1. If the current density passing through the n-type 1 ohm-cm Si bar is increased to 10 4 A/cm 2 and 10 5 A/cm 2 (by reducing the cross-sectional area, what are the drift times for an electron across a 1 mm long Si b ...
The four doors problem A new game show uses rules similar to those of the three doors but there are four doors, and the host explains: ‘First you will point to one of the doors, and then I will open one of the other door ...
1. What is the input to the recursive filter such that its state sequence and the transmission are the same as those of the non-recursive filter? 2. Can you spot the most probable path and the flipped bit?
1. The equilibrium electric potential variation in an n-type Si slice of thickness L Is found to be given by V 1 (x)-V 0 + (V L -V 0 )(x/L). What are the equilibrium concentrations of electrons and holes as a function of ...
A magnetic field has a magnitude of 0.00094 T, and an electric field has a magnitude of4.3 × 103N/C. Both fields point in the same direction. A positive 1.6-μC charge moves at a speed of 3.3 × 106 m/sin a direction that ...
Fred rolls an unbiased six-sided die once per second, noting the occasions when the outcome is a six. (a) What is the mean number of rolls from one six to the next six? (b) Between two rolls, the clock strikes one. What ...
A mad doctor believes that baldness can be cured by warming the scalp with sound waves. His patients sit underneath the Bald-o-Matic loudspeakers, where their heads are bathed with 91dB of soothing 800Hz sound waves. Sup ...
A merry-go-round is at rest before a child pushes it so that it rotates with a constant angular acceleration for 32.0 s. When the child stops pushing, the merry-go-round is rotating at 1.20 rad/s. How many revolutions di ...
Wilke and Hougan 27 studied the mass-transfer characteristics of packed beds containing granular solids. In their experimental investigations, hot air was blown through a packed bed of porous celite pellets saturated wi ...
An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m 2 = 1.67 x10 -27 kg) attract each other via an electrical force. Suppose that an electron and a proton are released from rest with an initial separation d = 3. ...
