Physics
1 answer:
LekaFEV [45]3 years ago
5 0

Answer:

The answer is letter D.

Explanation:

Electricity is the flow of electrons in a material in a specific direction. When we connect a differential potential between a conducting material, all valence electrons (the electrons which are in the outer shell of the electronic configuration of the atom) must move freely through the atom. This is the definition of a conducting material.

By the other hand in insulating materials, the valence electrons are bound tightly to their atoms, impeding the movement of the electrons due to the differential potential.

Therefore the answer will be letter <u>D</u>, electricity will flow if the electrons are bound loosely to their atoms in the material.  

I hope it helps you!

Explain how a star's absorption spectrum and the concept of red shift help support the Big Bang Theory.
marta [7]

Answer:

Red shift supports the big bang theory. ... The light from distant galaxies is red shifted (this tells us the galaxies are moving away from us) and the further away the galaxy the greater the red shift (this tells us that the more distant the galaxy the faster it is moving). Constellations look like they are moving because earth is rotating on it's axis.
