An experimentalpackage and its support structure wh ich are to be place on board a space station act as an underdamped spring - mass system w ith a force constant of 2.1X106N/mand mass 108kg. A requ irement is that resonance for forced oscillation notoccurs for any frequency below 35 Hz. Does this package meet the requirement?
In the differential amplifier shown in the schematic, R1 = R2 = 10 k ohm; R3 = R4 = 100 k ohm. Assume the ECG voltage at V1 = 100 mV, and the ECG voltage at V2 = - 100 mV. There is a power line interference of 200 mV at both input sites.
A three-phase induction motor operates at a slip of 3% and has a rotor copper loss of 300W. The rotational loss is 1500W. Determine (a) The air-gap power (b) The power output (c) If the rotor impedance is 0.2+j0.8 ohm/phase,
silicon is doped so that 1 in 10000 Si atoms is replaced by phosphorous atoms. A) Knowing that only 30% of the phosphorous atoms donate electrons at room temperature (30% ionization) , determine the effective doping level and electron concentratio..
The expression for the torque of an induction motor as a function of its slip may be obtained by application of Thevenin's theorem to the circuit model. Show that the Zth obtained can be shown to be approximately equal to Zth = R1+JX1

The voltage drops across three resistors in series are measured to be 10.0V, 15.0V, and 25.0V. If the largest resistor is 47.0ohm, what is the value of the smallest resistor
The current is the flow of electrons through conductor ,and voltage is the force that exerted on electrons to flow through the conductor, then why in many electric circuit the voltage is very high while current is less or vice-versa.
A 64K x 16 RAM chip uses coincident decoding by splitting theinternal decoder into row select and column select. (a) Assumingthat the RAM cell array is square, what is the size of eachdecoder, and how many AND gates are required for decoding an ad..
A submarine uses a λ/2 -dipole antenna for RFcommunications with the Naval Command Control and OceanSurveillance Center that also equipped with a λ/2-dipole. Operating frequency is 30 MHz. Find the length of both antennas.
John's house is served electrically by a single phase transformer rated 15 kVA, 8160 / 220 V, 60 Hz. The leakage reactance of the transformer is 400 ohms referred to the high side. John wants to replicate an interesting EEE 360 experiment
