Answer:
yes it can be attracted without touching The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
Explanation:
The AZX symbol of a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+
<h3>What is AZX?</h3>
AZX is a symbol which stands for;
- A is the mass number
- Z is the atomic number or the number of protons
- X is the chemical symbol of the element
Note, cations are positively-charged ions having more protons than electrons due to loss of one or more electrons.
Sodium ion represented as Na+ is a cation which lost one electron. It has 13 neutrons and 11 protons.
But the mass number of an element, A is the sum of protons and neutrons of the element.
Thus, for Na+
A = 13 + 11 = 24
Z = 11
X = Na+
Therefore, the AZX symbol of a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+

Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is 
.
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene () = 
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene =
d = 
= 
= 
(as 1 nm = 
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
