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?

tbh i dont know ether

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
