Which of the following statements best describes how sound travels through different materials?
Sound travels faster in solids than in liquids and gases.
Sound travels as a mechanical wave that depends on how closely packed and how strongly bonded the particles of a medium are. Solids have the most closely packed particles and strongest intermolecular forces, so sound travels fastest through solids, slower through liquids, and slowest through gases.
Hence, sound travels faster in solids than in liquids and gases.

Which of the following is related to Doppler effect?
- The velocity v(x) of a particle moving in one dimension is given by v(x) = v 0 sin \(\rm\left(\frac{\pi x}{x_0}\right) \) , where v 0 and x 0 are positive constants of appropriate dimensions. If the particle is initially at x/x 0 = ϵ, where |ϵ| ≪ 1, then, in the long time, it
The position of a particle in one dimension changes in discrete steps. With each step it moves to the right, however, the length of the step is drawn from a uniform distribution from the interval \(\left[ {{\rm{λ }}\,{\rm{ - }}\,\frac{{\rm{1}}}{{\rm{2}}}{\rm{w,}}\,{\rm{λ }}\,{\rm{ + }}\,\frac{{\rm{1}}}{{\rm{2}}}{\rm{w}}} \right] \) , where λ and w are positive constants. If X denotes the distance from the starting point after N steps, the standard deviation \(\sqrt {\left\langle {{X^2}} \right\rangle \, - {{\left\langle X \right\rangle }^2}} \) for large values of N is
A particle of mass m in one dimension is in the ground state of a simple harmonic oscillator described by a Hamiltonian \(\frac{{{{\rm{P}}^{\rm{2}}}}}{{{\rm{2m}}}}{\rm{ + }}\frac{{\rm{1}}}{{\rm{2}}}{\rm{m}}{{\rm{\omega }}^{\rm{2}}}{{\rm{x}}^{\rm{2}}} \) in the standard notation.
