1. Discuss briefly the motional emf concept.
2. What is Lenz's law?
3. How would you orient a loop antenna in order to obtain maximum signal from an incident electromagnetic wave which has its magnetic field linearly polarized in the north-south direction?
4. State three applications of Faraday's law.
Define and describe fuzzy logic, genetic algorithms, and intelligent agents. Explain how each works and the kinds of problems for which each is suited.
Let x(n) be the input signal to a discrete-time filter with impulse response hi(n) and let yi(n) be the corresponding output. These sequences are written such that the first value islocated at instant n=0. (a) Plot x(n) and y1(n).
Assume the flow to be laminar. Find the pressure rise and efficiency as a function of the flow rate per unit depth.
An office worker wants to plug in a 3000 watt 110 Volt heater into a standard 15 amp, 110 V electrical outlet. Would this be safe
The current density inside a long solid cylindrical wire of radius a is in the direction of central axis and varies linearly with the distance from that axis r according to J=J0 r/a.
Obtain the input impedance by replacing the linear transformer by its T equivalent.
Calculate the magnitude and phase angle of the current through the coil, and the magnitude and phase angle of the voltage across the coil. Also, calculate S, P and Q for the circuit
A uniform electric field of magnitude 690 N/C exists between two parallel plates that are 3.88 cm apart. A proton is released from rest at the positive plate at the same instant an electron is released from rest at the negative plate.
The subatiomic research that can be conducted using particles and radiations from naturally radioactive substances is limited becuase the radioactive emissions:
Two identical 138 kV Y: 13.8 kV DELTA 100 MVA tap changing transformer each with a per unit series impedance of j.1 ohms are operating in parallel and supplying a 180 MVA load at 13.8 kV and .8 lagging pf.
A constant(dc) current i(t)=3mA flows into a 50x10^(-6) capacitor. The voltage at t=0 is v(0)= -20V. The references for v(t) and i(t) have the passive configuration. 1. find the power at t=0 2. state whether the power flow into or out of the capaci..
Signal transduction refers to any process of changing one signal to signal of another type. An example would be a series of pulsing lights into the sound for the word: "Help". Discuss how this transduction could be done by a device.
