The net potential energy between two adjacent ions, En, may be represented by the sum of EN= -A/r + B/rnCalculate the bonding energy E0 in terms of the parameters A, B, and n using the following procedure:1.) Differentiate EN with respect to r, and then set the resulting expression equal to zero, because the curve of EN versus r is a minimum at E0.2.) Solve for r in terms of A, B, and n, which yields r0, the equilibrium interionic spacing.3.) Determine the expression for E0 buy substituting r0 into En= -A/r + B/rn
Determine the minimum number of inverters, 2-input ANDs and ORs needed to implement each of the Boolean functions given below. If an inverter has delay of 1ns and each 2-input gate has a delay of 2ns
What degree of matching in emitter area is required for the base-emitter voltages of two bipolar devices with identical collector currents to have a difference of less than 5.0mV Use VT= 25.85mV.
Design a circuit that satisfies the equation VOUT = 5 * ( VB - VA ). Draw the circuit schematic identifying supply voltages and show your work on component selection.
A six pole, 400 V d.c. motor draws 110 A from the supply. The shunt field resistance is 200 Ohm and the armature resistance is 0.5 Ohm. The armature is wave wound with 600 conductors operates at a speed of 1200 rev/min when supplying full load.
In a particular technology, a small BJT operating at vBE = 28VT conducts a collector current of 100µA. What is the corresponding saturation current. For a transistor in the same technology but with an emitter junction that is 32 times larger
A saw, fan, and lube pump all go on when a start button is pressed. Pressing a stop button immediately stops the saw but allows the fan to continue operating. The fan is to run for an additional 5 seconds after shutdown of the saw.
Consider a gsm uplink.the ms has 100 mw transmit power and the sensitivity of the bs receiver is -105 dbm.the distance between the bs and ma is 500 m.the propagation law follows the free space law up to a distance of dbreak=50m
