1000 equal parts, respectively. Weighed individually, and that we find? The total weight of wool significantly more. Hmm ... how so?
Remembering school physics, the laws of Archimedes. And barely remember, or look in a directory that Archimedes force acts not only in liquids and in gases. Weak, of course, but it is. The air is a gas mixture of gases, and the law it works. The greater the volume, the greater the force of Archimedes directed strictly against gravity, which scales and measured. And since the volume of the heap of cotton weighing 1 ton of a lot more volume tons of iron, hence the discrepancy. like that.
