A quantum well has a finite-height barrier on one side and an infinitely high barrier on the other. Find the energies for the two lowest states for an electron in the well. The width of the well is L = 1 nm and the height of the finite step is Uo = 1 eV.
It is possible that such a well may not have any bound states at all. Come up with a mathematical expression for the condition that there will be at least one bound state in the well. Your expression should relate Uo and L, along with any other necessary physical constants.
A somewhat discharged automotive battery has an open-circuit voltage of 12.5 V and supplies 50 A when a 0.1-? resistance is connected across the battery terminals.
A 50HP single phase motor operates from a 480V, 60HZ supply. When delivering full rated power the motor efficiency is 89% and the power factor is 0.78 lagging. Determine the full load current.(Hint: 746W=1HP)
1. Calculate the total (composite) load power factor, true power, reactive power and apparent power. 2. Also calculate the full-load current and the amount of capacitive KVAR needed to bring the overall power factor to .95 lagging.
(1) In a lab experiment on parallel Resonance circuit with switch closed, What is the phase relationship between Ic and IL at Is minimum (2) Why is the source current , Is, minimum at a given frequency
the Mars Rover Spirit got stuck in the Martian sand. The wheels kept slipping. Attempts to free it were futile. Discuss the type of actuator in this case. Can you suggest any improvements in the actuator that would have prevented this unfortunate ..
A 1900x10^(-6)F capacitor, intially cahrged to 120V, is discharged by a steady state of 120x10^(-6)A how long does it take to discharge the capacitor to 0V
create a graph showing the relationship of an ideal gas between pressure (P) and temperature (T). The ideal gas law relates the pressure, volume, amount, and temperature of an ideal gas using the relationship: PV = nRT.
The power transfer in a transmission line is governed by the equation P = VS * VR * sin\(\delta\)/X line. Basedon this equation what is the maximum power transfer that can be achieved, and what is its value if VS =VR = 1.0p.u
The power supplied by a certain source is a constant 7.5 W over the first 5.8 min, zero for the next 2.8 min, a value that increases linearly from zero to 10 W during the next 8.8 min, and a value that decreases linearly from 10 W to zero
If you have 16 kibibytes of memory plus a few (less than 10) memory mapped devices (assume that each device uses 16 bytes of address space), what should the address size be
Write C code that senses 3 accelerometer readings into pins PAD 8, 9 and 10 and displays them on the LCD. Also run a timer in seconds and log the values of the accelerometers in 3 arrays every second.
A transmitter operates with a carrier frequency of 2.0 MHz. It is amplitude modulated by two tones with frequencies of 1300 and 2300Hz. What frequencies are present in the output signal
