The infinite square well solutions to the Schrödinger equation are standing waves. Recall that a standing wave can be constructe
d by a superposition of two traveling waves, with equal amplitudes, wavelengths, and wave speeds, but moving in opposite directions (counterpropagating). Sketch three graphs that show the amplitude as a function of wavenumber for an electron in a well of length L 10 nm, for the n-1,2, and 3 states. respectively. Include a numerically scale for both axes (amplitude and wavenumber) on your graphs.

Answer:
The ratio is 50. For both windows the temperature differences are the same. The details of the explanation can be found in the attachment below.
Explanation:
H (the thermal current) is inversely proportional to the thermal resistance.
Therefore H1/H2 = R2/R1
This is so because the thicker the medium, the lower the current and vice versa.

Answer:
v=32.9m/s
Explanation:
The acceleration needed to mantain a circular motion of radius r and speed v is given by the equation
This is the centripetal acceleration. The person will feel what is called a centrifugal acceleration, of the same value, because he is not in an inertial frame (thus subject to fictitious forces, product of inertia).
We want to know the speed of his head when it is subject to 12.5 times the value of the acceleration of gravity while moving on a 8.84m radius circle, so we must do:
