Answer:
(d) A strong electron-phonon interaction
Explanation:
Superconductivity -
The phenomenon of superconductivity is due to the attractive force between electrons from the exchange of the phonons that cause the bound pair of electrons known as cooper pairs .
A strong electron -phonon intercation is suitable condition for superconductivity and high resistance .

Determine PCD and CPD
First, we need to calculate CPD
Since DPA is a straight line and CPA = 100;
We have that:
--- angle on a straight theorem
Substitute 100 for CPA

Subtract 100 from both sides


Next, we calculate PCD
We have that:
--alternate angle
In triangle PCD
--- angles in a triangle
Where

So, we have:


Subtract 136 from both sides


Hmmm. I think the answer is A. If I remember correctly. I had this question before. Sorry if I'm wrong.
I think the correct answer from the choices listed above is the first option. The statement that best describes the state of metals when they are at room temperature would be that most <span>nonmetals are gaseous, but some are liquid or solid. Hope this answers the question. Have a nice day.</span>
The potential difference between the two ends of the circuit is the electric potential difference. The electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.
<h3>What is an electric field?</h3>
An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
The given data in the problem is given by;
E is the electric field = (200 N/C)
d is the distance = 5.0 cm.=0.05 m
Q is the charge of electrons= 1.602 x 10^-19 C
The formula for electric potential is given by;


The work is defined as the product of the potential difference and charge of an electron.

Hence the electric potential difference and the work will be 10V and 1.6 x 10^-18 J respectively.
