When a certain perfect gas is heated at constant pressure from 15 oC to 95 oC, the heat required is 1136 kJ/kg. When the same gas is heated at constant volume between the same temperatures the heat required is 808 kJ/kg. Calculate Cp, Cv, R and the molar mass of the gas.
The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
A "ferrite" having a relative permeability of 50 H / m, that operates with flux densities sufficiently small, may be considered a single material. If the magnetic flux density in the material is B = 0.05 T, H and M. halle How to compare the values
Derive the Buck-Boost equation by which you can find the Inductance, Resistance, and capacitance
At some instant, it goes into regenerative braking. Calculate the armature voltage va at that instant, if the current ia is not to exceed 10A in magnitude. Assume that the inertia is large and thus the speed changes very slowly.
A baseband signal has frequency components from 5 kHz to 15 kHz. Determine (a) the theoretical minimum sampling rate and (b) the maximum time interval between successive samples.
a) Describe the components and variables of the biological control apparatus involved in walking toward an object that can be seen on the horizon b) Why is walking a closed-loop operation
A discrete-time signal x[n] is periodic with period 8. One period of its DFT harmonic function is {X[0],...,X[7]}={3,4+ j5,- 4 - j3,1+ j5,- 4,1- j5,- 4 + j3,4 - j5}. (a) What is the average value of x[n] (b) What is the signal power of x[n]
Consider a GaAs MESFET. When the device is biased in the saturation region,Id=18.5 micrroamp,Vgs=.35 and Id=86.2 micro amp,Vgs=.5 determine the conduction parameter and k and threshold voltage Vth
The characteristic equations for a D flip-flop determine that the output Q is updated to either 0 or 1 after each clock cycle. A loadable D flip-flop has one additional input Load that allows data to be stored in the flip-flop for more than a sing..
Given two NPN BJTs having b = 100 and ro = 100 KW. Using a single 5V dc power supply, design a differential pair amplifier having 1mA bias current in each transistor. What is its maximum gain for linear operation (balanced input, unbalanced output..
There are two printers and two I/O ports available in a system. Process A is using an I/O port and is waiting for a printer. Process B is using a printer. Process C is using a printer and is waiting for an I/O port.
a low pass first order instrument has a time constant of 20ms. Find frequency in hz of the input at which the output is 93% of dc output. Find phase angle.
