Answer: Metals
Explanation:
The metals are the conductors of electricity. These are made up of atoms which conducts electricity in the form of electrons in the outer shell that can move freely. These take away the electric charge on the entire metallic system. This way the metal conducts electricity and can also pass electricity to other surfaces if come in their contact. Thus the metals are used for creating equipment of technological importance.
#7
Given that an electron revolves in a circle and the essential centripetal force is given as
now we need to find its speed
so we know that this force is given as
#8
Here the force due to earth on satellite is the centripetal force to revolve around earth
so we can say that force due to earth is given as
we know that
now from above equation we have
The answer is it's middle the nueculs
