Two identical electrons are placed in the infinite square well potential 0, 0 x a too, otherwise. consider the following perturbation h as s2, where a is a small positive real constant. also si, s correspond to the spin operators of two electrons. calculate the first order correction to the energy of the ground state of this system

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
