a sample of 0 385 gram of cus was formed by heating a mixture containing 0.318 gram of copper and 1.00 gram of sulfure according to the reaction , Cu + S ---> CuS.
A) is copper or sulfer the limiting reactant ? Explain
B) calculate the theoretical and the percent yield of Cus.
How would you develop a looping program in MIPS that will take a series of decimal numbers and arrange them in ascending order from smallest to largest. The sequence of nine numbers are: 5, 3, 8, 9, 2, 4, 1, 7, 6, 3, 8
A voltage divider is required to produce a 5.5 v output from a 12 v source. If one of the resistor values is 1.0 k, what value is required for the second resistor so that the voltage across the 1.0k resistor is 5.5v
Suppose you are designing a power amplifier for a loudspeaker which has an equivalent resistance of 150 . What should be the Thevenin equivalent resistance of the power amplifier in order to maximize the power transfer to the loudspeaker
The motor resistance is 0.5ohm and the magnetic circuit may be assumed unsaturated. What will be the speed if: (i) the load torque is increased by 44%, (ii) the motor current is 10A
A designer searches for a simple circuit to provide one-third of a signal current I to a load resistance R. Suggest a solution using one resistor. What must its value be. What is the input resistance of the resulting current divide
(b) Calculate the power dissipated in the MOSFET when the lamp is operating at its rated current. (c) The maximum output current available from the logic system is 30mA. Explain why an NPN transistor would be unsuitable for this appli..

The length of GaAs laser resonator is L = 165 um; the width and the thickness are W = 10 um and d = 0.1 um. Find the photon round-trip time in this resonator. The refractive index of GaAs is 3.7.
Current Pulses over a Twisted Pair Telephone Line, A twisted pair telephone line has a constant attenuation between 0 Hz and 3300 Hz and linear phase shift with frequency
determine the transfer function of a 4th order lowpass butterworth filter with a 3-dB cutoff frequency of 3.4 kHz and passband gain=1. Design the circuit using MFB topology. Design two sections with an order of 2.
explain the use of the Op Amp as a difference amplifier and as a comparator. What are the distinctions between the ways each one is used.
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
