A piston-cylinder arrangement whose piston is resting on a set of stops contains 0.5 kg of helium gas at 100 kpa and 25oC. the mass of the piston is such that a pressure of 500 kPa will just life it off the stops. Heat is added until the final volume is twice the initial volume. Assume that Helium behaves as an ideal gas. Use the table provided to determine the specific heats of helium and determine the following.
what is the amount of heat added until the piston just lifts off the stops?
Explain briefly why a capacitor can block DC voltage. How might you use this feature in a design. Explain why the impedance Zeq of a parallel RC circuit decreases as the frequency increases.
A switch-tail counter uses the compliment of the serial output of a right-shift register as its serial input. (a) Starting from an initial state of 000, list the sequence of states after each shift until the register returns to 000.
Instantaneous voltage and current of capacitor, The current flowing through a 5 F capacitor is i=3e^-2t. What is the voltage as a function of time, if the initial voltage is zero?
determining whether the number divided evenly can be accomplished by determining if there is a remainder. Implement the program using a for loop for the calculations. Additional hint: a break in the loop can make the program simpler, though it is ..
assume QPSK is the modulation method used in a digital communication system.The communication system requires minimum bit error.what is the acceptable bit error assuming additive white gaussian noise.
Show how to make a two-digit digital-to-analog converter by appropriately scaling the input resistors of a summing amplifier. The digital input represents two digits, each consisting of four lines that represent the values 1, 2, 4, and 8 for the r..
A 1.0 dc voltage source is connected across a 10 ohm resistor. What is the current through the resistor if (a) the voltage source is ideal (b) the voltage source has internal resistance 0.1 ohm (c) internal resistance 1.0 ohm
Suppose the above device is to be used as an 8-way power splitter (let's say only the top-most input is used). Let the input power be P. Assuming a cross-coupling coefficient of f and ignoring excess losses, what are the possible power levels Pi a..
Evaluate the component selection for the differentiator and integrator amplifiers and their impact on the mahematical equation for each. Items for you to consider and discuss are Do you observe any limitation factors for the component parameters an..
Water is flowing out of a tube at a near constant volumetric flowrate, V .If a graduated cylinder is used to collect a certain volume, v , of the water, and a timer is used to measure the time, t, required to collect the volume of water, the volum..
calculate inductance of sensor for air gap of 1mm and 3mm?
Early scientific researchers hypothesized that electricity was an invisible fluid that could move through certain substances. Those substances "porous" to this "fluid" were called conductors, while substances impervious to this "fluid" were called..
