The density of sample is 5 g/cm3

Given:

volume of sample = 20 cm3

mass of sample = 100 grams

To Find:

density of sample

Solution: Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume

density = mass/volume

d = 100/20

d = 5 g/cm3

So, density of sample is 5 g/cm3

What is the suprising thing that happens in a superconductor
ololo11 [35]
One of the most surprising things about a superconductor is that
it has NO electrical resistance. The resistance doesn't just become
very very very small.  It becomes literally completely zero. (This is
a big part of the reason why it's called a "super-conductor".)

If you start an electric current flowing in a superconductor, you can
connect the ends of it together, and the current keeps going around
and around the loop and never dies out !
