Define about the Graphite Structure
Graphite is the allotropic form of carbon. In case of graphite the carbon atoms are arranged in regular hexagons in flat parallel layers and every carbon atom covalently bonds with three atoms in a this hexagonal layer. The remaining electron is delocalized among the planes forming a weak bond among the parallel layers. As the bonding between these parallel layers are weak, the layers are simply separable from each other and is the cause for softness and lubricating action of graphite.
Two thin convex lenses of focal lengths 0.15m and 0.2m are separated by a distance of 0.6m. Determine the effective focal length of the combination.
What is the type of bonding in silicon? (A) Ionic. (B) Covalent. (C) Metallic. (D) Ionic + Metallic Ans: Bonding in silicon is covalent type.
Conventional Current: Earlier scientists had no knowledge of the concept of electron, so the developed the convention, still in use, , that the direction of current is for appo
Electrostatic Induction: Electrostatic Induction is the process in which a charged object charges another neutral object without touching it.
What is ground wave?
Figure shows the transfer characteristic for an n-p-n silicon transistor.When the base current is 2.5mA, Verify (a) the value of collector current, (b) the static value of
The Phenomenon of producing a transverse emf in a current carrying conductor on applying a magnetic field perpendicular to the direction of the current is known as Hall effect.
