Problem 2: A particle with charge q is emitted from the origin with momentum p directed at an angle ? to a uniform magnetic field B which lies in the z-direction. i) What is the position of the particle as a function of time? ii) At what point does the particle next intersect the z-axis?

Implement a 2 by 2 multiplier using structure VHDL. The circuit will have two 2-bit unsigned inputs (A and B), a 4-bit unsigned product outputs (P). you must use some full adders and gates (AND, OR, NOT, XOR).

The subject is rigid body motion.

MATLAB is ok to use.

Research and discuss the similarities and dissimilarities of several types of PLCs, i.e. pneumatic, hydraulic and electric. Include in your discussion examples of each and situations where one type is better used than the other. Your comments should be 100 words or more and include a citation.

a. Represent 2.25 in fixed point form with 4 bits for the integer portion and 4 bits for the fractional point.

b. Represent-1.75 in the same form

c. Now add 2.25 with-1.75 in the fixed point form

question#1: Write instructions to toggle bits Bit0 of PORTB assuming the PORTB is already initialized as an output port.

question#2: The following unsigned integer readings are stored in data register starting from REG10 (address 10H). Data (H): 40, 45, 4A, 32, 52, 38, 3A, 44 Write a program that finds the average temperature. Simulate your program in PIC18 IDE Simulator and attach a screenshot of your simulation while the program is running.

1)      Do linear regression (includes line, r-coefficient) for data taken from a thermocouple during calibration for:

4) Write equations that could be programmed into a controller for the following conversions: a) 4-20 mA to 0 to 100 gallons b) 0-10V to 0 to 100 gallons c) 4-20mA to 50 to 500 pounds d) 4-20mA to 13 cfm to 26cfm (gas flow)

Calculate all of the energy levels for an electron in the finite potential well of width a) L = 10 Å, b) L = 50 Å, c) L = 100 Å and L = 1000 Å using the actual mass of an electron for the conduction band of the AlGaAs/GaAs/AlGaAs quantum well. Repeat problem using a) the effective mass of an electron in GaAs (electron effective mass meff = 0.067*mass of an electron)

how to design a butterworth filter based on magnitude. Please give a numerical example. Assume only passband frequency and magnitude level is given, nothing else at all.

1. Using Moore machine approach design a sequence detector with one input and one output. When input sequence 010 occurs the output becomes 1 and remains 1 until the sequence 010 occurs again in which case the
output returns to 0. The output remains 0 until, 010 occurs the third time, and so on. Your design should be able to handle overlapping sequences, i.e., input sequence 11001010100 should produce the output 00000110011.
Implement your detector using D flip-flops and the combinatorial gates of your
choice in Behavioral Verilog. Design a behavioral test
circuit which generates the test sequence shown above: ”11001010100”.

An SCR (silicon-controlled rectifier) is frequently used as a switch of AC currrent. If you saw a schematic of a circuit of an AC power heater tha SCR controller, so that if the heater was controlled from 0 to 100% single phase, how many SCR's would you typically expect to see in the circuit.

a. one

b. two

c. three.

You see Solid State Relay in a cabinet controlling an AC Circuit. A key difference in troubleshooting this device over a standard contact relay is ...

a. A solid state relay will normally show off -state leakage

b. Measurements will show a on-state voltage drop across the contacts

c. Both a and b.

A photo diode is commonly used as a light sensor. This device functions because.

a. light reduces the forward bias resistance

b. light increases the forward bias resistance.

c. heat from the light cause eletron flow.

A solid state relay is switching 50 Amps. The relay is using Triac whose on -state voltage drop is 2 Volts. The power supply is 120VAC. Using the formula Power = Volts x Amps, calculate the power (heat) that needs to be disipated by this relay when it is conducting.

a. 50 watts

b. 100 watts

c. 10 watts.

You have a light producing 2073 lumens at 1 ft, a surface 4 feet away should receive ____ footcandles per sq. foot.
