A balanced Y-connected load of 100 + j50 Ohm is connected to a balanced three-phase source. If the line current is 42 A and the source supplies 12kw, determine (a) the line voltage; (b) the phase voltage.
You balanced a pump impeller by placing a 5 gram weight at a radius of 100 mm. The original vibration amplitude was 10 mm/s, and after adding the balancing weight, the vibration is 1 mm/s. The speed of the pump is 1500 rpm and the weight of the im..
A cellular operator using the FDMA technique is allocated a total spectrum of 25 MHz. The system has a channel bandwidth of 60 kHz. It also uses a guard band of 20 kHz. Compute the number of channels that can be simultaneously supported in this wi..
1) Two signals are said to be orthogonal if the integral of the product of the signals is 0 over one period of the new (multiplied) signal. Assume x(t) and y(t) are orthogonal energy signals with energy, Ex and Ey, respectively.
acetic acid contains only C,Hand O.An 8.48mg sample of acetic acid is completely burned. it gives 12.42mg of carbone dioxide and 5.08 mg of water. what is the mass percentage of each element in acetic acid
A rod on the surface of Jupiter's moon Callisto has a volume of 0.3 cubic meters. Determine the weight of the rod in units of pounds-force. The desnity is 4,700 kilograms per cubic meter. Gravitational acceleration on Calisto is 1.25 meters per se..
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will also produce a minimum of two outputs, the quotient and the remainder.
Efficiency of MOSFET circuit provide in datasheets of any product is measured at transient state of my output node or staedy state?
What is the propagation constant at 500 MHz. Use the fact that the velocity of an EM wave in a lossless air-filled line is the same as that of free-space propagation in air. That is, the propagation constant is the same.
A discrete-time signal x[n] is periodic with period 8. One period of its DFT harmonic function is {X[0],...,X[7]}={3,4+ j5,- 4 - j3,1+ j5,- 4,1- j5,- 4 + j3,4 - j5}. (a) What is the average value of x[n] (b) What is the signal power of x[n]
An FM signal being transmitted is represented by eFM(t) = 50Sin((2)(95.1)(106)t+2Sin((2)(10)(103)t)). If the antenna impedance is 75 , determine: (a) total power in FM signal and (b) FM modulation index.
A temperature sensor has a static transfer function of 0.15mV/degrees C and a time constant of 3.3 s. If a step change of 22 degress C to 50 degress C is applied at t = 0, find the output voltages at 0.5s, 2.0s, 3.3 s, and 9s.
Calculate the following: A. What is the magnitude of the voltage in a wall socket if the effective voltage is 240 Vrms B. What is the magnitude of the current if the effective current is 360 mA rms
