Carry out the same exercise as in question 16 but use the Poisson tables to determine the number of trunks required ? Give at least two queueing disciplines ? As the grade of service is improved, what is the effect on trunk efficiency? What is the basic purpose of alternative routing? What does it improve?
The end of the plates is 30 cm from the tube screen. The kinetic energy of the electrons is 2.80 keV. If a potential difference of 25.0 V is applied across the deflection plates, by how much will the point where the beam of electrons strikes the s..
