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:
The angle (relative to vertical) of the net force of the car seat on the officer to the nearest degree is <u>10°.</u>
Explanation:
Given:
Mass of the driver is,
Radius of circular turn is,
Linear speed of the car is,
Since, the car makes a circular turn, the driver experiences a centripetal force radially inward towards the center of the circular turn. Also, the driver experiences a downward force due to her weight. Therefore, two forces act on the driver which are at right angles to each other.
The forces are:
1. Weight =
2. Centripetal force, 'F', which is given as:
Now, the angle of the net force acting on the driver with respect to the vertical is given by the tan ratio of the centripetal force (Horizontal force) and the weight (Vertical force) and is shown in the triangle below. Thus,
°
Therefore, the angle (relative to vertical) of the net force of the car seat on the officer to the nearest degree is 10°.
