One end of a long glass rod (n = 1.3) is a convex surface of radius 4.9 cm. An object is located in air along the axis of the rod, at a distance of 10 cm from the convex end. (a) How far apart are the object and the image formed by the glass rod? What is the (b) minimum and (c) maximum distance the object can be placed from the end of the rod in order to produce a virtual image?
If you have an M/M/Infinity system with arrival rate lambda and service rate mu(µ), how would you show that the expected number of packets in the queue is equal
Determine the transfer function for a second order band pass filter with specifications. Chebyschev type with 1 db ripple in the pass band Lower cutoff frequency = 100 radians/sec Upper cutoff frequency = 169 radians/sec Pass band gain = 1
Write and test a C program that outputs a waveform that switches from 10.0 kHz with a 50% duty cycle to 25.0 kHz with a 5% duty cycle every 5 seconds. Your code design must be modular - initializations and program operations are to be performed
A three phase synchronous generator operates onto a grid bus of voltage 33 kv (line to line). The armature reactance of the machine is 2 ohms per phase and the leakage reactance is 3 ohms per phase.
Suppose we want to construct a parallel plate capacitor of C= 1[F] using square plates. (a)If the dielectric is air (Xr= 1), and the plates are separated by 1 cm, what dimensions will the plates have
2) A device that responds to a small current or voltage change by activating a mechanical switch allowing a larger amount of current flow is 3) Where does a program transfer to when an interrupt occurs Interrupt vector table Interrupt service ro..
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 170-F capacitor is initially charged to 100 V
Determine the position x and the tension in the cord that is required for equilibrium. The cord passes through the smooth ring at B and has an unstretched length of 6ft and stiffness of k = 50lb/ft.
An AC motor with impedance Z = 4.2 + j3.6 O is supplied by a 220 V, 60 Hz source. Determine the time average power delivered to the load.
What does "transfer function" of a filter represent What do the Amplitude Ratio (Gain) and Phase Angle represent What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal Filter)
Experiment by changing the amplitudes of the modulating tones, and by adding a third tone to the modulating signal. First establish what you expect , then confirm by computer simulation.
A laser (wavelength fo = 633 nm) is generating a Gaussian beam with 0.1 mm beam waist (2wo). (1) Find the beam's divergence angle and depth of focus (2) What will be its diameter when it reaches Moon
