A positively charged particle of mass 7.21E-8 kg is traveling due east with a speed of 85.3 m/s and enters a 0.340 T uniform magnetic field.The particle moves through one-quarter of a circle in a time of 2.30E-3 s, at which time it leaves the field heading due south. All duringthemotion the particle moves perpendicular to the magnetic field. What is the magnitude of the magnetic force acting on the particle?
Consider a PCM-TDM system in which 24 signals are to be processed. Each signal has a baseband bandwidth of 3 KHz. The sampling rate has to be 33.3% higher than the theoretical minimum, and 8 bits are to be used.
A balanced star load of 8+j6 O per phase is connected to three-phase, 230 V supply. Find the line current, power factor, power, reactive VA and total VA.
given analog signal : x(t)=8cos(6,000pi)+5cos(14,000pit) t>=0 sampled at rate 12,000 Hz a) sketch the spectorum of the orignal signal and the sampled signal from 0 KHz and 25 KHz.
A computer has 16-bit instructions and 64 registers. Suppose it is required to have at least 14 instructions designed to have 2 operands from registers (e.g., add, $1, $3 puts the sum of $1 and $3 into $1.
The factorial of a nonnegative integer n is written n! (pronounced "n factorial") and is defined as follows: n!= n(n-1)(n-2)(n-3)....1 (for values of n greater than or equal to 1) and n!= 1 (for n=0) for example 5! = 5x4x3x2x1,
(a) How many atoms are there in the unit cell characterizing the Si lattice (b) Verify that there are 4.994 X 1022 atoms/cm' in the Si lattice at room temperature. (c) Determine the eenter-to-center distance between nearest neighbors in the Si lattic..
A silicon NPN bipolar junction transistor is to be used as an amplifier. What are the required bias conditions for this to occur If the emitter voltage is -3V, pick an acceptable base voltage and an acceptable collector voltage for the transistor ..
Three loads are connected in parrallel across a 250 Vrms line. Load 1 absorbs 16 kW and 18 kVAR. Load 2 absorbs 10 kVA with a power factor of 0.6 leading. Load 3 absorbs 8 kW with a power factor of 1.
A dc shunt motor of 50 hp, 250 V is connected to a 230 V supply and is drawing an armature current of 200 A, and is running at speed of 1200 rpm. Its armature resistance is Ra = 0.2 ohms.
