The expression for the torque of an induction motor as a function of its slip may be obtained by application of Thevenin's theorem to the circuit model. Show that the Zth obtained can be shown to be approximately equal to Zth = R1+JX1, where X1=X1 and
R1= r1(Xm/(X1+Xm))^2.
Find the expression for the slip at which maximum torque occurs and the expression for the subsequent maximum torque at the maximum slip. Please show all calculations for the exact expressions explicitly. List your assumptions and rationale for aprroximations used.

(b) If the molecular weight of bombykol is 238.4 amu, what is the molecular formula (c) If 5.698 g of bombykol is burned in excess oxygen to form 16.83 g of CO2 and 6.452 g of H2O, how many grams of carbon were present in the original sample
A 50 ohms lossless transmission line is to be connected to a load of 25 ohm. Use a lamda/4(quarterLamda) length of line of unknown impedance between the load and the 50-ohm line to match it,
A quantum well has a finite-height barrier on one side and an infinitely high barrier on the other. Find the energies for the two lowest states for an electron in the well. The width of the well is L = 1 nm and the height of the finite step is Uo ..
Suppose 33 mL of 1.20 MHCl is added to 42 mL of a solution containing excess sodium hydroxide, NaOH, in a coffee-cup calorimeter. The solution temperature, originally 25.0C, rises to 31.8C.
A sequence of 10 bits is transmitted over a binary symmetric channel with bit error probability Pe. Assume that bit errors occur independently. The sequence is considered to be received in error if more than two bit errors occur.
Hspice Netlist example, Often Netlist is generated by programs such as Cadence. However, on the rare occasions when one has to look at Hspice netlist
What is the difference between multiplexing and multiple access?
A machine produces photo detectors in pairs. Tests show that the first photo detector is acceptable with probability 3/5. When the first photo detector is acceptable, the second photo detector is acceptable with probability 4/5.
Calculate the amount of work done if the process is considered to be polytropic. Assume the temperature to be 273K and the value of k for the process to be 1.4. All losses are neglected.
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
A 74x163 counter is hooked up with inputs ENP, ENT, and D always HIGH, inputs A, B, and C always LOW, input LD_L = (QA.QC)', and input CLR_L = (QB.QD)'. The CLK input is hooked up to a free-running clock signal.
