Frequency
The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
V=1/T
Electric field (intensity) is a vector number. Electric field because of a positive particle is always away from the charge and that because of a negative charge is always toward
Why is the mass of a nucleus always less than the sum of the masses of its constituents, neutrons and protons? If the total number of neutrons and protons in a nuclear reaction
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
EXPLANATION: Displacement is a physical quantity which defines the motion of a body from its starting position to its final position. It is a vector quantity and can be shown b
Define Laterite stone. Laterite is called sedimentary rock. It has porous and spongy structure and can be simply quarried in blocks. It have high percentage of oxide of ion and
Hard Ferromagnetic Substances: Those substances that do not lose their magnetism or removing from magnetic field are known as hard magnetic substance such as steel.
2. Surface Crystallography and Epitaxy Fe thin films are grown on a single-crystal Al (100) substrate surface. The films grow with no dislocations (if they are thin enough) which
Write down the electromagnetic wave equation in free space, in terms of vector and scalar potential.
Derive a mathematical expression for the period of oscillation of a bar magnet in vibration magnetometer. How do you differentiate Dia, Para and Ferromagnetisms in matter.
