[#51] In a superconductor the value of critical density depends upon
Correct Answer
(D) Both A and B
[#52] The co-ordination number of a simple cubic structure is
Correct Answer
(D) 6
Explanation
Solution: In a simple cubic structure, each particle or atom is in contact with six nearest neighbors. This arrangement leads to a coordination number of 6 for a simple cubic lattice. Therefore, the correct answer is Option D: 6 .
