define a one-dimensional potential well having energies U as a function of position x as follows: U=infinity for x= -1nm to x=0; U=0 eV for x=0 to x=5nm; U=10 eV for x=5nm to x=7nm; U=0 for x>7nm and x< -1nm. We plut an electron with energy E=5eV between x=0 and x=5nm.
a) Write the schrodinger wave equation for each region in the figureb) Write the expressions for the general form of the wave function in each regionc)what are the boundary conditions and whyd) what does the graph of the wave function look like for the lowest energy levele) what is the most likely place to find a particle in this energy state?
in a given byte-addressable computer, memory location 10000Hto 9FFFFH are avaliable for user programs. the first location is 10000H and the last location is 9FFFFH. calculate the following: the total number of bytes available (in decimal)
Imagine a network layer packet that travels from one host to another host across multiple local area networks interconnected by routers, Explain how the packet moves from device to device through the network.
Prompt the user to enter a letter indicating Celsius or Fahrenheit C or c indicates that temperature entered is in Celsius. F or f indicates that temperature entered is in Fahrenheit.
Some of the particles comprising atoms react to each other in a way that scientists categorize as electric charge. There are two fundamental types of electric charge: positive and negative.
1) Determine the dynamic range for a 10-bit sign-magnitude PCM code 2) Determine the minimum number of bits required in a PCM code for a dynamic range of 80 dB. What is the coding efficiency
A 13,800/480 V three-phase Wye-Delta-connected transformer bank consists of three identical 100-kVA 7967/480-V transformers. It is supplied with power directly from a large constant-voltage bus.
A jet has 4 engines. Each engine gives a FAIL signal which is TRUE if the engine is broken, and is FALSE if the engine is working fine. The plane can fly as long as at most 1 engine is broken.
Radio Systems, In design of radio systems that incorporate wireless networks, considerations must be taken such as user access, transmission direction, switching and signal strength.
A process has dynamics G(s)=1/(4s^s+s+1). Apply a unity negative feedvack controller of the form G.c(s)=1/(s+b). (a) Report the transfer function T(s) of the closed-loop system. (b) Report T(s) to 2nd order and report the reduced transfer function T..
The purchaser of the motors is guaranteed the option of returning the defectives for repair. If the repair cost is given by 3Y^2 + Y + 2, find the expected repair cost the warehouse owner must be prepared to pay.
A process worker received an electric shock when she attempted to turn off a conveyer control. The toggle switch controlled the power to a variable speed drive. An examination found that dust had accumulated on the toggle switch. Moisture on the ..
A proportional controller for a rotating antenna has a gain Kp of 5 in-oz/deg. The antenna was initially pointing due south, but was then commanded to point southeast. What is the torque when the antenna gets to within 5o
