If a particle in periodic motion moves back and forth (or to and fro) over the same path, then its motion it is called as vibratory or oscillatory. The examples of vibratory or oscillatory motion are:
1.The motion of a pendulum.
2.The motion of a spring fixed at one side, which is compressed or stretched and then released.
3.The motion of a violin string.
4.The motion of atoms in molecules or in a solid lattice.
5.The motion of air molecules as sound wave passes by.
Example 1 - A bird feeder in your yard has a total mass of 3.0 kilograms and is supported as shown. What is the force on the top wire? The bird feeder is not falling so the forc

Mach number is the ratio of velocity of source to the velocity of sound. Mach Number = Velocity of Source / Velocity of Sound .
Q Define: mobility. Give its unit. The mobility is defined as the drift velocity obtains per unit electric field. The unit of a mobility m 2 V 1s 1.
If the angle of incidence is 60 degrees,then what is the angle of deviation?
Choroid: Inside the sclera it is thin, non transparent or opaque. Its front part of iris there is an aperture known as the pupil which control amount of light entering the eye.
Voltage division: In a series circuit Ohm's law applies for each component. However, since the current is common to all components we have: V1 = IR1, V2 = IR2,
