Aparticle in the harmonic oscillator potential starts out in the state: ψ(x,0)=a[3ψ0(x)+4ψ1(x)].(a) find ⟨x⟩ and ⟨p⟩. check that ehrenfest’s theorem holds, for this wave function. (b) if you measure the energy of this particle, what values might you get, and with what probabilities?

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

The slope of a velocity time graph over any interval of time gives the during that interval
