Die Dichte eines Materials ist in Abhängigkeit von Masse und Volumen. Das verdrängte Wasser in der Wasserglasmessung ist dabei das Maß für das Volumenäquivalent. Somit kann für jedes Material das Verhältnis angegeben werden und damit das Material über die Tabelle eindeutig abgeleitet werden.
وزن سکه +اختلاف سطح آب دراثر حجم سکه طبیعیه که باید وزن بیشتری رو نشون بده حالا اگر سکه را کاملا در آب لیوان رها کنید وزن به مراتب بالا تری رو ترازو نشان خواهد داد
I flunked out of physics, but this would never work.The volume of the water does not change. Thus the weight or volume of the coin does nothing to the displacement and does nothing to alter the weight.
With such dissimilar densities between zinc and silver you dont really need to know an exact volume. Diameter and thickness of the coin will give you a close enough approximation of volume to divide the mass by to derive density. If the coin was made out of something with a similar density as silver then knowing the exact volume would be needed
First thought fake but it's not, the coins weight is still hold by the string, but minus the displaced water. And the weight of the displayed water is displayed. Nice physics
This video proves nothing. I trust the machine that said it’s good plus the weight was spot on. The picture shown with the other metal inside was a Krugerrand. I call BS!
