I think this might be the answer, if it is I’ll be very surprised =/
Answer:
conduction electrons
Explanation:
Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions.
The middle one on the list is the correct one.
The first one ... distance divided by time ... is Speed, not force.
The third one ... mass times velocity ... is Momentum, not force.
Potential energy is defined as
here we have
mg = weight = 5 N
now for different heights we can say
U = mgh
so potential energy in all three shells will be different and increases with height
