The subatomic particles that acts like a mini-magnet is electron. Electrons are negatively charged sub atomic particles in an atom. The electron spin is a property of an electron that makes it behave like it's spinning; a spinning electron produces a magnetic field that makes it behave like a tiny magnet in an atom.
Answer:
Electrical resistivity and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ.
The answer is d. Vacuum
Sound waves need a molecul to travel through. Gas , solid, annd liquid provide that medium.
But vacuum is just an empty space withour any moleculs in it.
Thats why in space, no one can hear you scream. Because it simply not physicsly possible
