A particle moves on the x axis according to the equation x=x0sin2(wt). The motion is simple harmonic(1) with amplitude x0(2) with amplitude 2x0(3) with time period 2pi/w(4) with time period pi/w Please help

A particle on a speing executes shm when the particle is found at x=xmax/2 the speed of the partcle is A)vx=vmax B)vx=√3vmax/2C)vx=√2vmax/2D)vx=vmax/2

displacement associated with three dimensional wave is given by sai x y is equal to 1 + 1 by 2 x + root 3 by 2 k x minus omega t show that the wave propagates along a direction making an angle 60 degree with the x-axis

What do you mean by Energy of Simple Hormonic Motion?

What is mean by motion and time define it's all types with there parts and their s.i. units.
