Problem 1) Use MATLAB commands to compute the zeros of the following function y(x), over the range -10 < x < 10.y(x) = 3x3 - 12x2 - 33x + 80
Problem 2) Use a loop in MATLAB to determine how long it will take to accumulate $1,000,000 in a bank account if you deposit $10,000 initially and $10,000 at the end of each year; the account pays 6 percent annual interest.
Problem 3) The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.y(t)=7e^(-.4t)cos(5t-3)x(t)=10e^(-.5t)sin(3t+2)
Use the fact that x = 2 and y = 0 at t = 0 to determine the appropriate value of the arbitrary constant in the solution set.
a) At what time does the peak value of the AC signal occure b) What is the frequency,f,of the AC signal c) What is the period,T,of the AC signal d) At what time does the negitve peak value of the AC signal occur
Design and implement an algorithm that determines whether or not a given array of elements, list1, is completely contained within another given array of elements, list2. Consider two different scenarios: 1) both arrays are sorted; 2) both arrays a..
An n-channel JFET needs a NEGATIVE voltage applied to its GATE, relative to its SOURCE. If you have a single POSITIVE supply applied to the MASTER loop of a JFET, the mid point of the voltage divider will also be a positive voltage
Determine the relative permittivity of the dielectric, the maximum and minimum electric field intensities in medium 1 and the electric field intensity in medium 2.
A 277/480V three phase wye system has the following load: M1- Induction Motor, 50hp, n=0.91, PF= 0.89 at full load. M2- Induction motor, 25hp, n=0.9, PF= 0.9 at full load. R- Heater Load, PF=1 M- A synchronous motor to drive a second 25hp load.
A coiled tungsten wire of diameter 50um and length 10cm is glowing at a temperature of 2000°C within an evacuated light bulb. Determine the irradiance of the filament and the fraction of irradiance within the visible range of wavelength.
An LED is rated at VF=1.6V to 2.0V at IF=20mA. What value of series resistance is needed to limit the LED current to 20mA when this LED is connected to a 32 v peak source (that is, a source having a peak voltage of 32 v)
A pn junction with Nd=4x10^16 cm^-3 and Na=3 x 10^15 cm^3 experiences a reverse bias voltage of 1.6V (a) Determine the width of the depletion region and the junction capacitance per unit area
the worker's safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet above ground level. Does this arrangement violate OSHA standards for fall protection? Explain.
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
