Calculate the conductivity from the index of refraction and the damping constant for copper (0.14 and 3.35, respectively; measurement at room temperature and λ = 0.6 µm). Compare your result with the conductivity of copper (see Appendix 4). You will notice a difference between these conductivities by several orders of magnitude. Why? (Compare only the same units!)
The masses of the three atoms are (in order) 214.9986, 210.9873, and 4.0026, all in atomic mass units. (1 atomic mass unit = 1.66 x 10-27kg = 931.5 MeV/c2.) What is the total kinetic energy of the two out coming atoms, in joules and in MeV?
Compute the probability density function of the magnitude |X| of a complex circular symmetric Gaussian random variable X with variance σ2.
Use the inverse Lorentz transformation (15.21) to re-derive the time-dilation formula (15.8). [Hint: Consider again the thought experiment of Figure 15.3, with the flash and the beep that occur at the same positions as seen in frame
design a 2 bit up/down counter using 2 d flip flops and gates such that a direction bit set to 0 causes a count up and the same "direction bit" set to 1 causes a count down. show state diagram, state table and circuit
Design a circuit for easy connection between a TTL gate and a TRIAC that uses a buffer transistor between the output port of the gate and the TRIAC. (a) In the 1st and 4th quadrants, (b) In the 2nd and 3rd quadrants.
What is the transformer used for in a full wave rectifier Can you make a bridge rectifier without a transformer What are the advantages of using a transformer If you initially have a transformer with a 1:1 ratio
The filter is to have less than 1 dB ripple in the passband compared to the response at DC. The passband is to extend to at least 16 kHz. In addition, the stopband attenuation is to be at least 65 dB, starting at the Nyquist frequency of 22.05 k..
Find the sketch the convolution of the given pairs of functions. You can use either the integration or the graphical method for convolution. x(t) = 2e-3t sin(2t) u(t) h(t) = u(t) + 4d(t-2) find y(t) = x(t) * h(t)
trace how the electrons and holes move through the device under the two different biasing conditions. Explain how these three devices work in terms ofIn a study conducted at the National Institute of Mental Health,
In a 50 mm diameter x 0.5 mm thick wafer of pure germanium at room temperature, (a) how many conduction electrons would be present, and (b) how many electron holes would be present.
To obtain this energy, you build a large nuclear reactor that can supply one gigawatt of electric power. How many years will it take to generate that energy
Using the right-hand rule, we know the magnetic field at the top of the arc is into the page and the magnetic field at the bottom of the arc is out of the page.
