A substance which allows energy (heat or electricity) to pass through it is known as a conductor.
These substances usually have free electrons which allows the charges to flow easily in the substance, thus, transferring energy.
Other substances which do not have free electrons and do not allow energy to pass through them are known as insulators.
Im going with c hope this helps
The correct answer should be "longer than".
I believe it is low frequency.
D) O-O
The higher the difference in electronegativities of the two atoms, the more polar it is. Although oxygen is a very electronegative atom, it is bonded to itself which would make it a nonpolar bond.
