An electron in the 2nd excited state is trapped in a 1-d infinite square well with edges at x-o and x 0.9 nm. a. sketch the wavefunction of the electron. b. calculate the energy of the electron. c. what is the probability of finding the electron between 0 and 0.3 nm? d. the energy of the sides of the well is lowered from infinity to about 10 ev. without calculating, describe how the energy and wavelength of the electron will change and explain why these changes will occur based on the wavefunction.

That would be kinetic energy

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

The relationship of both of them
