In theses solids the molecules or ions are arranged in a pattern.
The smallest repeating structure is called a unit cell.Thses unit cells combine to from crystal latttices.
Salt and minerals are such an example.
Thses are also called true solids
Answer:C > A > B
Explanation:
Given
Three wires A , B and C with Resistivities and lengths as given
A and L
B and 1.2 L
C and L
we know that resistance is given by
where A=cross-section of wire
It is given that common Potential is applied for three wires
Resistance of A , B and C are
Thermal Energy is given by
for same Potential difference
Thus maximum heat is generated in wire C and minimum in wire B
thus C > A > B
Answer:
B: a sand dune formed by deposition
