Wave motion is the motion in which the particle/matter remains at the point where it is. But the disturbance/energy gets transfer from one point to the other. The particle just oscillates about its mean position. But it does not travel.
The number of electrons in an atom of an element is equal to its: (1) Atomic weight (2) Atomic number (3) Equivalent weight (4) Electron affinity Ans: Atomic weigh
Each particle produces a gravitational field around it which exerts the gravitational force on each of the other particles present within this region. The portion around a point ma
Casting : Fe-C alloys with more than 2% carbon are known as cast irons. On crossing the liquidus, proeutectic crystallizes first. On passing by the eutectic temperatures, the liqui

A solid substance has a molar volume which is smaller than that of its liquid phase. Which of the following statements regarding the solid-liquid phase transition is/are true?
A tortoise can run with a speed of 0.12 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 4.0 minutes. The torto
A particle of mass , initially moving with a speed v, collides head on ELASTICALLY with an identical particle initially at rest. a. Do you expect the total mass of the particles
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
When you are talking about relative velocity of A with respect B then it''s like you are observing the motion of A while standing on B. That is, with respect to you, B is at rest.
