Aparticle of mass m in a 1d harmonic oscillator with frequency w, at time t = 0 is in a linear superposition of the ground and the first excited eigenstates, specifically, it has wave function 14(x,0)) - a[14) +expliq) 4.)]. (a) normalize the wave function. (b) find the coefficients cn in the series expansion 144(x,1)) - cm14(x)) exp[-i e,1/ħ]. if the energy is measured at time t, what are the possible values and what are the probabilities? find the expectation value of the hamiltonian ((x, t)|h1 4(x, t)) in this state. (c) find the expectation value of the momentum of the particle at time t, (4(x, t) p14(x, (d) find the value of the phase q such that (p) reaches its maximum value at time t=0. hint: you can take derivatives, or you can use eq. 2.69: =iħmo/2câ. - â

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
