Assertion (A): Atomic number of sodium is 11.
Reason (R): Sodium has a body centred cubic lattice.
Atomic number is not dependent on lattice structure.
In paramagnetic materials
In paramagnetic materials interaction between neighbouring dipoles is negligible.
Above ferroelectric curie temperature, spontaneous polarization in ferroelectric materials becomes stronger.
Spontaneous polarization vanishes above ferro-electric Curie temperature.
Which capacitor-store higher amount of energy?
Energy stored is proportional to capacitance and capacitance is proportional to permittivity.
Diamond is a paramagnetic material.
Diamond is diamagnetic.
