Compare a bound electron that executes harmonic oscillations at an angular frequency of w 1015 rad/s with a 0.5 kg mass oscillating at a frequency of w/2π 1.0 hz. (a) what are the ground state energies in each case? express your answers in ev (electron volts) (b) compute the amplitude of oscillation in classical mechanics that gives the ground state energy in quantum mechanics. carry out the computation for each case in turn. comment on the physical significance of the results, e. g., in what way do the numbers you obtain make (or not make) physical sense?

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
