A positively charged particle of mass 7.21E-8 kg is traveling dueeast with a speed of 85.3 m/s and enters a 0.340 T uniform magneticfield.The particle moves through one-quarter of a circle in a time of2.30E-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?
A DC machine has the following parameters: Ra =1Ω, La = 4 mH , kPWM = 100 . (a) Design the current loop with a bandwidth of 1000 rad/s and phase margin of 900. (b)Given a step current command, ia*(t) = 5u(t)A, calculate the actual current,i(t)
An electron is released from rest at a distance of 0.350 m from a large insulating sheet of charge that has uniform surface charge density 4.90×10^-12 C/m . A) How much work is done on the electron by the electric field of the sheet as the electron..
In any chemical fabrication process (eg. wet etching or CVD) there are two main regions where the reaction rate is dominated by different processes. Name them and explain what each of those regions mean.
a) determine the wave equations for all three regions b) what is K for each region c) using matrix algebra, determine the coefficients to the wave eaquation in region 2
